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 multi-language header support processes these formats through its secure conversion service.

Why Convert Japanese Bank Statements to Excel?

Japanese businesses, accountants, and expatriates frequently need to convert bank statement PDFs (取引明細書) to Excel for tax filings with the National Tax Agency (国税庁), business accounting, or financial analysis. Japanese bank statements present unique challenges due to character encodings and date formats.

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, MUFG (Mitsubishi UFJ Financial Group) statements are commonly processed. Our converter handles MUFG's detailed transaction listings with proper Kanji character encoding.

SMBC (三井住友銀行)

Sumitomo Mitsui Banking Corporation statements feature comprehensive transaction histories. ClearlyLedger accurately parses SMBC's format including振込 (transfers) and引落 (withdrawals) labels.

Mizuho Bank (みずほ銀行)

Mizuho statements include detailed merchant information and transaction codes. Our tool captures all fields while maintaining data accuracy across Japanese text.

Resona Bank (りそな銀行)

Resona Bank statements feature unique reference formats. ClearlyLedger maps these to clean Excel columns for easy analysis.

Japan Post Bank (Yucho) statements are widely used across Japan. Our converter handles Yucho's specific format including 記号・番号 (symbol and number) account identifiers.

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

Converting Japanese bank statements involves handling several region-specific formats:

  • 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:

  • Secure conversion with source PDFs deleted after processing
  • Optional PII masking for account numbers and personal details
  • No data retention or storage of your bank statements (データ非保存)
  • Full transparency in data processing methods
