1. Overview

　To prevent interference with radio communication systems or malfunctions in electrical and electronic equipment, the International Special Committee on Radio Interference (CISPR) has established tolerances and measurement methods for various types of radio disturbances, known as CISPR standards. Among the CISPR standards, CISPR 11 (Tolerances and Measurement Methods for Disturbances Emitted from Industrial, Scientific, and Medical Equipment) and CISPR 16 (Technical Requirements for Measurement Methods for Radio Frequency Disturbances and Immunity) were partially revised. In response, the Information and Communications Council deliberated on these revisions and submitted a partial report on December 8, 2025.

　In light of this situation, it is necessary to harmonize the tolerances and measurement methods for high-frequency equipment, excluding communication equipment, with those in international standards. As part of this effort, the MIC prepared the Draft Ministerial Ordinance and solicited opinions.

2. Report from the Radio Regulatory Council

　Based on the results of the opinion solicitation, the MIC consulted the Radio Regulatory Council regarding matters under the Radio Act (Act No. 131 of 1950) set forth in the Draft Ministerial Ordinance. Today, we have received a report stating that these matters are appropriate.
