Yes, public toilets in Japan are almost universally free to use and are celebrated for being some of the cleanest and most technologically advanced in the world. You can find them in train stations, department stores, parks, and even most convenience stores like 7-Eleven or Lawson. These restrooms often feature Washlets (bidet seats) with heated seats, adjustable water sprays, and "Otohime" (sound princess) buttons that play artificial flushing sounds for privacy. Unlike in many European cities where a small coin fee is common, the Japanese government and private businesses view accessible, free restrooms as a fundamental part of public hospitality and hygiene. Most are well-stocked with toilet paper, though carrying a small pack of tissues is still a common local habit just in case. They are also highly accessible, with many "Multipurpose" toilets designed for families and individuals with disabilities.
