At the current exchange rate, 35000 yen would be about £215 or so. The Japanese have long payed a premium for media content; DVD episodes of popular anime used to be 2 episodes per disc (as opposed to the more general Western norm of at least four episodes) and before that it may have been 1 - 2 episodes per videotape!  (those who used to order Anime Projects releases of "Bubblegum Crisis" from the mysterious neverland of Bangor may well sympathize!). I once actually saw in Akihabara somewhere selling Western anime releases, presumably on the basis of their greater "value"!You can usually find lower prices second-hand, which is a big market; Japanese second-hand goods tend to have been exceptionally well looked after and the premium on living space means theres an incentive to clear out older items regularly. Big chains that virtually specialise in this include "Mandarake" and - a favourite among visitors - "Book Off!" . Laserdisc was much more popular in Japan than elsewhere up to the advent of DVD, and right up to a couple of years ago (and probably still), you could still find gorgeous second-hand Laserdisc anime box sets for sale in Akihabara. This always tends to get a bit of a laugh, though I've heard it explained thats its due to the fact that certain English words are more well known than others. Book Off! has a sister chain specialising in used electronics - Hard Off!
