TL;DR

Japanese bank statements from MUFG, SMBC, Mizuho, and Japan Post Bank (ゆうちょ銀行) require special handling for Kanji characters, Zenkaku (full-width) numbers, and YYYY/MM/DD date formats. ClearlyLedger's Japanese-language header dictionary reads all of it directly, without you re-typing anything by hand.

Why Convert Japanese Bank Statements to Excel?

Most PDF-to-Excel converters are built and tested against Western character sets, which is exactly where they fail on Japanese statements (取引明細書). Two separate problems stack on top of each other: the text itself mixes Kanji, Hiragana, and Katakana in ways that break naive text extraction, and the numbers are often printed in Zenkaku (full-width) digits like "123" that look like numbers to a human but aren't recognized as numeric by a parser expecting standard ASCII digits. A converter that solves only one of these two problems still fails on Japanese statements.

ClearlyLedger automatically recognizes statements from major Japanese banks and handles the complexities of Japanese text processing.

Major Japanese Banks Supported (対応銀行)

Our converter handles statements from Japan's major financial institutions:

MUFG Bank (三菱UFJ銀行)

As Japan's largest bank by assets, MUFG (Mitsubishi UFJ Financial Group) statements are the format ClearlyLedger encounters most often from Japanese users. MUFG's PDFs typically run several transactions to a page with full Kanji merchant names, which need consistent character encoding to survive extraction without turning into garbled placeholder characters.

SMBC (三井住友銀行)

Sumitomo Mitsui Banking Corporation labels its transaction types directly in Japanese, 振込 for transfers and 引落 for automatic withdrawals, rather than using a generic debit/credit column. ClearlyLedger reads these labels to classify transactions instead of relying on a sign convention that SMBC's PDFs don't consistently use.

Mizuho Bank (みずほ銀行)

Mizuho statements pack in more transaction-code detail than some competitors, useful for reconciliation, but the codes are interleaved with the merchant name in the same field, so ClearlyLedger separates the two rather than treating the whole string as a single description.

Resona Bank (りそな銀行)

Resona's reference-number format is its own convention, distinct from the megabank formats above, which means a converter tuned only for MUFG, SMBC, and Mizuho will typically misparse Resona statements. ClearlyLedger treats each bank's reference format separately rather than assuming a shared standard exists.

Japan Post Bank (ゆうちょ銀行)

Japan Post Bank, still widely known by its former name Yucho, identifies accounts with a 記号・番号 (symbol and number) pair instead of the branch-and-account-number scheme the megabanks use. ClearlyLedger recognizes this identifier format rather than trying to force it into a standard branch-code field.

Japanese Format Challenges (日本語フォーマットの課題)

Japanese statements bring their own set of formatting quirks that a Western-tuned parser typically misses:

  • Kanji Characters: Proper encoding and display of Japanese text (漢字、ひらがな、カタカナ)
  • Zenkaku Numbers: Full-width numbers (123) converted to standard digits (123)
  • Date Formats: YYYY/MM/DD and Japanese era dates (令和, 平成)
  • JPY Currency: Yen symbol (¥) and comma-separated thousands
  • Transaction Types: 振込 (transfer), 引落 (withdrawal), 入金 (deposit) labels
  • Branch Codes: 3-digit branch codes (支店コード)

APPI Compliance & Privacy (個人情報保護)

Japan's Act on the Protection of Personal Information (APPI/個人情報保護法) requires careful handling of personal financial data. ClearlyLedger addresses this by:

  • The PDF is held in memory only for the run itself — nothing is written to disk once conversion completes
  • Account and 記号・番号 identifiers can be masked before you download the file
  • Statements are never retained or reused past the conversion you asked for (データ非保存)
  • Kanji and Zenkaku text run through the same conversion pipeline as any other input — there's no separate handling that would create a second place your data passes through
