I'm going to be setting up my photo studio later this year, and that will involve also having a small darkroom. I'm having trouble finding any information regarding proper disposal of used photography chemicals in Japan, I assume because I'm searching for it with the wrong terms in Japanese. Different places handle it in different ways, ranging from everything down the drain being OK to everything having to be picked up for recycling to somewhere in between. If anyone has experience with this or can help me with the right Japanese words to Google, I would sincerely appreciate it. I'm living in Urawa, Saitama and will need to dispose of developer and fixer for black and white film only. No color chemicals, which tend to be nastier and harder to dispose of properly.
