How to Translate a Japanese Birth Certificate for UK Visa Applications
A step-by-step guide to getting your Japanese birth certificate (戸籍謄本 Koseki Tohon) translated into English and certified for UKVI.
Do You Need to Translate Your Japanese Birth Certificate?
Applying for a UK visa with a birth certificate from Japan? You need a certified English translation that meets UK Visas and Immigration (UKVI) rules. Japan does not issue birth certificates the way most countries do. It uses a family registry system called the Koseki (戸籍). So you need to know which document to translate.
UKVI Requirement
The UK Home Office needs a certified translation with every document that is not in English or Welsh. So your Japanese birth certificate must come with certification from a qualified Japanese translator. That statement confirms the translation from Kanji, Hiragana, and Katakana into English is accurate and complete.
Understanding Japanese Birth Documents
Koseki Tohon (戸籍謄本) - Full Family Registry Extract
This is the fullest document. It shows your whole family registry: your birth details, your parents, and sometimes your siblings. Most UK visa applications ask for this one.
Koseki Shohon (戸籍抄本) - Individual Extract
A part-extract that shows only your own details from the family registry. UKVI accepts it, but it holds less than the Koseki Tohon.
Shussei Todoke Kisai Jiko Shomeisho (出生届記載事項証明書)
Certificate of Matters Stated in Notification of Birth. This one looks more like a Western birth certificate. You can use it instead of a Koseki extract.
What Makes a Japanese Birth Certificate Translation UKVI-Compliant?
A UKVI-ready translation of your Japanese birth certificate must have:
Complete Translation
Every word of the Japanese document in English. That means all Kanji characters, official seals (印), and city office stamps
Translator Certification
A signed statement that gives the translator's Japanese-English qualifications and confirms the work is accurate
Translator Details
The full name, qualifications, signature, and contact details of the Japanese translator
Date of Translation
The date the translation was finished, shown clearly
Step-by-Step: How to Get Your Japanese Birth Certificate Translated
Obtain Your Japanese Birth Certificate
Ask for your Koseki Tohon (戸籍謄本), or another birth document, from:
- The city or ward office (Shiyakusho/Kuyakusho 市役所/区役所) that holds your family register
- The Japanese Embassy or Consulate in London, if you are a Japanese citizen living abroad
- Online, through some city e-services
- Family in Japan, who can ask for it on your behalf
Upload Your Document
Send a clear scan or photo of your Japanese birth certificate to a UKVI-certified translation service. The system then:
- Spots that it is in Japanese
- Counts the pages
- Gives you an instant quote

Unique Challenges with Japanese Birth Certificates
Name Order and Romanization
Japanese names normally put the family name first, as in 田中太郎 Tanaka Taro. Your translator must romanize the name using the Hepburn or Kunrei-shiki system, so it matches your passport exactly.
Important: the English spelling must match your passport. If your passport says "Taro Tanaka," the translation should use that Western order too.
Kanji Character Translation
Japanese birth certificates use three scripts: Kanji (Chinese characters), Hiragana, and Katakana. Your translator must handle all three, including difficult characters in names and addresses.
Japanese Calendar (Reiwa/Heisei/Showa)
Japanese documents use the imperial calendar, so Reiwa 7年 means 2025. The translation must give the Western date and still note the Japanese era.
Address Format
Japanese addresses run the opposite way round to Western ones: Prefecture → City → District → Block → Building. The translation must set them out correctly in English.
Common Questions About Japanese Birth Certificate Translation
How much does it cost to translate a Japanese birth certificate?
Standard UKVI-certified translation costs £17.99 per page, delivered in 24 hours. The 8-hour rush service costs £29.99 per page. Most Koseki Tohon are 1-2 pages.
Should I translate Koseki Tohon or Koseki Shohon?
UKVI accepts either one. The Koseki Tohon (full family registry) gives more detail, so most people use it. The Koseki Shohon (individual extract) is fine as long as it shows all your birth details.
Can I translate my own Japanese birth certificate if I'm bilingual?
No. The UK Home Office will not accept a translation you did yourself, or one done by a relative. That is true even if you are fluent in both languages. You must use a professional service that provides certification to UKVI standards.
Do I need to legalize my Japanese birth certificate?
Usually not. For UK visas you do NOT normally need legalization or an apostille on a Japanese birth certificate. You DO need a certified translation that meets UKVI rules. Check the rules for your visa type.
How should Japanese dates be translated?
Your translator converts Japanese imperial dates (Reiwa, Heisei, Showa) into Western dates. For example, "令和7年1月19日" becomes "January 19, 2025", with a note saying "Reiwa 7" if that helps.
What if my name contains rare Kanji characters?
Professional Japanese translators work with rare Kanji (旧字体) and unusual characters often. They will romanize your name to match your passport, even when the characters are uncommon.
Is the translation accepted for all UK visa types?
Yes. UKVI-certified translations work for every UK visa category. That includes student visas, work visas, spouse visas, settlement, and citizenship.
How Much Does Japanese Birth Certificate Translation Cost?
Standard pricing is £17.99 per page, delivered in 24 hours. A typical 2-page Koseki Tohon costs £35.98. Japanese documents need a specialist to handle Kanji, Hiragana, and Katakana. Even so, this costs far less than the £80–£200 traditional agencies charge for the same work. Rush 8-hour delivery costs £29.99 per page. A single-page Koseki Shohon starts at £17.99.
Why UKVI Rejects Japanese Birth Certificate Translations
These mistakes get Japanese birth certificate translations rejected by the Home Office. Avoid them:
Name romanization does not match the passport
UKVI rejects a translation when the romanized name does not match the passport. Say the translation reads "Yamada Hanako" but the passport reads "Hanako Yamada" in Western order. That is a mismatch. Check your passport for the name order and spelling system before the translation is finished.
Japanese era dates not converted to Western calendar
Dates such as "令和7年" or "平成30年" must become Western dates: 2025 and 2018. If a translation leaves era dates as they are, or converts them wrongly, UKVI caseworkers treat it as incomplete.
Municipal seals and stamps omitted from translation
Koseki documents carry city seals (市区町村長之印) and office stamps that prove they are genuine. If the translation skips them, UKVI counts it as partial and rejects it. Check that your service translates every stamp and seal.
Incorrect document type submitted
Many people send a Juminhyo (resident registration) instead of a Koseki extract. A Juminhyo proves your address and household, not your birth. UKVI needs the birth details. So always use a Koseki Tohon or Koseki Shohon as your birth certificate.
The Koseki System: What UK Visa Applicants Need to Know
Japan's Family Registry System Explained
Japan's Koseki (戸籍) system is one of the oldest population registers in the world. It dates back to the 7th century. A Western birth certificate belongs to one person. A Koseki is a household register that records the civil status of a whole family. Once you know how it is built, it is easier to give UKVI the right document.
Each family has one Koseki, held at a set city office (本籍地 — honseki). A new Koseki is opened when you marry or divorce. So your birth may be recorded in your parents' Koseki rather than your own. You may need to ask for that older register.
Koseki Tohon vs Koseki Shohon: Which to Request
A Koseki Tohon (謄本) is a full copy of the family register. It lists every family member, past addresses, and all civil events. A Koseki Shohon (抄本) is an extract with only your own details. UKVI accepts either. Most people send the Tohon, because it gives caseworkers the extra context they use to check family relationships.
Requesting Koseki from Abroad
Already in the UK? You can ask the Japanese Embassy in London, or write to your registered city office in Japan. Some city offices also take requests through Japan's My Number portal. Allow 2–4 weeks. A relative in Japan can also collect it for you with a power of attorney (委任状).
Dual Nationals: Which Document to Use
Japanese-British dual nationals may hold both a Koseki and a UK birth certificate. Use the document from the country where the birth was registered. Born in Japan? Use the Koseki Tohon with a certified translation. Born in the UK? Your English birth certificate needs no translation.
Removing Personal Information (Masking)
Some people ask for a masked Koseki (一部事項証明書) to keep family details private. But UKVI wants the complete, unmasked document. If you send a masked one, your translator has to flag the gaps. UKVI may then ask for the full version.
Understanding the Koseki System: 戸籍謄本 vs 戸籍抄本
Japan's Koseki (戸籍) system works nothing like Western birth registration. Japan does not give each person their own birth certificate. Instead it keeps one household register per family, held at a single city office. That register records every civil event: births, marriages, divorces, and deaths. Before you order documents from Japan, learn the difference between the two main extracts.
What the Koseki System Records
The Koseki sits at your family's honseki (本籍地 — registered domicile). That address may not be where you live now, or where you were born. When someone marries, they usually start a new Koseki at a new address. So your birth is recorded in your parents' Koseki, not in a register of your own.
For a UK visa, you need an extract from the right Koseki: the one with your birth record on it. Do not know your parents' honseki address? Contact the city office where you think it is held, or ask the Japanese Embassy in London for help.
戸籍謄本 Koseki Tohon — Full Family Register Extract
What it contains:
- Every family member currently on the register
- Full birth details for each of them
- Every marriage, divorce, and death on this register
- Past registrations and moves between city offices
- Adoptions, legitimation events, and name changes
- The city stamp and the registrar's signature, which prove it is genuine
Best for UK visa use when:
- You are applying for a spouse or family visa, and must prove family links
- You are applying for settlement or citizenship, and need full identity evidence
- UKVI has asked you for a "full birth certificate" or "family register extract"
- You must prove your parents' names and whether they were married when you were born
Page count: usually 1–4 pages. It depends on the size and history of the family. Registers run longer where there have been several marriages or many members.
戸籍抄本 Koseki Shohon — Individual Extract
What it contains:
- Your individual birth information only
- Your parents' names and their registered details
- Your own marriages and divorces, if you have any
- A city stamp confirming this is a true extract
- Does NOT show siblings or other family members
Best for UK visa use when:
- You are applying for a work or student visa, so only your own identity matters
- You want privacy, because it leaves out other family members' details
- UKVI specifically requests an individual birth extract
- Your family register is big, so a full Tohon would run to many pages
Page count: usually 1–2 pages. It is shorter than the Tohon, so it is quicker to translate.
Important: Computerised vs Handwritten Koseki
Japan computerised the Koseki system in the 1990s and 2000s. Registers from before then may still be handwritten (手書き戸籍). Was your birth registered before computerisation? Then you may need a "historical Koseki" (改製原戸籍 — kaiseihara Koseki) from the city office that first held it. These handwritten records need a specialist translator and take longer. Tell your translation service if you think you have one.
How to Obtain Japanese Documents from the UK
Are you already in the UK and need a Koseki Tohon or Koseki Shohon for your visa? You have several options. Each one takes a different amount of time and asks for different things.
Option 1: Japanese Embassy or Consulate in the UK
Japanese nationals living in the UK can ask for Koseki extracts at the Embassy of Japan in London, or the Japanese Consulate-General in Edinburgh or Manchester. You fill in a request form and show your Japanese passport as ID. The Embassy then sends the request to your family's city office in Japan. Allow 4–8 weeks for the work and the return post.
- You need Japanese nationality, or written permission from a relative who has it
- Fee: usually a few hundred yen, paid in yen or the same value
- Documents come back by registered post to your UK address
- Embassy website: www.uk.emb-japan.go.jp
Option 2: Direct Request to the Japanese Municipality
You can write straight to the city or ward office (市役所 Shiyakusho or 区役所 Kuyakusho) that holds your family's Koseki. Most take requests from abroad by post. Send a written request in Japanese (or a bilingual form), a copy of your passport, and an International Reply Coupon (国際返信切手券) for the return postage. Allow 3–6 weeks, plus the time the post takes.
- You must know your family's exact honseki address
- Fee: usually 450–750 yen per extract, paid by international money order
- A few city offices accept English, but most want Japanese
Option 3: Japan's My Number (マイナンバー) Online Portal
People on the My Number (マイナンバー) system can order civil documents online through the government Mynaportal (マイナポータル) site. Not every city office offers this yet. It is the fastest route, sometimes only a few days. But you need a live My Number card, a card reader that works with it, and a Japanese delivery address. So it mainly helps people who arrived in the UK recently and still have a Japanese address on record.
- You need a live My Number card (マイナンバーカード) and its PIN
- It will not work once you have deregistered your Japanese address
- Documents go to a registered Japanese address or a convenience store
Option 4: Power of Attorney (委任状 — Ininjō)
Do you have family or a close friend in Japan? You can authorise them to collect the Koseki for you with a power of attorney (委任状 Ininjō). They go to the city office in person with your signed authorisation, their own ID, and your request details. This is often the quickest route, because nothing has to travel by international post. They can then scan the Koseki and email it to you for translation, and post the paper copy afterwards.
- You need someone reliable in Japan with time to visit the city office
- You must sign the power of attorney, and it is best to have it notarised
- Your representative collects the original and posts it to you
Planning Ahead: Allow Sufficient Time
Getting a Koseki from Japan by post takes 3–8 weeks, depending on the route. Then add 24 hours for the certified translation. If your visa has a firm deadline, start the Koseki request at least 2 months before you submit. Need it sooner from the UK? Call the Japanese Embassy in London first, as they may know a faster option.
