Art museum a little off the beaten track but worth a visit particularly if you have a Leeloo Dallas monkey pass (sorry but that's how it was in my head every time I flashed it at a train official or bus driver!) and are looking for something to do on the way back to Nagano. 10 minute walk through friendly Obuse from the train station, with several good souvenir shops around it. The museum itself has a short video explaining Hokusai's life with English subtitles, and then 3 main sections. The first is a display of illustrated "books for reading" which are basically early manga (stories seem to revolve around monks getting drunk and deciding who is the fightiest). Second is a collection of art works by Hokusai and third is the festival floats featuring waves, a dragon and a phoenix. Be warned, "the wave" picture (i.e. The great wave of kanagawa) is not here itself, though there is a short section on its composition. At only 1000 yen for entrance it's well worth a quick stop!
