Read my post about my Hiroshima Toyo Carp/Mazda Stadium experience over at Chaos and Kanji!
On a related note, I picked up some souvenirs from the ballpark.
With space at a premium in my suitcase, I stuck to tiny knickknacks that I thought were fairly unique. Japanese seem to love objects they can attach to their phone, bag, and keychain. Here is a small piece of wood with artwork featuring the mascot, Slyly.
Not happy with just that, I went for the mini batting helmet dangle.
While it isn't much, I enjoy my souvenirs of the Carp. The carp is basically Hiroshima's city symbol, and I'm surprised I didn't find anything I like with an actual carp on it!
