Ruling party officials said the secondary capital bill is unlikely to pass before the current Diet session ends on July 17 [1].

The stalemate threatens the government's legislative timeline for redistributing administrative functions, potentially delaying a significant structural shift in Japan's governance.

The bill passed the House of Representatives on July 15 [1]. However, it has not yet entered deliberations in the House of Councillors because opposition parties have not agreed to a schedule [1], [2]. The Liberal Democratic Party proposed starting the Upper House deliberations on July 16 [1].

Due to the deadlock, officials are considering extending the session by approximately one week [1]. While some reports suggest the extension could last as long as one month [2], other sources indicate a memorandum is being drafted to allow for up to two extensions [3].

Chief Cabinet Secretary Kihara said the government did not envision a Diet based on the premise of an extension and is not seeking management that assumes such a delay [1].

Despite the government's stance, other political factions are pushing for a resolution. Secretary General Nakatsukasa of the Japan Innovation Party said he requested that the bill be passed, even if it requires an extension beyond the current session [2]. The LDP and the Japan Innovation Party held meetings regarding the bill on July 15 [2].

The current impasse highlights the friction between the ruling coalition and opposition members over the speed and scope of the secondary capital designation. With the July 17 deadline approaching, the pressure to reach a compromise on the legislative calendar has intensified.

The inability to pass the secondary capital bill by the scheduled end of the session reflects a broader struggle for legislative control in the Diet. By forcing a session extension, opposition parties can either extract concessions from the ruling LDP or delay the decentralization of Tokyo's administrative power, which remains a contentious political issue.
