Japan's parliament has passed a bill to establish a secondary capital, ending a week of intense debate. The legislation clears the way for the parliamentary session to conclude on Saturday after 158 days. The bill, which has been contentious, aims to create a backup location for government functions, though details remain vague. Lawmakers argued fiercely over the necessity and cost of the measure. Proponents say it would ensure continuity of government in case of a disaster in Tokyo, while critics question its urgency and expense. The passage marks a significant step for the ruling coalition, which pushed for the bill despite opposition. The session, one of the longest in recent years, saw numerous delays and confrontations. With the bill now law, parliament will adjourn, ending a period marked by political tension. The secondary capital plan has been debated for years, with some regions competing to host the new facilities. The government has not yet announced a location. Observers note that the bill's approval could reshape Japan's administrative structure, but implementation details are expected to be worked out in coming months. The ruling party hopes the move will boost its standing ahead of future elections.
