Is this suitable for the 650,000 yen Blue Return deduction?

Absolutely. It supports the double-entry bookkeeping (複式簿記) required for the maximum Blue Return deduction in Japan.

How does this skill handle Japanese account codes (勘定科目)?

The skill uses an internal account master to suggest codes based on transaction descriptions. For example, keywords like 'Train' or 'Taxi' trigger suggestions for Travel Expenses (旅費交通費).

Can I import data from physical paper receipts?

Yes, the skill works with OCR capabilities to read receipt images, extract the date, amount, and vendor, and then convert them into ledger entries after your confirmation.

Does it prevent duplicate entries when importing CSV files?

Yes, it includes a multi-layer check system that verifies file hashes and performs similarity checks on individual transactions to prevent double-counting.

What happens if the AI incorrectly categorizes an expense?

The skill is designed with a 'User Confirmation' step. It presents the estimated entry to you for review and allows for manual correction before anything is saved to the database.
