A Japan Women's Baseball League Primer - My First Game in Sendai
Food is pretty limited. At the Sendai event, there was a crepe cart and some other food from a cart, as well as drinks (including beer). You could probably bring your own too, though I'd advise bringing it from downtown Sendai. There isn't much selection on the way, though there is a major cross street on the walk from the station which could still have a 7-Eleven or other convenience store.
As for souvenirs, if you can navigate the Japanese website you'll see everything they have for sale - essentially team goods and an annual program/yearbook. I'd like to get a hat and jersey... There's also a custom baseball card printer on-site - you can get cards made of yourself which you then trade with the players after the game. That's something I have to do next year.
During Victoria Series games, West and South become All West Japan, and North and East become All East Japan.
Through 2012, the league was called the Girls Professional Baseball League, but became JWBL in 2013 with the new format.
I'm a little disappointed in myself, because I had planned to go to more games last year, but I only made it to two dates. In 2014, I expect to go to a few more events. I'd like to get my own cards made to trade with the players and hopefully collect some autographs too! They haven't announced their schedule yet, but as long as they play in the Tokyo area while I'm in town, I'll be sure to catch a few games.
