How we checked
Last checked October 20, 2026 against kawarayu.jp. Before anything appears here, a separate check fetches each source again and confirms that every date we show is in the quoted text.
Notes from the last check
The festival is verified as operating on an official annual rule (every 20 January, 5 a.m.) with the 2026 edition evidenced by a tourism-board page, but the 2027 date rests on that rule and no 2027 announcement was found.
