This is a half-day plan for two introductory dives in northern Okinawa. In the northern part of the island, we will dive at Minna Island, Sesoko Island, and Motobu Town. We will guide you to the best point for the day's sea conditions and conditions, from a vast coral reef point, a point with beautiful sparkling sand, a point where you can meet many Nemo, a point where you can meet many garden eels, and a powerful cliff point. Since we will go to two points, you can enjoy different scenery and colorful tropical fish, as if you were in an aquarium. In addition, since it is a boat dive, you will not have to carry heavy equipment on land for a short time, so you will not waste your energy! Since it is a course that spends half a day on a boat, you can enjoy the feeling of cruising while being soothed by the "emerald blue" sea. 《The charm of northern Okinawa》◇Minna Island has high transparency, and the coral reef colonies in the shallows are particularly beautiful in Okinawa Prefecture. Garden eels live in the pure white sand, so let's observe them. ◇Sesoko Island has many cliff-like diving points, caves and holes, so you can see impressive scenery and fantastic curtains of light when the sunlight shines through. ◇Motobu Town is a popular swimming spot called "Gorilla Chop." It has pure white sand, and is home to several types of clownfish and colorful tropical fish. *For safety reasons, we will dive in calm diving areas from Minna Island, Sesoko Island and Motobu Town on the day. We may not be able to accommodate your request. Thank you for your understanding.

Nice to meet you. I run a marine shop in Ginowan City. This is Honu Marine. We would like to provide a friendly guide so that even those who are new to trial diving or who want to try diving but are nervous about the sea can enjoy themselves with peace of mind. We will not take you to the sea on days when the wind is extremely strong, when the sea conditions are not good, or when safety is not likely to be ensured. We hope you will participate with peace of mind. ★There are many coral reef areas around the little-known Ginowan Port Marina. ★Even in places close to land, such as in front of Tropical Beach, in front of the breakwater, and in front of Ujidomari Port, we can change the point considering the influence of waves and wind. ★Even though it is a place that can only be reached by boat without beach entry, it is close to the marina so there is no need to worry about seasickness. ★Since there are many first-time participants, we will first take you to a point where you have a high chance of encountering sea turtles in one dive so that you can enjoy it without burden. (Depending on the sea conditions) ~Experience flow~ ①Receive a lecture on the tour from the instructor. ②When you are ready to put on your wetsuit and get ready, board the boat. ③It takes less than 10 minutes to get to the point, so there's no need to worry about seasickness♪ ④When you arrive at the point, follow the instructor's instructions and head out to the sea! ⑤Enjoy the beautiful sea and fish of Okinawa. ⑥When the boat returns to the port, the tour ends. ⑦You can rent a shower at the marina for a fee.
