I went there on June 12th and 13th, 2024. I'm posting this because there wasn't much information about the preparations for getting to the island by boat.① When you arrive at the ferry terminal waiting area, unload your luggage.② Park your car at the nearby "Nonbiland Umashima 2nd Parking Lot".③ Use the cart at the pier to unload your luggage near the pier beyond the blue bridge.By the way, if you don't do this, the crew won't talk to you even if you wait anxiously in the waiting area. (Maybe it just happened to be me...)④When the ship arrives at the pier, call out to the crew and load your luggage onto the ship yourself. The crew won't help you.⑤Pay the fare to the crew in cash. The fare is 160 yen. Up to two pieces of baggage are free, but three or more pieces will be subject to additional transportation charges. In my case, I had 4 pieces of luggage and the additional fee was 120 yen.⑥Once you leave the port, it will take you 6 to 8 minutes to reach Mashima.⑦When you arrive at Mashima, you will unload your luggage yourself.⑧If you have made a reservation for a campsite, a cart with the name tag of the person who made the reservation will be prepared, so load your luggage on it and head to the campsite! Of course, this does not apply to those who have their own carry wagon.⑨ Returning is the reverse of the going.The campsite was a very pleasant grassy campsite, and the person managing it was very kind! Of course, there's also the ocean nearby, so if you're going to use this campsite, it might be a good idea to plan your own event and enjoy it! If the conditions are right, the sunset is also beautiful. Please be careful when using it during hot weather. In my experience, there are a lot of horseflies and mosquitoes. I didn't get bitten by a horsefly, but they do come close to me quite a bit. Mosquitoes are larger than the mosquitoes you usually see, and they attract quite a lot of people. It is a good idea to spray insect repellent around your tent and burn multiple mosquito coils. By the way, Onyanma-kun had no effect at all. Also, be careful with food and garbage. Stray cats come to scavenge for food and garbage. I was littered with garbage.Anyway, it's a good campsite, so enjoy it safely.
