Why you should experience Gas Science Museum in Tokyo, Japan.
Gas Science Museum is an engaging educational institution where Toyosu 6-chome's industrial heritage, waterfront redevelopment, environmental architecture and energy infrastructure converge on ground long associated with Tokyo Gas.
Set along Toyosu Park near Harumi-dori and just steps from Toyosu Station, the museum occupies a low-rise structure whose sweeping grass-covered roof descends toward the surrounding waterfront landscape. Nikken Sekkei and Tokyo Gas Urban Development designed the 6,400-square-meter building, completed in January 2006 as an architectural component of Toyosu's transition from industrial ground into a public waterfront district. The roof functions as an accessible lawn rising above exhibition floors arranged beneath its broad incline, allowing the building to merge physically with the adjoining park system. The result is a science museum whose architecture converts an energy company's former industrial territory into public green space, making Toyosu's extraordinary physical reinvention visible before the exhibitions even begin.
What you should know about Gas Science Museum.
Gas Science Museum is best known for carrying forward an educational project Tokyo Gas established as part of its centennial celebrations in 1986. The original Gas Science Museum opened on March 17 of that year inside the company's Toyosu factory grounds, following a groundbreaking ceremony held in December 1984. Tokyo Gas had begun operating its Toyosu factory in 1956, placing the museum inside a district already deeply connected with metropolitan energy production. The first institution concentrated on explaining city gas to school groups and Tokyo Gas customers through exhibits tied to household energy and gas infrastructure. Participation became unusually extensive among Tokyo schools. By 2006, Tokyo Gas stated that roughly 90 percent of elementary schools in the metropolitan area had visited at least once. Cumulative attendance exceeded two million in January 2006. Tokyo's Toyosu land-readjustment project then required the original institution to leave its site, and the twenty-year-old museum closed on March 24. The successor opened elsewhere in Toyosu on June 2 under the name Gasutenani, preserving the educational mission on a district undergoing wholesale redevelopment.
Successive exhibition changes expanded that mission far beyond the institution's original concentration on city gas. The name Gasutenani was devised around the Japanese question βGasγ£γ¦γͺγγ«?β and the progression from curiosity toward understanding became central to the museum's educational program. Puka, Poka and Pika joined the 2006 institution as characters associated respectively with gas and flame, heat and gas-generated electricity. Attendance reached 100,000 within five months, 1.1 million on the fourth anniversary in June 2010 and two million in October 2013. Tokyo Gas incorporated portions of its former Yokohama Environment and Energy Museum into a comprehensive second-floor renovation in April 2014, broadening exhibitions devoted to global environmental issues and relationships between energy and human activity. A second major renewal followed in October 2019 under a program centered on energy, future society and creative problem solving; approximately 3.4 million admissions had accumulated by that point. The museum crossed four million admissions in February 2024. Tokyo Gas announced in November 2025 that the institution will close on September 23, 2026, with its next-generation educational work transferring to the Tokyo Gas Next Generation Education Center and the existing building slated for renovation toward a new public-serving purpose. A final five-day program from September 19 through September 23 will close a forty-year institutional lineage extending across both Toyosu museums.
How to fold Gas Science Museum into your trip.
Gas Science Museum works as the anchor for a daytime progression through a waterfront civic complex, an immersive digital-art institution and the wholesale market that transferred Tokyo's historic seafood trade onto Toyosu's reclaimed ground.
Begin at Toyosu Civic Center, completed in 2015 as a 15,604-square-meter public complex designed by Shunichi Sugiyama, Akira Kono and Atsuhiko Amakasu of Nikken Sekkei. Twelve above-ground floors combine the Toyosu Cultural Center, Toyosu Library and civic functions inside a terraced structure conceived around soil, greenery and extensive use of timber. Larch, cedar, oak, ash and Japanese cypress appear across exterior louvers, mullions and interior elements, bringing a deliberately tactile architectural style into a district formerly occupied by shipyards and power infrastructure. Continue to teamLab Planets TOKYO, which debuted in Toyosu on July 7, 2018 after teamLab developed the project from its 47-day DMM.Planets presentation in Odaiba two years earlier. The original Toyosu project occupied approximately 10,000 square meters and assembled immense installations including The Infinite Crystal Universe, Floating in the Falling Universe of Flowers and Drawing on the Water Surface Created by the Dance of Koi and People - Infinity. A January 2025 expansion introduced additional works and renewed spaces, extending a project initially conceived for a limited two-year run through the end of 2027. Conclude at Toyosu Market, the successor to a wholesale institution whose roots stretch through Nihonbashi and the 1935 Tsukiji Market. Tokyo selected Toyosu for relocation in 2001 as aging Tsukiji facilities demanded replacement, and the new market began operations on October 11, 2018. Its 407,000-square-meter site separates seafood wholesale, intermediate wholesale and fruit-and-vegetable operations within a purpose-built complex equipped for controlled logistics and modern food-safety requirements. The progression moves from civic architecture created for Toyosu's growing residential population through digital art occupying the redeveloped waterfront into the enormous wholesale institution that transferred one of Tokyo's oldest commercial systems onto former industrial land.
