I enjoyed a game in that very ballpark back in '09; Brother Elephants vs. Team 7-11.
Some odd names, but the Pirate style uniforms (though navy, and not black) were cool. Nearly all team names were corporate in nature, and "Brother Elephants" was the product of two hotel chains that had merged and settled on this curious name lol. The logo on the Elephants cap is Taiwan's national symbol, a lotus flower, and the league in '09, as I recall, consisted only of 6 or 8 teams. Neighboring fans had explained that in recent times, a huge gambling scandal had decimated the league and forced roughly half of Taiwan's teams to fold. Not sure if they've since recovered.
Not unlike Japanese baseball, each side has an official cheer leading squad, replete with drums, cymbals, microphones and very pretty Taiwanese pompom girls, as well as a dragon-like caricature or two. In addition, there were two box offices; right side/left side of the park, and from either, you purchased from the side from which you wished to sit. So, 3rd base side fans were dressed mostly in orange, while first base side fans were adorned in the Elephants navy and yellow.
A very different experience, indeed. Definitely whet my appetite to go and see Japanese baseball next time I'm in the area. Definitely plan on donning my Reds gear for the Hiroshima Carp.
