ETC statement retention periods — independent reference
For ETC Corporate Cards, the ETC Usage Inquiry Service does not issue an invoice-compliant usage certificate. Refer to the applicable monthly invoice issued under the NEXCO or card arrangement.
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.

E-Storage Act search requirements
Electronic-transaction records must generally be retrievable by transaction date, counterparty, and amount. Simply dropping PDFs or CSVs into a folder may not meet the searchability requirement.
- Include date, counterparty, and amount in the filename (e.g., 2026-04-15_NEXCO_East_1240.pdf)
- Maintain an index file (CSV or accounting-system list) searchable by date, counterparty, and amount
- Confirm that your storage system provides compliant search functionality
