got a quick question, you see the 600 yen... do you mean you pay like 18000yen per month so it comes out to be 600 per day OR is it how much it costs without contract so u can just pay that much each time you go?

are there many pool halls? i was wondering if i should bring my cue with me.

They exist but not as popular as back home (UK)... I'm guessing the space needed for tables is a bit of a problem for a lot of bars outside Roppongi lol

when i went to japan, we walked A LOT due to that was one of our only ways of transportation...besides trains and taxis which we used taxis very rarely. One way to get fit, go to Miyajima Island and climb up Mt. Mizen. DO NOT take the rail sky car thingy. You'll get a heck of a workout going up that thing and and its even more tedious going DOWN. Walk a lot, say, go to Harajuku, you'll get a good walk without even realizing, just make sure you go to the shrine(?)temple(?).

Yeah, darts is a lot more popular than billards. Most places are soft tip. So if you've got darts be sure to bring'em.

Each day you go is probably what he means, but 18000 yen a month for a popular gym sounds almost reasonable. The cheapest monthly gym in my city is about 10,000 yen a month and the highest is around 20,000. Which is why I use the community center for 200 yen a day and have dumbells at my apartment.
