I went to this building last month to take pictures ( but I do with everything in Japan. Even the 1000th torii gate). Japanese people only started to stop after I did. Japanese people don’t care about this. That’s why it’s decaying. This is equally true of other things about Japan which westerners are obsessed with. Pretty much all the stuff on Atlas Obscura. Like the Namba Shrine in Osaka, one of the more edgy tourist spots, but the majority of Osakan natives I asked did not know it existed.
You know what actually gets Japanese people wide eyed with excitement when a non-Japanese asks about it? The Shinsengumi.
Meanwhile, what’s permeating across Japan are restaurants offering ingredients and a bbq pit for DIY American style BBQ , as well as camping/glamping equipment as a “lifestyle”, setting up tents for a picnic park.
Edit: The trigger word about the article to me is “beloved”. To whom? Clearly it resonates with the HackerNews and tech crowd who romanticize that Japan/Tokyo is some futuristic cyberpunk fantasy. It’s really not. To the Japanese, this was an edgy building during experimental times in the 70s, but now it’s a liability. It just doesn’t make sense for Ginza anymore. If the concern is lost of neighborhood identity, the concern would be in the redevelopment of a bohemian neighborhood like Shimokitazawa. Otherwise, it’s like a Japanese article saying how beautiful and beloved the New York subway train graffiti of the 80s was and we shouldn’t clean it up.
