Im in Tokyo for 10 days and was wondering if theres a place where maybe they got more soundtracks on vinyl than CDs. I know Japan is big on game OST so Im trying to see if they got any retro Vinyl on Gundam, Macross or game ones such as Snatcher etc. I saw a few at Nakano Broadway but at least to me that was obscure anime show ost so wasnt interested. In Akihabara at least the many shops I did visit, havent seen vinyl, just tons cd ost. Any advice would be appreciated.
Tbh, Akihabara is good in terms of selection, but not good in terms of price. E.g. Super Potato is good fun since it has an arcade upstairs and a wide variety of games, hardware and consoles, but it's more expensive than second-hand places. I would recommend hunting around in Book-Off stores, that's where I've seen the most OSTs for games - hope you've practiced your katakana - I only know hiragana, which left rifling through game CDs for a long time haha.
Try Recofan or Disk Union (used record store chains). They usually have a decent selection of anime stuff; game OSTs are a bit scarcer.
