Japanese people use a variety of toilet paper options including standard white toilet paper, moist toilet wipes, and bidets/washlets. Hygiene and cleanliness are important cultural values in Japan, which is why many people prefer bidets or washlets over traditional toilet paper. With the rise of environmental awareness, more eco-friendly options are becoming available as well. It's important to be aware of the different toilet options available and proper etiquette when visiting or living in Japan.
