It takes about 3 and a half hours to get there from Takeshiba by jet boat. You can go there by large boat or plane, so there are many options. Highlights include the starry sky, the transparent sea, and mountain climbing. Renting a bicycle is not recommended as the island is full of slopes. There are a limited number of rental cars available, and the rental car companies are often busy, so be sure to make a reservation before you go. Personally, I think it is better to go to ``Akasaki Promenade'' and ``Starry Sky''. On your way back from the Akasaki Promenade, we recommend stopping by Kozushima Onsen Recreation Center, the only hot spring facility on the island, to refresh yourself. This is located on the coast, and the open-air bath (mixed bathing suit required) built into the rocky area is very nice. About “Starry Sky” To be honest, you can see it well anywhere with few streets, but it seems that most people tend to see it from places labeled as ``observation decks''. One thing to keep in mind is that if you are with the people on the starry sky tour, they will use a laser to explain the constellations next to you, so many people may be interested. There's no end to it as I write about it, but you can enjoy it even for 1 night or 2 days. I highly recommend that you go at least once.

It is one of the Izu Seven Islands, and in mythology, it is said that the island was created by Kotoshironoshi, and the name changed from the island where the gods gathered to become Kozushima. There are several means of transportation from Tokyo, but if you want to enjoy your trip, we recommend traveling by large cruise ship. There is only one boat per day (departing at 10pm) and it takes 12 hours each way, but you can enjoy the cruise to the fullest. In recent years, it has been designated as a ``Dark Sky Island'' as a mecca for astronomical observation.

The incredible beauty of the sea. If you want to get around the island, we highly recommend a moped or a small motorcycle.We stayed at a guesthouse, but the sheets and pillowcases looked like they had been used, and we were disappointed by the age of the inn itself and the lack of cleanliness. I'm convinced that it can't be helped if it costs just under 4,000 yen and includes two meals. The island is a treasure trove of natural activities such as the sea, mountains, and rocky areas. We also enjoyed fishing from the breakwater. The result was only one fish, but I was very satisfied. We recommend a high-speed jet boat to Kurushima rather than the overnight ferry Salvia Maru ^_^

Superb

It was a stay of 2 nights and 3 days. As for the sea, it seems that it was a little muddy due to the typhoon, but I still thought it was beautiful (personally), so I would like to visit this place again if I have the chance. 1st photo: "Akasaki Promenade"...You can get there in about 15 minutes from the bus stop at Yotchare Center (near Kozu Port). Because it is surrounded by rocky areas, there is no sand floating around, and the water is highly transparent. There is also a diving board, and if you go a little deeper, you can see small fish and crabs on the reef where people can get off like a tide pool. 2nd photo: "Maehama Beach"...A beach that stretches right next to Kozu Port. It's a good place to play as there are lots of people and shops nearby, but when we went there, the waves were strong due to the typhoon, and the sand was flying around in the water, making it look muddy. It was a shame. When I talk to island residents, they say that they can usually see through the water very clearly. If sand gets into your swimsuit, you should use the coin shower located next to the store. 3rd photo: ``Fishing''...The photo seems to be of a fish called Ojisan. I went with a group of people who were not familiar with fishing at all, but we managed to catch some fish like this. The location is the embankment near Yocchare Center. You can often catch spiny lobsters, but be careful as individuals are apparently prohibited from using them for personal use due to local ordinances. 4th photo: ``About the food''...This photo is of the ``boiled set meal'' served at a facility called Yocchare Center near Kozu Port. There must have been other menu items such as ``Zukedon Set Meal'', ``Sashimi Set Meal'', ``Fish Curry Set Meal'', and ``Ginger Yaki Set Meal''. Although there are dining facilities on Kozushima, there are some that you can only go to if you make a reservation, so be sure to check them out. (It's probably okay to not do this here.)

180km from Tokyo, it is said to be an island where the gods gather. An island with highly transparent sea, white beaches, and a beautiful starry sky. [Kozushima] originates from the fact that in the past, it served as a base for gathering and consulting the gods in order to create the islands of Izu (in the old days, it was written as ``Kamizushima''). Groundwater is abundant. Spring water bubbles up from various places on the island, and it is considered one of the famous spring waters in Tokyo. The water quality and clarity of the sea is the best in Japan.

The first thing that surprised me when I got off the boat was how clean the sea was. I was surprised by the blue color, which could be mistaken for Okinawa. Also, I was touched by the kindness of the islanders, and I want to visit not only this time but many times, and if possible, I would like to move there...lol

It's a beautiful island and the islanders are kind, but the transportation system is weak. Buses are running, but they are not linked to the arrival times of ships or planes, and taxis are hard to find.

The sea is amazing and beautiful, the 🎣 is amazing, and the natural 🚰 is so delicious⭕

We traveled by Sarubia Maru for 12 hours each way and stayed for 2 nights and 3 days. Since the island is in a volcanic zone, the sea was extremely beautiful.
