Nice one. A lot of different sites and platforms struggle with Japanese characters. I discovered ages ago that
all Amazon listing URLs work best if you chop out everything except the ASIN after "dp/", like so:
https://www.amazon.co.jp/dp/B01LD4QFUU. Of course it doesn't allow for affiliate info, but often still comes in handy, like now! By the way, the Japanese label translates for me as "Junes Planning", whether going from the native or English spelling.
By a
very strange coincidence, Flicker Alley have just (as of Tuesday 18 Sept) released this film on BD - no warning whatsoever! I'll get hold of a copy and post specs unless DVDBeaver or one of you guys beats me to it.
