Help finding X360 shmups I'm Tokyo

[Jotamide]

Hey all, so I'm currently visiting Tokyo and wanted to grab Bullet Soul Infinite Burst, Shikigami No Shiro III, and maybe Instant Brain (for Dodonpachi) but I wasn't able to find anything. I went to Sofmap, Trader, and Super Potato in Akiba and the Book Off in Shibuya with no luck. Spotting the X360 sections in all stores was really easy (due to the almost nonexistent Microsoft sections) but in all of them there were close to no shmups. Can anyone please point me to places where I might be able to find stock of these games? It won't be the end of the world if I can't buy them, but it would be so cool to grab at least Bullet Soul. Any help would be appreciated.

Check the Mandarake shops in Akiba and Nakano, and any large Book Off (there's a big one in Akiba).

Any book off store is also worth a look for price comparisons..

My honest advice, don’t bother looking, just order them online. If you want to spend your vacation time on videogames, then go to some arcades.

My go to place for shooters was always Messe Sanoh in Akiba but it's been a few years since I've been there.

Order online. I saw none of those games during a month in tokyo during this summer.
