100% iron or steel in Japan

Other countries often use plastic or copper. For example in USA and Europe. Why? Do Japanese fear copper toxicity?

Content about Johkasou, any good?

I have moved the text block below from wastewater treatment. Should it be added to this article? I think some of this content is already in there and perhaps with better sources:

In Japan, since 1950s, an advanced domestic wastewater treatment system (tank) called Johkasou was developed. The system treats wastewater as clean as 20 ppm as Biological Oxygen Demand (BOD). Japan operated for 11 million Japanese people in less populated areas around Japan, as a technique which is cost‐effective and able to be installed in a short time. This system effluents properly disinfected water and protects water environment and ensure rural water resources. This system includes some technologies such as biological contactor ditch process, trickling filter process, anaerobic filter‐contact aeration process, Biofilm filtration tank, and Moving bed biofilm tank. In order to treat Johkasou, it is requires periodic maintenance of biofilm and removal of sludge. Maintenance must be performed by certified technicians or engineers.^[1] EMsmile (talk) 04:22, 26 March 2021 (UTC)[reply]

History

[1] and [2] have a lot of details that can fill in the pre-industrial history of this topic. Apparently there was a lot going on, and the history of Sewerage should be expanded to make it less Eurocentric. -- Beland (talk) 05:55, 18 December 2023 (UTC)[reply]
