Communications Museum, Communications museum in Ōtemachi, Japan.
The Communications Museum stands inside the Teishin Building in Ōtemachi, a business district in central Tokyo, and displays devices from different phases of telecommunications history across several floors. The exhibition spaces are organized by theme, guiding visitors from simple telegraph machines to modern computing systems.
The building served as a central location for managing Japanese postal and telegraph services from the early twentieth century onward. Later, the museum was established here to document the development of communication technology in Japan.
The collection reflects how Japanese families and businesses adopted new forms of communication over the decades, showing everyday tools that once connected people across cities and islands. Many objects come from private households and bear signs of their former use.
The entrance is a short walk from Kanda Station, and the facility opens on weekdays from late morning to early evening. Staff members offer explanations in Japanese and occasionally in English, and information sheets are available at the entrance.
Visitors are allowed to handle and try out many of the historical devices themselves, which is rare for museums of this kind. Staff members provide instructions on how to operate old typewriters, cameras, or early computing machines.
