And indeed, Classic Components has completely disappeared from earth
Their (translated) website is a bit vague on whether it closed or not, and I missed the post of Damien above, which could have saved me the walk.
From the front of their webpage:
閉店のお知らせ!
平素より弊店を御利用賜り厚く御礼申し上げます。
さて、この度令和6年11月20日(水)をもちまして
弊店日10月31日(木)に変更になりました。
閉店することになりましたのでお知らせいたします。
お客様には大変ご迷惑をおかけし、申し訳けございません
これまで弊店をご愛顧いただき、誠にありがとうございました。
Which translates to:
Notice of Store Closure!

I think that's pretty clear?

It's too bad, they had some good stuff and I bought a bunch of tubes and databooks from them.
It's sad I'll never get to browse through racks of tubes while the old shopkeeper noisily burps and farts with alarming frequency in the corner.
