I went to Mitsubishi Minatomirai Industrial Museum with my son. It is located in the water front district of Yokohama city. Its admission fee is 500 yen ($4.95 €3.57), 300 yen for Junior high/High school students, 200 yen for elementary school students. The museum displays technologies about aerospace, ocean, transportation, daily life, environment, and energy which Mitsubishi Heavy Industries, Ltd. deals with. The museum used to exhibit technologies for nuclear plants extensively. But after the accident at Fukushima nuclear power station, the museum withdrew nuclear issues and replaced them with other technology exhibits.
