Learn Japanese for Moving to Japan: First Steps & Registration

By Language Lab editorial team

Japan's city hall registration, My Number and bank setup require Japanese. The essential phrases before landing in Japan, in 2026.

What Japanese do you need when moving to Japan?

Japan requires every foreign resident to register at their local city hall (市役所, shiyakusho) within 14 days of arriving with a residence card (在留カード, zairyū kādo). This registration establishes your jūminhyō (住民票, resident registration record), which is the document you need to open a Japanese bank account, obtain a My Number (マイナンバー), enrol in the national health insurance system (国民健康保険, kokumin kenkō hoken), and complete most other administrative tasks. City hall appointments are largely conducted in Japanese — some larger ward offices in Tokyo have English-speaking staff, but this cannot be relied upon outside major urban centres. The registration vocabulary is specific: zairyū kādo, jūminhyō, hōmonsaki (address you are visiting), shakuyakunin (landlord), and honnin kakunin shorui (identity verification documents). Understanding what the officer is asking the first time saves repeat visits that can each take a full morning.

After city hall registration and My Number, the next Japanese-language priorities are opening a bank account (essential for salary receipt and bill payment) and enrolling in national health insurance. Japanese banks require your zairyū kādo, your jūminhyō, and your hanko (personal seal) or signature, and the application forms are in Japanese. Healthcare enrolment at the ward office involves a short interview in Japanese about your employment status and income level. Japanese uses three writing systems — hiragana, katakana, and kanji — which makes written comprehension a longer-term project, but spoken administrative Japanese for these specific appointments is learnable quickly through scenario practice focused on the relevant vocabulary. Language Lab's Japanese scenarios cover the city hall registration, the bank appointment, and the clinic visit, practised as voiced interactive dialogues with in-context corrections.

Key Japanese phrases for city hall registration and first appointments

Why Learning Japanese Before You Move to Japan Changes Everything

Moving to Japan without any knowledge of Japanese means arriving without the tools for your most important first-month tasks. Administrative processes — registering your address, opening a bank account, completing jūsho todoke (address notification), registering with a doctor — happen primarily in Japanese. Officials rarely speak English well enough to guide you through paperwork, and the questions they ask are not always the ones you prepared for. Expats who arrive with even basic Japanese — enough to follow the structure of an official conversation and ask for repetition — report dramatically smoother first months than those relying entirely on translation apps.

Language also shapes your wellbeing in Japan. Research on expat adjustment consistently shows that the ability to hold a simple conversation in the local language, even imperfectly, reduces isolation and accelerates the shift from tourist to resident. When you can greet your neighbour in Japanese, ask a shopkeeper a question, or follow what is being said at a community meeting, you feel present in Japan rather than passing through it. That sense of belonging is the most underrated benefit of language investment and the one that expats who skip language learning most often regret.

What Level of Japanese Do You Actually Need?

For day-to-day life in Japan, A2–B1 is the practical target. At A2, you can handle basic transactions, ask for directions, follow simple written forms and signs, and navigate most structured interactions (like a registration appointment) if you have prepared the vocabulary in advance. At B1, you can hold a basic conversation on familiar topics, understand the gist of official correspondence, and handle unexpected questions in bureaucratic contexts. Full fluency is not the initial goal — functional, purposeful language use in the situations you actually face is.

For professional integration in Japan, B2 is generally the minimum if your role involves any client or colleague communication in Japanese. Japan workplaces vary enormously: international companies in Tokyo often operate partly in English, while smaller or regional businesses work exclusively in Japanese. Career growth within Japan — beyond the initial international-hire phase — almost always requires B2 or above. Many expat communities in Japan plateau at B1 because English is available as a fallback; pushing past B1 requires deliberate commitment to using Japanese even when defaulting to English is easier.

Understanding Japanese: Difficulty and Structure

The Foreign Service Institute classifies Japanese as a Category IV language for English speakers, requiring approximately 2200 hours of structured study to reach professional working proficiency (roughly C1). Japanese requires three writing systems: hiragana (learned in 1–2 weeks), katakana (another 1–2 weeks), and kanji (2136 standard characters — a multi-year project). Daily literacy requires approximately 1000–1500 kanji. This means Japanese is one of the most demanding languages for English speakers due to its script, tonal system, or deeply different structure. FSI estimates are based on intensive classroom instruction; self-study with good tools combined with immersion in Japan can achieve similar or better results at a slower calendar pace.

Japanese verb-final structure, topic-marking particles, and keigo (honorific speech levels) create a communication system that differs fundamentally from English. The absence of plural markers and grammatical gender simplifies some aspects. Understanding this upfront means you approach Japanese with the right strategy: not trying to learn everything at once, but building the vocabulary and patterns for the specific situations you will actually encounter in your first months in Japan. The language of the registration office, the bank, the landlord, and the doctor — this targeted set is learnable far faster than general fluency, and it gives you functional capability exactly where you need it first.

jūsho todoke (address notification): What Japanese You Need

One of your first tasks in Japan will be completing jūsho todoke (address notification). This is notifying your address at the local shiyakusho within 14 days. The process involves presenting documents, answering official questions, and understanding written notices — all primarily in Japanese. Preparation is key: knowing the vocabulary for document types, understanding what the official is asking, being able to confirm your details and ask for clarification — these specific language skills determine whether the appointment takes 15 minutes or becomes a confusing hour-long ordeal requiring you to return with a translator.

The vocabulary for jūsho todoke (address notification) is highly domain-specific. Many learners who know general Japanese for daily conversation have large gaps in administrative vocabulary — words for residency status, identification types, registration categories, and government terminology appear in textbooks rarely but in the shiyakusho (city hall) constantly. Building this administrative vocabulary deliberately, through scenario practice rather than abstract drills, means you walk into the shiyakusho (city hall) appointment already familiar with the terms you will hear.

• "Ginkou kooza wo hirakitai desu" — for opening your first bank account in Japan
• "Kokumin kenko hoken ni touroku shitai desu" — for registering with a local doctor or health provider
• "Chintai keiyaku ni tsuite shitsumon ga arimasu" — key phrase for landlord communication
• Document vocabulary: residence permit, proof of address, identification number, registration certificate
• Clarification phrases: "Could you repeat that more slowly?" / "What does this form require?"
• Confirmation phrases: "So I need to bring..." / "The appointment is at..." / "Is this correct?"

Banking in Japan: The Japanese You Need

Opening a bank account in Japan is one of the first practical necessities after arrival, and it requires navigating financial terminology in Japanese. Even banks with English websites often conduct in-branch appointments in Japanese. You will need to understand account types, monthly fee structures, direct debit mandates, card terms, and the conditions of any credit facilities. Understanding — or at minimum recognising — these terms means you are not signing agreements you do not understand and not missing deadlines buried in Japanese correspondence.

Once your account is open, financial correspondence from Japan authorities (tax office, social insurance, employer payroll systems) arrives in Japanese. Learning to identify which letters require urgent action — and what that action is — protects you from missing deadlines or defaulting on obligations through language misunderstanding. Building financial and administrative vocabulary in Japanese early is one of the highest-return language investments for newcomers to Japan.

Healthcare in Japan: Medical Japanese That Matters

Registering with a doctor or health insurer in Japan is an early priority, and it happens in Japanese. Describing symptoms, understanding a diagnosis, following medication instructions, knowing your healthcare entitlements — all of these are language-dependent. In any medical situation, the ability to communicate accurately in Japanese directly affects the quality of care you receive. Most expats who have experienced a health problem in Japan without adequate Japanese describe it as among the most stressful situations of their relocation.

Healthcare Japanese is more learnable than it seems. The most important phrases fall into predictable patterns: describing where it hurts and since when, asking for an interpreter if needed, understanding when to return and what medication to take. Practicing these scenarios before you need them — through Language Lab's medical scenario practice or other tools — means you have already run through the conversation before the stakes are real.

Working in Japan: Professional Japanese

If you are moving to Japan for work, your Japanese needs extend into professional contexts. Workplace Japanese has its own register — more formal than daily conversation, with specific vocabulary for meetings, emails, performance reviews, and HR processes. Many expats find that spoken Japanese improves quickly through daily life, but written professional Japanese — particularly email formality and document tone — requires more deliberate attention. Making the effort to write professional emails in Japanese, even initially with help, signals commitment and is noticed by colleagues.

Colleagues in Japan are generally patient with foreign speakers of Japanese, especially those who are visibly trying. The turning point for many professional expats comes when they stop defaulting to English in every meeting and start attempting Japanese — imperfectly but genuinely. The awkward months of public mistakes are the price of the confidence and connection that come after. Language Lab's professional scenario practice helps prepare you for these moments before they are real.

Cultural Integration Through Japanese

Language is the primary vehicle for cultural integration in Japan. Understanding local humour, following news and conversations about current events, participating in casual social exchanges — these are the interactions that move you from "foreigner" to "resident" in the eyes of your community. Expats who invest in Japanese beyond transactional minimum consistently report higher long-term happiness and deeper social networks in Japan than those who remain in English-language expat bubbles.

The organic Japanese of daily life in Japan — idioms, slang, cultural references, conversational rhythms — cannot be fully learned from structured courses. Immersion completes what formal study starts: watching local TV, listening to local radio, reading local news in Japanese, joining local groups where English is not the default. Each of these exposes you to language that textbooks do not capture, and each accelerates your sense of belonging in your new home.

Practical Study Timeline for Japanese Before Your Move

Common Mistakes Expats Make Learning Japanese

The most common mistake is focusing on tourist vocabulary rather than relocation vocabulary. Standard beginner courses teach you to order food and ask for directions — useful, but not what you need when a shiyakusho (city hall) official asks why your registration document shows a different address from your rental contract. Targeting the language of the situations you will actually face, not the situations language textbooks assume you will face, is the most efficient preparation for a move to Japan.

The second most common mistake is delaying. Many people plan to start learning Japanese after arriving in Japan, assuming they will pick it up through immersion. Immersion accelerates language learning, but only if you already have a foundation. Arriving with zero Japanese and hoping to absorb it passively means weeks of confusion and reliance on English-speaking intermediaries for every administrative task. Even three months of basic preparation before your move changes the experience fundamentally.

The AI Advantage: Practicing Japanese for Japan Before You Arrive

AI language tools have changed what is possible for self-directed learners preparing for a specific move. Unlike apps that drill vocabulary in abstract contexts, conversational AI lets you practice the exact scenarios you will face in Japan: the shiyakusho (city hall) appointment, the bank visit, the landlord phone call, the doctor's reception. You can make mistakes without embarrassment, ask for explanations in English, and repeat the same scenario until it feels natural. The feedback is immediate and the practice is available at any time.

Language Lab is built specifically for this use case — the Japanese of life in Japan, not the Japanese of a holiday. The Street Smart scenario library puts you in realistic relocation situations: the shiyakusho (city hall) counter, the first conversation with your landlord, the GP receptionist. You practice these moments before they are real. Sonia, the AI tutor, provides feedback and corrections in the style of a knowledgeable friend, adapting to your level and noting the specific mistakes you repeat most.

The Science of Remembering Japanese: How to Make Learning Stick

One of the most persistent frustrations in language learning is the experience of learning a word or phrase, feeling confident about it, and then completely blanking when you try to use it a week later. This is not a failure of ability — it is how memory works. New information moves from short-term to long-term memory through repetition spaced over time, not through a single encounter. The spacing effect, documented in memory research since the 1880s, shows that studying material at increasing intervals (today, then in three days, then in a week, then in a month) produces dramatically better retention than repeating it multiple times in a single session.

Language Lab's platform is built on spaced repetition principles. The AI tracks when you first encountered each vocabulary item, how well you produced it under testing conditions, and when it is scheduled to reappear for optimal retention. Items you found difficult reappear more frequently; items you consistently recall correctly reappear at longer intervals. This is not a premium feature — it is the fundamental design of how the platform schedules your study content. The practical result is that less time is wasted reviewing things you already know well, and more time goes to reinforcing the items most likely to disappear from memory before you need them.

The implication for your study habits is concrete: short daily sessions beat long weekly cramming sessions for language retention. Thirty minutes every day for seven days produces more lasting vocabulary acquisition than three and a half hours in a single sitting. Language Lab's daily study design is built around this principle — the daily streak is not a gamification gimmick but an approximation of the optimal spacing interval for language retention at early-to-mid levels.

Input vs Output: Why You Need Both to Progress

The history of language teaching methodology has been a long debate about the relative importance of input (reading and listening) and output (speaking and writing). Current research consensus is that both are necessary and that they contribute differently to language development. Input builds the mental model of how the language works — the patterns, the vocabulary frequencies, the collocations that make speech sound natural. Output drives conscious attention to gaps in your knowledge — when you try to say something and realise you do not have the word, you notice that gap in a way that passive exposure does not create.

For most adult learners, the input-output balance tilts too heavily toward input. Reading, listening, and vocabulary review feel productive because they are comparatively comfortable. Speaking is uncomfortable because you can be wrong in real time, and writing is uncomfortable because errors are visible. But comfortable study is not the same as effective study. The discomfort of output — of trying to produce language you are not fully confident in — is precisely the mechanism that drives language development. Language Lab's Bestie Mode is designed to make that discomfort manageable: speaking to an AI that responds helpfully and corrects kindly reduces the social anxiety of speaking, without eliminating the productive cognitive challenge.

A practical balance for most learners: 60% input (structured lessons, reading, listening to podcasts or shows), 40% output (Bestie Mode conversations, writing practice, journal entries in Japanese). Adjust toward more output as your level increases — advanced learners benefit more from output practice than additional input because their comprehension is already strong.

The Role of Immersion Alongside Structured Study

Structured study gives you a framework — grammar rules, vocabulary organised by topic, pronunciation guides. But structure alone rarely produces the intuitive fluency that lets you respond spontaneously in Japanese without consciously translating. Intuitive fluency develops through high-volume exposure to the language in natural contexts: hearing how words are actually combined, picking up the rhythm and stress patterns of real speech, and absorbing the collocations that make native speakers sound native.

The good news is that you do not need to move to the country to achieve meaningful immersion. Changing your phone language to Japanese, following Japanese-language social media accounts on topics you care about, watching Japanese-language shows with Japanese subtitles, and listening to Japanese-language podcasts during your commute all contribute to the kind of high-volume exposure that builds intuitive fluency. These activities work alongside structured study rather than replacing it: the structure gives you the framework to make sense of the input, and the immersive input reinforces and expands what the structure taught you.

Community Learning: Why Social Accountability Accelerates Progress

Solo language learning has one significant weakness: no social accountability. When you skip a session, nothing happens except that you fall slightly behind schedule — a consequence that is easy to postpone indefinitely. Human social accountability — knowing that another person is aware of and invested in your progress — is one of the most reliable motivational forces in behaviour change. Language learning communities leverage this force while also providing something apps cannot: the experience of being understood in Japanese by another person.

Language exchange communities — both online (Tandem, HelloTalk, language learning subreddits, Discord servers for specific languages) and in-person (language cafe events, expatriate meetup groups, cultural institutions) — provide speaking partners who are genuinely motivated to help you because they are learning your language in return. The reciprocity of the exchange creates accountability in both directions. Language Lab's social features connect learners who are studying the same language at similar levels, creating an additional layer of community without requiring you to find a partner independently.

Expat Facebook groups and WhatsApp communities for your target country are also valuable — not just for the language practice opportunity but for the practical knowledge sharing that helps language study connect to real life. When someone in a Germany expat group explains exactly what German they used to navigate a difficult Anmeldung scenario, that vocabulary gains immediate relevance that textbook examples lack.

Long-Term Language Maintenance: Keeping What You Learned

Language skills decay without use — a fact that discourages some learners but should actually be reassuring. Decay is much faster for recently learned material than for deeply embedded patterns, and it is reversible. Research on language reactivation shows that returning to a language after a gap of months or even years reactivates competence much faster than the original learning required. The mental pathways are still there; they just need stimulation to reactivate.

For languages you are actively using in your new country, maintenance is automatic — immersion is itself maintenance. For languages you are preparing to use (studying before a move, before a language test, or before a job opportunity), design a maintenance strategy before you reach your goal. Define the minimum effective dose of study that prevents significant decay: for most people at B1 and above, thirty to forty-five minutes of active exposure two to three times per week prevents measurable backsliding. Dropping below this threshold for more than six to eight weeks typically produces noticeable regression.

Language Lab's design supports long-term maintenance with its spaced repetition system, which automatically resurfaces vocabulary at the intervals needed to prevent decay. Users who complete their initial goal (a move, an exam) often continue with reduced frequency sessions precisely because the platform makes it easy to maintain progress without restarting from scratch.
