Museum of Science, TUS, Science history museum in Kagurazaka, Japan

The Museum of Science in Kagurazaka displays scientific instruments, documents, and models that trace the path of research and technological progress. The exhibitions show how scientific practices and discoveries evolved across different periods.

The museum was built in November 1991 for the 110th anniversary of Tokyo University of Science. Its construction was funded by a donation of 1.35 billion yen from Futamura Fukyu, founder of Futamura Chemical Industries, who graduated from the Tokyo Physics School's chemistry department in December 1941; a bronze statue of him stands in the first-floor entrance hall. The building reproduces the two-storey wooden schoolhouse the Tokyo Physics School, the university's predecessor, occupied in Kagurazaka from 1906.

The collection began with abacus and wasan texts from the Edo period and continues through sangi counting rods, soroban, slide rules, Tiger-brand mechanical calculators, the parametron-based FACOM 201, desktop electronic calculators and early personal computers such as the Apple II, PC-8001 and BASIC Master. In the physics school corner, 65 wooden polyhedron models cut by graduate and later lecturer Tamekichi Hishida (1868–1943) show Meiji-era polyhedron research and were also valued as sculpture. The Edison corner holds carbon bulbs and a phonograph from the Meiji period; the bulb can be lit at low voltage.

The museum sits near JR Iidabashi Station West Exit and the nearby metro station, making it accessible on foot from either entrance. Visitors can easily orient themselves using these two transport hubs as reference points.

The building reproduces the wooden two-storey schoolhouse built in Kagurazaka in 1906 for the Tokyo Physics School, the predecessor of Tokyo University of Science. The reconstruction was funded by a donation of 1.35 billion yen from Tomihisa Futamura, a 1941 graduate of the school's chemistry department, after whom the building is also called the Futamura Memorial Hall; his bronze statue stands in the ground-floor entrance hall.
