The maximum speed of the Shinkansen during commercial service is 300 km/h (187 mph), but they have to slow down in urban areas due to curved tracks and noise issue. You can see the bullet trains traveling between buildings quite slowly in those areas.
Yurakucho, just south of Tokyo Station, is one of my favorite places to watch the trains going by. When a train passes by, you can also see its reflection on the mirror wall of a building.
