High tech toilets are very common in Japan. Almost all new houses and shopping departments seem to have them. Some of the high tech toilet features include seat heating, anus/bidet washing, self flushing, and deodorizing. You might not need the features but it won't hurt to have them, right? But my sister didn't think so. She turned off the self-flushing function because there was a couple of times that she couldn't remember if she flushed the toilet or not after using restroom outside the house. That made her wonder if her kids were forgetting to flush the toilet at school or in their friend's house as well. I guess some convenient functions can be a problem when it comes to habits and manners.
