❓ What is changing?
The Act Partially Amending the Act on Revitalization and Rehabilitation of Local Public Transportation was promulgated on June 10, 2026 and takes effect on October 16, 2026. On September 18, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) announced that four sets of rules and guidance are being put in place for the law to function: (1) the Enforcement Regulation of the Act on Revitalization and Rehabilitation of Local Public Transportation, (2) the Basic Policy on promoting revitalization and rehabilitation of local public transportation, (3) the Enforcement Regulation of the Road Transportation Act, and (4) a Guideline for promoting the use of mobility data. Items (1) to (3) were promulgated on September 18 and take effect on October 16, the same day as the law itself. Item (4) was published on September 18. The background is closing "transport gaps" (kotsu kuhaku) — areas left without adequate transport service. MLIT states that by making full use of local transport resources and promoting joint operation and collaboration among operators, it aims to realize sustainable local public transportation. Because the text of a law alone cannot move day-to-day practice, the detailed procedures, the national policy direction, the rules governing buses and taxis under the Road Transportation Act, and the data-use guidance are all being aligned at the same time. Details are published in the attached documents.
