An interesting museum on the history of the automobile industry, displaying many cars from the earliest up to just prior to present day (circa 2010s), with models produced by US, European and Japanese manufacturers. It exhibits the cars chronologically, so it's very interesting to see how the car designs change over time, with European and US manufacturers dominating the early years. There's a section showing how Japan entered and rose in the automobile industry, the government regulations that supported this, the Japanese entrepreneurs behind it and stats on the overall sales growth of the industry.

It is pretty much exclusively history, placing Japan's part in context of the history of the global automobile industry. There's no exhibits on the science or technology of automobiles or their manufacturing. It also focuses exclusively on the consumer models and while sports models are on display, there's very little mention of motorsport vehicles specifically.

What I liked about the museum was the reasonably priced entry of 1,200 yen for standard adult ticket, and the main showrooms can be viewed in 2-3 hours, so no fear of missing out or needing to revisit. There's a cultural showroom that I didn't get to see so I'd add an hour for that. Also the descriptions are all in English (as well as Japanese) plus there's an audio guide for Android and Apple smartphones

Less positive things I'd mention is that there are no interactive or child friendly exhibits in the main showrooms, so young children may get bored, but there are toy cars on display. Also the cultural showroom may be of some interest to children, with toy cars and manga, but I didn't get to see this. I might liked to have seen more on the technology and manufacturing process of automobiles, as this interests me a little more than history, but still interesting all the same.

In summary, I'd describe it as a museum of the history of the automobile industry in Japan and the world, combined with a car showroom.
