Summary
The retirement of Toshihiro Nikai, a pivotal figure in Japan’s Land Resilience Plan, has left the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and the construction industry grappling with leadership challenges. Nikai’s efforts, initiated after the 2011 Great East Japan Earthquake, led to the establishment of a ¥15 trillion five-year plan (2021–2025) to bolster disaster prevention and infrastructure. However, with the plan’s conclusion approaching, the absence of a successor jeopardizes the continuation of these initiatives. The dissolution of Nikai’s faction, Shisuikai, and the failure of his son Nobuyasu to secure a political seat further complicate matters. The LDP aims to finalize a new five-year plan (2026–2030) focusing on aging infrastructure, but concerns over leadership persist. The upcoming House of Councillors election intensifies the urgency to address this void.
