well, you can find IIDX in most of the game centers in japan. game centers are not hard to find. inside shopping malls, on street malls, inside batting centers, etc. 1 in 2 game centers have otoge (music games). u dont need to go to ikebukuro to play IIDX, chiba itself has lots of IIDXs. good luck in finding one.
dont forget to get an e-amusement pass so that u can keep track of your records. better have it than none.
