There was also a gashapon with some pretty cool looking OC art. It turns out it was a collaboration (though I've forgotten the name), and my friend tried to buy some of the hoodies afterwards. Unfortunately, they didn't accept foreign credit cards :frierendisappointed1:
The first floor also has a couple of arcades. This was where I saw Eiketsu Taisen for the first time, which was unlike any arcade game I've ever seen. Even as arcades died out in the rest of the world, Japan was still innovating in this space!
I also saw the three musketeers of Japanese arcade gambling: pachinko, slots and horse racing. I didn't expect the last two, tbh.
