Here are some screen shots from a segment broadcast on NHK’s morning news show on July 13th. The segment says that “extremely hot days” (moshobi) are defined as days where the high is 35C (95F) or higher and that “tropical nights” (nettaiya) are nights where the temperature does not go below 25C (77F). I thought these national figures were interesting because they indicate that, when it comes to “extremely hot days,” Kumamoto is ranked 4th in the country after Kyoto, Kofu, and Gifu. (Kumamoto averages 17.7 such days each year.) Predictably, Okinawa has the most “tropical nights” but I was surprised to learn that “extremely hot days” are actually quite rare in Okinawa – just slightly more common than in Sapporo.
