ETC statement retention periods — independent reference
An independent neutral reference covering retention windows on the ETC Usage Inquiry Service, ETC Corporate Cards, and Japan's Electronic Books Preservation Act.
Short answer
The ETC Usage Inquiry Service typically retains ~15 months of statements + PDF certificates. ETC Corporate Cards typically retain ~62 days. Under Japan's Electronic Books Preservation Act, electronic-transaction records are generally required to be kept for 7 years (10 in some loss-carryover cases). You must save what you need separately. JTR organises a MEISAI-registered account's records into daily PDF + CSV + email delivery to support that retention.

※ Specific periods, requirements, and exceptions follow the National Tax Agency and each official service. This is a 2026-05 general independent reference.
e-Storage Act search requirements
Electronic-transaction records must generally be retrievable by transaction date, counterparty, and amount. Simply dropping PDFs / CSVs into a folder may not meet the search-ability requirement.
- Include date / counterparty / amount in the filename (e.g. 2026-04-15_NEXCO_East_1240.pdf)
- Maintain an index file (CSV or accounting system) searchable by these 3 fields
- Confirm your storage system provides compliant search
