thing about japanese arcade scene is you have to pick the right arcade for each game scene and your level.
specially popular games like SF4 or maybe BB, if you go to mecca of a perticular game, you may have hard time winning and burning your cash quick.
you may want to go to 2nd tier arcade where you find enough people playing but not filled with top players to get your money's worth time and experience.
if you are in country side, well if you can find scene for your game, or if you have access to arcade in reasonable distance, you are lucky.
