If you're in Tokyo and have money to spend, I strongly suggest you catch a gig at the Blue Note Tokyo. Excellent acts from all around the world come to show their stuff and thrill the crowd. Gipsy Kings, Thelonious Monk, Diane Schuur, Dionne Warwick, Joe Sample, the list just keeps going on. The food and drink selection isn't too bad either (for a jazz bar.) Get 4 of your friends and GO!
