1. Overview

　In Japan, tire pressure monitoring systems (TPMS ) and remote keyless entry (RKE ) were introduced in 2007 as radio stations (specified low-power radio stations) that use the 315 MHz band, which does not require a license. Internationally, the 433 MHz band is widely used for TPMS and RKE systems, making it a global standard frequency for both.
　We should align with international frequency coordination and respond to domestic requests for new frequencies. The MIC consulted the Information and Communications Council, chaired by ENDO Nobuhiro, Special Advisor to NEC Corporation, regarding technical requirements for 433 MHz band tire pressure monitoring systems and remote keyless entries. After discussions, we received a partial report from the Council on the matter in November 2024.
　In response, we decided to proceed with necessary institutionalization to introduce these systems. Therefore, we solicited opinions on the draft ministerial ordinance to partially amend the Regulations for Enforcement of the Radio Act and other related rules. The opinion solicitation period ran from Saturday, November 16, 2024, to Monday, December 16, 2024.

Today, we received a report indicating that amending the Act in accordance with the content of the drafts is appropriate.
