Nice views of city and harbor
Like: Nice place to relax and have a beer with a great view. Beer out of the vending machine was 280 yen (which is pretty cheap for a tourist attraction). Free telescopes about every 50 meters on the way to the observatory. Clean restrooms, gift shop and snack bar at the observatory.
Dislike: The bridge is a little shakey but safe. Bus ride there is long with a lot of stops
