The Space 11 Darvish Museum in Kobe opened today at 11:11am. About 100 items are on display, including a number of life-size figures and a batting game where you can face a digitized Yu Darvish. Admission is 1,000 yen for adults, 600 yen for junior high and high school students, and 300 yen for elementary school students. Anyone younger than that gets in free.
Asahi Shimbun has also posted a video that includes some footage from inside the museum.
