This article provides a comprehensive guide on using toilets in Japan. It explains that travelers should not throw toilet paper in the toilet as most Japanese toilets are designed only for solid waste and flushing used tissue can cause plumbing problems. The proper way to dispose of used tissue is by placing it into a trash bin located near the toilet bowl, and there may be subtle differences between public and private restrooms. Additionally, other cultural practices such as removing shoes before entering certain restrooms and avoiding talking loudly while inside should also be kept in mind when visiting or living in Japan.
