The boat is very stable and has three floors. The lower two floors are indoors and have sofas where you can enjoy the scenery through the glass windows. The third floor is plywood, and the upper half floor is similar to an observation deck. The wind was so strong that it made everyone feel stupid, but the boat was as steady as a mountain and did not rock at all. The wind was so strong that my face was crooked when I got off the boat, so remember to wear a mask. But the scenery is worth it, really beautiful. There are multi-language broadcasts introducing the Kujuku Islands along the way, and the captain even demonstrates a 180-degree drift in the narrow bay to show off his excellent boating skills. The water is so clear that you can see jellyfish. The whole journey takes about 50 minutes. Coinciding with the winter oyster roasting festival, 400 barbecue grills are provided on the lawn for visitors to roast oysters on site. The oysters are very fresh, some are bigger than the palm of your hand, and 1,000 yen for 1kg is a good deal. There are also other seafood and snacks. When the weather is nice, it’s a great experience to eat grilled oysters under the sun and the sea breeze!
