Hi daria! About 2 years ago, I stumbled upon this tweet of yours:
"A few months or so ago there was an article about an upcoming photo book of japanese houses/apartments from the late 80s/early 90s and I can't find the article or book at all. Anyone know what I'm talking about?"
Someone answered your tweet with a link to the book. Unfortunately I lost my bookmark and now the answer to your tweet is now deleted. May there be any chance you still have the book or remember its title? I just randomly remembered it and now I can't stop thinking about it. Thank you!
Yup! The book is called ROADSIDE LIBRARY vol.004：TOKYO STYLE, by photographer Kyoichi Tsuzuki. It's still available in PDF for 2,000 yen over here:
Well worth the purchase imo, even if you can't read japanese like me.
