Anata no Warehouse あなたのウェアハウス is a multi-storey game center with Kowloon Walled City decor pretty close to Kawasaki Station. If you also found this place on Atlas Obscura, it looks just like the photos, except you're not allowed to take photos inside. It has arcade games, darts, and billiard. The cool Kowloon Walled City decor is just on the one side and most of the game center bit is just "normal". Most games are just 100 yen. You have to be 18 to enter.
