Yes, and this is a big problem for me. I buy a game, play it for 2 or 3 hours, then I don't have time to play more. Busy life, etc. But, then the next big game comes out and I need to have it. Rinse, repeat.
Go out partying all night at one of the club districts, and enjoy the part of the night where the trains stop running, teens and drunken salarymen wander the streets like zombies, and things just get eerily quiet. Then eat at a Yoshinoya to nurse your hangover.
Also, stay the fuck away from Kabukicho. You don't want anything they are selling. Trust me.
