I think the one in Round 1 was quite huge as well. Round 1 is a famous amusement complex with Bowling, Karaoke, Coinpushers, lots of games,....
It is a chain and exist in many Japanese cities. If my memory doesnt trick me, than there was one in Nagoya between the station and the futuristic looking buliding in the city (was it a bus terminal?).
If you ask some young Japanese where Round 1 is they will know (you will maybe have to write it down).
I can also recommend the "Spo.cha" inside Round 1 (not sure if nagoya´s got one) if you are going with a few people. You pay and hourly rate and can play unlimited Videogames, Soccer, batting,.... The one i was in koriyama had alot of choice, even shooting Arrows and playing golf.
