If want other "cage" ask local
Which "batting center" best? recommend.
Most Japanese cannot understand(not using) "cage" meaning.
Younger often using(calling) shorter "baccen(bassen)".


This cage in Fukuoka[Kyushu](not Hokkaido)
but fastest max230km/h machine in the world(?) pretty crazy :D

230km/h, wow, that's kinda scary! I can't imagine you can even see the ball.

I remember a place call "Sluggers" in the Susukino area. They had indoor batting cages.
