It takes about an hour to walk under the observation deck of the Kiro mountain observatory overlooking the Kurushima Bridge. Of course, the scenery is good from the middle, so walking is not boring. Try getting a passing car and getting on it. There are many kind people Japanese cars are weak sunting, so you can ask them to meet the passing drivers. Or you can rent electric bikes downstairs. It's a bit difficult to go by bike because there are many uphills. It is recommended to go up in time for sunset.
