Japanese DVD
There is a Japanese DVD available (http://www.cdjapan.co.jp/detailview.html?KEY=KKDS-215). Here are its specs:
DVD-9 (movie: 7.16 GB), NTSC, Region 2
Runtime: 118 min 48 sec (118 min 31 sec without the end table by the Japanese distributor)
Audio: English Dolby Digital 2.0
Subtitles: Japanese (removable: both, while viewing or by going to the main menu)
Aspect ratio: 1.66:1, anamorphic (pillar boxed on a 16:9 TV, letterboxed on a 4:3 TV)
Extras: Theatrical trailer (runtime: 2 min 38 sec, audio: English, no subtitles); scene selection; booklet (in Japanese)
Note: Movie starts immediately upon inserting the DVD in the player, with the Japanese subtitles on by default.
Bottom line: The DVD is a bit pricey (as most Japanese DVDs are), but when it comes to film alone (i.e. not the extras) all I was looking for for a long time.
