RAW JAPAN Take
Hot springs × anime? That combo is unbeatable.
Characters in post-bath yukata already feel divine—but add in original merch based on brand-new art? Yeah, that’s bliss.
And the fact that there’s online ordering after the event? Considerate and dangerous for our wallets.
Personally, I’ll be soaking in the spa until I pull my fave can badge—gotta be ready for that post-bath trading sesh.
