TTT project aims to create a truly inclusive society inspired by the Olympic and Paralympic Games Tokyo 2020 through the installation of public toilets comfortable for all residents and visitors of Shibuya City, regardless of gender, age, or impairment.Anyone who has visited Shibuya has likely encountered one of these distinctive toilets, each with a memorable design. Established by sixteen prominent creators who agree with the aims of the project from the fields of architecture and design, the toilets boast eye-catching aesthetics that invite passersby to stop and take notice. After consultations between Shibuya City and The Nippon Foundation, who managed the establishment of the project, the toilets were strategically placed in high-traffic areas to promote awareness of an inclusive society through the power of design and creativity.
TTTs are designed based on the concept and surrounded environment of each space. They were constructed by Daiwa House Industry Co., Ltd. while TOTO Ltd. assisted with surveying and equipment proposals. All 17 locations completed in 2023 are equipped with at least one private universal toilet that can be used by anybody. These private rooms are available for use of people of all genders, including those with small children, people with buggies and wheelchair users. The lighting and layout are carefully considered to ensure safety and meet the users' needs.

Japanese toilets are a symbol of the country's renowned culture of hospitality. Visitors to Japan are often astounded by the pristine, well-maintained, public toilets that are easy and free to use. The toilet's thorough cleaning has recently gained international attention and attracted overseas visitors through films like PERFECT DAYS, which portrays the daily life of a TTT maintenance staff member.
TTT's toilets, managed by Shibuya City since April 1, 2024, are cleaned up to three times a day, compared to once a day for ordinary public toilets. The daily cleaning includes dry wipe down which makes it easier to keep dry and clean. Stains are also checked and removed. Periodic cleaning involves the removal of water stains, black stains and yellowing with special solvents to remove accumulated dirt. Special cleaning involves the cleaning of external walls, light fittings, ventilation fans and roofs. At monthly meetings, the involved parties review cleaning and inspection reports to improve maintenance. TTT really go above and beyond to raise awareness that everyone should use public toilets with care.
Since the installations of TTT, locals and visitors have expressed positive feedback, noting that the clean, well-lit, and beautifully designed buildings have transformed the atmosphere. Many are pleased with the ease of use and comfort provided. The presence of renowned architectural works also adds a cultural touch, while the safety of the facilities at night has made the community feel more secure. Visitors to Tokyo can explore Shibuya knowing that inclusive, clean, safe and comfortable toilets are always within reach.
