Background

Why Japanese official letters are so hard

Japanese government correspondence uses formal written Japanese (書き言葉) with legal terminology, honorific language (敬語), and dense kanji compounds. Even fluent Japanese speakers find 役所の手紙 (government office letters) challenging. For expats who can barely read hiragana, these letters are completely opaque — yet they contain critical deadlines, tax obligations, and immigration requirements.

Common Letter Types

What's in your envelope?

税務署 (Zeimusho) — Tax Office

Income tax notices, withholding tax adjustments, and year-end tax settlement letters. Japan's tax year ends March 31, with filing due by March 15.

市役所/区役所 (City/Ward Office)

Resident tax (住民税), National Health Insurance (国民健康保険), pension notices, and residence registration. Multiple letters per year.

入管 (Immigration Bureau)

Visa renewal notices, status of residence changes, re-entry permits. Missing deadlines can void your visa.

年金事務所 (Pension Office)

National Pension (国民年金) enrollment and payment notices. Even short-term residents may need to enroll and can claim refunds when leaving.

You can't even read the envelope

In Germany or France, you can at least sound out the words and guess. In Japan, if you don't read kanji, the letter is a wall of symbols. You don't know if it's a tax bill, a pension notice, or a summons. Google Translate with camera mode helps with individual words but completely mangles the legal context. Meanwhile, the deadline printed in the corner is ticking.
