Fun to visit the 'Sea candle' (a lighthouse with observation deck) and look out over the sea. You'll pay 500 yen per adult (there are ticket machines at the base) and this gets you access to the observation deck via a lift. Depending on the day of the week and time, you may well have to queue, but as the lift comes and goes every few minutes the lines moves forward regularly. The observation deck is not large but you can walk all the way around it. There are a few benches to sit on while you take in the salt air and the view and some coin-operated binoculars. When you are done you take the lift down again - although there is an external staircase that was open when we visited. At the base there is an outdoor deck with a small stand serving drinks, chairs, and sofas, and also (just next to the ticket machines) a gift shop (of course).
