About Yokosuka Route Museum

A “museum” with “routes” connecting together the history, culture, and natural environment of Yokosuka

The Yokosuka Route Museum is connected together by “routes” leading between places to enjoy Yokosuka’s abundant nature and notable historical and cultural sites scattered around this city.
The whole city is thus construed as a new sort of a “museum” that connects abundant nature with the interesting culture and history of Yokosuka from the time when Japan opened up to the world and entered modernity.

The Yokosuka Route Museum covers a wide variety of locations beginning with Yokosuka Iron Works, which played a central role in the history of Japan’s modernization since the country opened up to the world after Perry’s arrival.
Novel technologies and culture spread all over Japan from Yokosuka Iron Works during this time. In addition to such historical aspects, the Museum introduces the natural environment of Yokosuka, beginning with the abundant greenery and the “two seas” that are Tokyo Bay and Sagami Bay.
Please enjoy the abundant nature of Yokosuka while exploring historical sites that tell the story of the beginning of modernization of Japan.

Please feel the history of the beginning of the modernization Japan and experience the “retro-modern” Yokosuka.
