Really interesting comment, I know a bit about the salary-man culture with business men asleep in subways/alleys as they had dinner drinking sessions that extended past the last subway ride back to their home stations. I wonder how this practice came to be culturally? Was it something that manifested after WWII where the country felt like it needed to 'catch up' to the US and other allied countries? Or was this always a thing there? As for paper, calligraphy is a revered art form there, as well as stationary and writing letters. So being really into paper and forms does not surprise me.
