Hello Maru, and welcome to the Forum.
If you are in Tokyo, then what a fantastic position to be in... you get the pick of the bunch!
First bit of advice from me would be NOT to fall in love with the first NSR you look at! It's easily done!!
Secondly, I would say buy the most standard bike you can find! It will be tempting to get a bike with race pipes and rear-sets etc., but the less modifications it has, the less likely it is to have been fiddled with. Getting parts in Japan is a piece of cake, so you can always modify it later on.
Not sure how it works buying from shops in Japan, but you can usually get a 3 or 6 month warranty of sorts in the UK on a used bike. The longer the available warranty is usually a sign of how confident the seller is! If they only want to give you 30 days, then be a little suspicious! When I bought mine, the importer gave me 3 months free, and offered a dirt cheap +6 month (9 months in total) option, and a more expensive +9 months option.
Low mileage is key if this is a new venture for you. Try to get something with up to 20,000 kms on it. That should see you with another good 20,000+ kms at least on the crank with a standard motor... probably double that. The crank is the most expensive part of the bike to replace.
Most bikes will have been crashed at some point! Look for all the usual signs. Scraped handlebar ends, scraped levers, scraped footrests, scraped exhaust cans etc. They can all be cleaned up easily for minor "low sides", but always leave some evidence.
Good condition original plastic is worth more than ANY aftermarket stuff, regardless of what colours it's painted in, and how good the finish is!
Regardless of what the seller tells you, I would take it to a Honda dealer and get the top-end serviced. New pistons and rings. I doubt it's going to cost too much in Japan.
I'm sure others will have some more ideas for you. There are also a couple of Forum Members in Japan that can offer up some more localised advice too.
