mice roppongi and hairdressers

I spent my first proper weekend visiting the crazy sights of Shinjuku which is one of the busiest areas of Tokyo and also where my Japanese friend lives. after finally managing to leave the station and find my friends (it has a confusingly large number of exits and floors and areas and people and signs and noises) we had a good tourist stroll around before heading to Roppongi (I love that name) where the nightlife of Tokyo can be found. We went up Roppongi tower which has 52 floors and the lift gives you motion sickness and makes your ears pop! but the view was well worth it. just as the sun was setting you get an amazing view over Tokyo with all the dizzy lights from bars, sushi restaurants, cars, ferris wheels, skyscrapers and all the rest. on a clear day you can apparently see as far as Mount Fuji from that tower which must be impressive.
There was a really cool ancient to modern art exhibition of China on at the same time. It was so refreshing to see and apreciate art again having finished the formality of studying it!
We ate in a restaurant in the same building and at one point my friend Hiro screamed- there was a mouse running around the floor under the tables. The whole place exploded it was so funny to see! Eventually the offender was whacked over the head by one of the chefs and calm was restored. Still didnt get any money off our meal!!!
I have done the compulsory thing of getting on an express train instead of a local one and for some reason my Japanese wasnt good enough to negotiate the best way to proceed after that! I got home after 1 & 1/2 hours when it should have taken me 25 minutes!! It had to happen sometime! At least the trains here are always dead on time - even if there are a confusing array of choices (local, rapid, private, JR, subway, overground). And they are all sparklingly clean. I have even started to fit in with the locals as I catch a few forty winks on my way to work. (Everybody is asleep on the trains here!)
Finally- one of the many quirks of this place is that hairdressers (of which there seem to be thousands) stay open really late but in the absense of real customers they crimp and cut and curl and perm plastic models hair in the windows. Does that happen at home or is that a bit bizarre!!
