Ps My toilet is JIS approved. CSA is for hipster toilet ******s. JIS is for people who actually use toilets for what they were made for first and foremost.Too many guys in the US (especially) are going around thinking they are the ****, wearing CSA t shirts and whatever else. I figure the Japanese have been using toilets for longer, and in weirder positions, so they should know a thing or two by now......just my 2 cents.
