You should try to avoid Poli-kou heavens like around the Diet Hall and Jiminto-honbu. ... I have to commute through the area. Pretty, but you get in within 50cm of police people. They "can" stop you if they want to, so it is safer if you have less thing for them to stop you with.

You aren't likely to get fined. But you get lectures ... boring ones. I mean they gave me 30min lecture on having my bike registered. You would be better off spending that time heading over to Blue Lug in Shinjuku (15-20min? from center city). Im too noob for that place though.
