Hamamatsu Science Museum, Science museum in Naka-ku, Hamamatsu, Japan.

The Hamamatsu Science Museum is a science museum whose permanent exhibition is divided into zones on nature, sound, light, force and space. Architect Mitsuru Senda designed the building around a looping "play-ring" structure, and colourful exposed pipes let visitors read the building services. Local manufacturers have lent or deposited real objects and materials for display.

The museum opened on 1 May 1986 as a replacement for the Hamamatsu City Children's Center, and it was the first science museum designed by architect Mitsuru Senda, whose "play-ring" structure runs through the building. It closed at the end of March 2018 for renovation and reopened on 6 July 2019 under the nickname Mirai-ra.

The museum displays technologies from major regional companies such as Yamaha, Suzuki, Honda, and Roland. Visitors can see how these firms have shaped the area's economy and what innovations have emerged locally.

The museum is about five minutes on foot east of Hamamatsu Station. The site was once a train stabling yard for the old station, and a guard under the Shinkansen viaduct that carried the former siding remains on the west side.

The planetarium's projector, Chiron III Hybrid, was custom-designed in Mikabi mandarin orange colour for the March 2022 renewal. The museum stands on the former Hamamatsu Station rolling-stock siding; west of the site, a guard under the Shinkansen viaduct marks the old branch line. The manga Ichigo Mashimaro by Hamamatsu-born Barasui includes an episode set around the museum.
