No, you do not need to bring your own toilet paper to Japan. In 2026, Japan remains world-renowned for its exceptionally clean and high-tech public restrooms. Almost every toilet—from those in high-end department stores and train stations to small convenience stores like 7-Eleven—is equipped with a "washlet" (bidet) system featuring heated seats, adjustable water sprays, and drying functions. Standard toilet paper is always provided for free and is designed to be flushed directly down the toilet, as Japan has a very advanced sewage system. In fact, carrying your own paper might be counterproductive, as thick, non-dissolvable tissues from other countries can cause clogs. The only rare exception might be in very remote hiking trails or ancient temples in rural areas where "squat toilets" are still used, but even then, most provide paper or have a small vending machine nearby for pocket tissues.
