Why don't mention the name? it's free marketing, you dumb business owner.
Our mangaka omitted the names of at least a few establishments mentioned in the series - they are not big places and they don’t want to deal with resulting sudden spike in business if it’s such an easy giveaway, which will ruin the entire point of showing you a place to reset. Japan is legendary when it came to FOMO related crowds. When the Japanese actor from the solitary gourmet TV series very recently did a Netflix show with a Korean actor and revisited a few spots, a certain upscale cake shop in a remote part of Kamakura got mobbed with foreign tourists to the point where the owner had to apologize for not having enough cakes around to serve their (usually super-boughie, Daikanyama dwelling) customers and tying up the local roads with extra traffic trying to get into their parking lot…
Of course, obscuring it just a little bit did help deter the low-hanging fruit looky-Lous, but the clues are out there and it’s not that hard to find. It’s not that they mind the extra business, it’s that a sudden burst of business due to a direct manga mention don’t tend to stick around for long, especially for those relatively remote places - enough for people to complain and the owner to have to deal with the crowds, but not enough to change the needle much long term.
Update: they
closed down that location in late 2024/early 2025 and moved up the mountains. I guess between Chapter 127’s Japanese release in December 2023 and last year, they probably didn’t gain that much more business and had to move to a cheaper area. Their new area seem to have more steady business from the locals, and to them it’s almost like semi-retirement anyways.
There’s a
art studio/full sit-down place next to their old location - that one is probably just as much of a reset spot and will probably be better for the crowds.
