Helios Brewery Factory Tour

Peninsula with an underwater observation tower, and a glass-bottom boat that leaves every 20 minutes. Free shuttle bus that looks like a tram.

Mid-island on the Western side.

Don't expect to find the castle as it was in the 14th century, but enjoy the nice walk to the top of the hill. The park of the Nago castle is on the Top 100 list of cherry tree flower viewing (hanami) spots of Japan, and the only place in the Okinawa prefecture on the list.

Kitschy pineapple-themed park. A short but entertaining ride on an automated golf cart gives you some history about pineapple cultivation, dropping you off in a shopping center where all the products are either pineapple-themed or contain pineapple (or both!) Worth a stop if you're in the area and you like pineapple.

The beach itself is nothing special, but the snorkeling here is some of the best on the island, with plenty of fish and vibrant coral. There's a staircase down at the right side of the Okashi Goten shop, but it closes at 18:00 sharp.
