We don't use cars, but public transportation(Walking Tour).

The Cup Noodles Museum and Kirin Beer Factory are very popular. So reservations are required as soon as possible.
We can also take you to the Yamashita Park, the observatory, the Red Brick Warehouse and Chinatown, which are popular on regular tours, if you want.
I recommend simple Japanese culture Experience(15minutes by train).
And Sankeien(Japanese style garden) , a bit far from the downtown(45minutes by bus) though.

Yokohama was founded with the end of the Samurai government's isolationist policy. So Yokohama is young (170 years old) compared to other cities in Japan. Yokohama served as a gateway for modern Western culture. Then, Yokohama has grown up. The current population (3.8 million) ranks first among Japanese cities.

Don't hesitate to tell us your interests and wishes. For example, reduce the distance you walk because your knees and back hurt.
You might want to drink a matcha latte, or etc.
