This short film is just what the other reviewers have said: gorgeous, touching, memorable, all in too few minutes. I don't speak or read Japanese, so sometimes I had to guess about what was happening -- didn't matter. Still amazing. The museum is very strict in allowing each guest to see the film only once, so pay attention when you get the chance! Just adding to note that we saw the film on 19 September 2015 -- it's back and (if it's practical for you) worth a trip to Mitaka! But get your tickets in advance, as noted elsewhere. The sound track is available in the Museum store -- I'm listening as a write the review. Piano and strings with a bit of synthesizer, all lovely even if not by Mr. Hisaishi.
