Designed by architects including Tadao Ando and Kengo Kuma, the Tokyo Toilet project forms the backdrop for the Oscar-nominated film Perfect Days. Here, Dezeen rounds up all 17 facilities.

The Tokyo Toilet project brings together 17 public toilets in the city's Shibuya district, created by architects and designers over the past six years.

Commissioned by The Nippon Foundation as "a symbol of Japan's world-renowned hospitality culture", the unique facilities are now the subject of Perfect Days, an Oscar-nominated film by German filmmaker Wim Wenders that follows the daily life of a local janitor who cleans the toilets – played by Kōji Yakusho.

Following the movie's release and in the run-up to the 2024 Oscars ceremony on 10 March, Dezeen has rounded up all 17 of the Tokyo Toilets, which their designers say were created with safety, cleanliness and inclusivity in mind.

Toilet, Higashi Sanchome, by Nao Tamura

Designer Nao Tamura took cues from Origata – the traditional Japanese gift-wrapping method and a nod to hospitality – when creating this red public toilet on a triangular plot in the city's Higashi Sanchome area.

The structure, which launched the Tokyo Toilet project, features a wheelchair-accessible bathroom and separate male and female toilets.

Tamura used bright red for the metal shell to make the block visible and project a "sense of urgency".

Toilet, Yoyogi Fukamachi Mini Park, by Shigeru Ban

Pritzker Prize-winning architect Shigeru Ban designed a pair of coloured glass toilets with transparent walls to enable those approaching to check whether they are in use.

When occupied, the toilets' tinted facades become opaque for privacy. One of the rectilinear structures was clad in shades of orange, pink and purple and is located in the city's Yoyogi Fukamachi Mini Park.

Squid Toilet, Ebisu East Park, by Fumihiko Maki

Dubbed "Squid Toilet", this public restroom was designed by Pritzker Prize-winning architect Fumihiko Maki.

The four-volume structure was built to be used as a place for people to rest as well as a toilet and features a compact courtyard at its centre, which is shaded by a thin, curved white roof.

Located in Ebisu East Park – known as "Octopus Park" for its octopus-shaped red slide – the toilet was created to emphasise the area's existing playfulness.

Modern Kawaya, Ebisu Park, by Wonderwall

Prehistoric Japanese huts served as the starting point for this public toilet in Ebisu Park, created by interior design studio Wonderwall.

A maze of 15 board-marked concrete walls encloses the facility, which references Japan's primitive kawaya huts that were historically used as toilets.

Male and female toilets, as well as a unisex cubicle with facilities for baby-changing and disabled users, were included in the design.

Amayadori, Jingu-Dori Park, by Tadao Ando

Pritzker Prize-winning architect Ando wrapped this circular public toilet in a wall made from vertical metal louvres, which allow for privacy but also air circulation.

An angled, overhanging roof shelters the multi-cubicled structure that is nestled among cherry trees in the city's Jingu-Dori Park.

"It was vital for me to make a space that was comfortable and safe," explained Ando, who called the toilet Amayadori – meaning rain shelter in Japanese.

Andon, Nishihara Itchome Park, by Takenosuke Sakakura

Three unisex toilets that glow after dark were designed by architect Takenosuke Sakakura, who also imprinted tree patterns on the structures' frosted glass facades.

Named Andon after the Japanese word for lantern, the block was created to provide safe and inviting facilities for nighttime users and "improve the image of not only the restroom but the entire park," said Sakakura.

Toilet, Jingumae, by Nigo

Sandwiched between high-rise buildings, this public toilet was created by fashion designer Nigo to stand out.

The playful restroom was made in the shape of a small house with a red-pitched roof, blue-framed windows and three chimney-style elements.

Partly surrounded by a white picket fence, the toilet design takes cues from a former Tokyo housing development constructed by the United States Armed Forces after the second world war.

Toilet, Yoyogi-Hachiman, by Toyo Ito

A trio of mushroom-like toilets form Pritzker Prize-winning architect Toyo Ito's contribution to the city-wide project.

The facility, which replaced a former toilet block positioned at the bottom of a flight of steps leading up to the Shibuya district's Yoyogi Hachimangu shrine, references mushrooms that grow in the nearby forest.

Ito broke the toilets into three separate spaces to try and make the facility a safe place for all of its users.

Five toilet blocks, which were not delineated by gender, were inserted into the bright and clean-looking facility. The toilet was positioned outside Tokyo's bustling Ebusi Station as a "neighbourhood symbol," explained Sato.

Toilet, Hatagaya, by Miles Pennington and DLX Design Lab

Designer Miles Pennington and the University of Tokyo's DLX Design Lab collaborated to create a toilet that can be used as an exhibition space, cinema, pop-up kiosk, information centre or public meeting place.

A male toilet and unisex cubicles were arranged around a large covered area. Within the block, there are expansive white walls designed to hang artworks or have films projected onto them.

"This is a community space that happens to have toilets too," said Pennington, who is a professor of design-led innovation at the university.

Toilet, Nishisando, by Sou Fujimoto 

Architect Sou Fujimoto designed the final instalment of the Tokyo Toilet project in the city's downtown area.

Characterised by an elongated communal handwashing area with different height taps, the all-white facility's sinuous curves were created to resemble an oversized sink.

Fujimoto's structure contains toilets for men, women and children that are connected by an open-air corridor so that "everyone from children to older people can wash their hands within this vessel," said the architect.
