Here are some pics of arcades we found in Ikebukuro
Game Park Ramble Plaza
This arcade had a good selection of vintage titles, including several Mahjong cabs. Check out the awesome Cyber Lead cabinets!
Mostly LCD cabs featuring Super Street Fighter IV: Arcade Edition and Tekken 6: Bloodline Rebellion, very popular.
A nice mix of LCD and CRT cabs. Has a small retro section and a range of Cave shooters as well as the latest fighting games. Unsurprisingly, a large number of awesome looking Sega Lindbergh cabs featuring Virtua Fighter 5: Final Showdown.
Playland Las Vegas
A small arcade featurning some vintage titles as well as the latest fighting games.
An arcade featuring the latest dedicated machines. The first time I got to play the awesome Darius Burst: Another Chronicle.
