MIC published final Ministerial Ordinance No. 111 and Notification No. 346 after consultation. The measures amend the terminal-equipment rules for certain dedicated-line and self-telecommunications equipment using Internet Protocol and connected to digital data-transmission facilities.

They address software-update functionality and conditions for measures relating to the security interface identified in the terminal-equipment rules. The final documents were published on September 24, 2026 and are scheduled to apply from April 1, 2027.

Impact

Impact assessment: High. Key reasons: The final instruments establish a defined 2027 compliance date and can change security, software-update and certification evidence for affected IP terminal equipment.

Who is affected?

Manufacturers and importers of IP terminal equipment, Japanese approval holders, certification bodies, test laboratories, firmware and cybersecurity teams, telecom operators and product-compliance managers.

Conclusion:

Identify in-scope terminal categories, perform a clause-level review of Order No. 111 and Notification No. 346, update software-update and interface-security evidence, and align certification plans before April 1, 2027.
