I went to the Hiroshima Carp website and read the basic visitor info. I also stumbled across this: http://www.japantimes.co.jp/sports/2013/09/14/baseball/lessons-on-ballpark-seating-etiquette-for-japanese-baseball/
Anyway, anything in particular ya'll think I should be prepared for? If it makes a difference, I have unreserved seats and that section seems to encompass both left and right sides of the field.
Thanks for the info.
