Firstly: There is an app you can download which gives information on the museum exhibits for non-Japanese speakers, I would advise to download this before you go. I am a massive Hanshin Tigers fan, and after being Tokyo a few times I finally made it to Osaka. Of course, my first point of call was Koshien. The museum is on the South side of the stadium and I visited the museum twice during my trip. The first time I just viewed the museum, the second I also did one of the stadium tours. The museum entry fee was 600yen. When I booked the stadium tour it was 1500yen and this included the entry fee also, so was only 900yen for a wonderful tour. The museum is split into 2 sections: History of the Japan High School National Baseball Tournament and history of the Hanshin Tigers. There is also a chance for you to go outside where you are below the scoreboard and can look across the pitch, this was the first time I ever witnessed the pitch and legendary scoreboard with my own eyes and it took my breathe away. The exhibits contain many historical artifacts such as uniforms, balls, caps, pennants and video displays. There is also a VR experience which I did not partake in. At the entrance to the museum there is a board that had various times for a tour, as I understand there are different tours and on game days it is even possible to watch the players warm up. My tour took us through the 3rd base (Visiting team) bullpen, locker room and dugout, so go got amazing views of the field. The staff were very friendly and welcoming, however only spoke Japanese. You will be given a handout with all the information the guides are speaking in your chosen language. There are opportunities to take photographs in certain areas wearing Hanshin Tigers apparel (If you are not already wearing any) and the guides are very happy to take a picture of yourself for you. At the end of the tour I was given a Museum of Koshien Stadium ticket holder which I Was very happy with especially as I Was going a few baseball games it came in very handy and a great souvenir. Upon museum exit, there is a Museum shop that contains not only Tigers merchandise but a few goods for Koshien stadium and limited goods for other pro baseball teams.
