I realized that there are a lot of fish in the waters of Okinawa. It was great to see them easily without having to dive. The cruising after getting back up to the deck was unexpectedly pleasant. It was the only sunny day of my three-day trip, so I felt lucky.沖縄の海中に大量の魚がいることを実感。
ダイビングをしなくても、手軽に見れて良かった。
帰りのデッキに上がってからのクルージングが予想外に気持ち良かった。
3日の旅行の唯一の晴れだったので、ラッキーだった。

On the day of the trip, it rained from the morning. I called the hotel to confirm whether the tour would proceed, and they said a decision would be made one hour before departure.

結果、小雨で催行されましたが、透明度も低く、あまり良く見えませんでした。
スタッフさんは、しっかりと魚の説明等をしてくれましたが、イマイチな海の中。
少ない日程での旅行なので、もう少し早めの決断をしてくれると予定の変更など出来、ありがたいなぁと思いました。

I have ridden a glass-bottom boat in Miyako Island before. The water clarity is about the same for both. The variety and beauty of the corals are better here. Although the price is higher here, I felt that the experience time was short at just 30 minutes. I was able to see sea turtles in Miyako Island, but I couldn't see any here. Perhaps it's because of the corals; I think they can't scatter food to attract fish here, but in Miyako Island, I was able to see the fish at a very close distance.今までに宮古島のグラスボートには乗ったことがありました。
海の透明度はどちらも同じくらいです。
サンゴの種類と綺麗さはこちらの方が上です。
価格はこちらの方が高いのに、体験時間が30分で短いと感じました。
宮古島ではウミガメが見れましたが、こちらでは見れませんでした。
恐らくサンゴのため、餌を撒いて魚を集めることができないのだと思いますが、宮古島ではかなり近い距離で魚を見ることができました。

ちえ

Even though it was hot, it was comfortable and we didn't get wet, making it a good tour for families with children! However, there were unavoidable situations, such as not seeing any fish on one side, and the tour was quite short, around 15 minutes, so I can't deny that it felt a bit lacking.暑くても快適ですし、濡れなくて済むので子連れには良いツアーでした！
ただ片側は全く魚が見れないなど、致し方ない状況はあるのと、15分くらいの短いツアーなので物足りなさは否めませんでした。

Since it was the rainy season, I was prepared for rain, but fortunately, we were blessed with great weather and were able to see a beautiful emerald green sea. The staff were all kind, and I was moved by the colorful schools of tropical fish. Above all, I was deeply touched to see the coral that the fishermen had planted, hoping to restore the beautiful sea of the past. My mother, who visited Okinawa for the first time, was also very happy and said, "It was such a beautiful sea!"

Thank you very much. 通年であれば梅雨の時期だったので雨天も覚悟していたのですが…幸い天候に恵まれて、とても綺麗なエメラルドグリーンの海が見られました。
スタッフさんは皆親切でしたし、熱帯のカラフルな魚の群れに感動しました。何より、途中で漁師さんたちが「昔の綺麗な海を取り戻したい」と植えたという珊瑚なども見ることができ、とても心に残りました。
初めて沖縄を訪れた母も「綺麗な海だったー！」と大変喜んでおり、参加した本当に良かったと思います。ありがとうございました。

I went at the end of March on a cloudy day when it was raining continuously. I was worried that the sea might be murky and hard to see, but I was able to enjoy watching the corals, fish, turtles, and squid swimming gracefully, which was a lot of fun! The glass was on the side, and since I had taken motion sickness medication in advance, I didn't get seasick at all. I'm glad I went! Thank you very much.3月末、雨が続いていた曇りの日に行きました。
海が濁ってよく見えないのではないかと心配していましたが、珊瑚や魚、亀やイカなど、悠々と泳ぐ姿を見ることができて、とても楽しかったです！

I went on the Submarine Jr. II glass-bottom boat experience. The meeting place is in front of the information center near the chapel at the ANA InterContinental Manza Beach Resort. The experience lasted about 30 minutes. The windows of the boat were large, allowing us to see small fish, sea turtles, and even some larger sea turtles and coral. Inside the boat, there was a friendly explanation from the staff, and there were also quizzes, which made it very enjoyable.

Towards the end of the experience, we went out onto the deck to enjoy the beautiful scenery outside, and the staff member who explained everything also took photos for us. If you ever go to Okinawa, I highly recommend trying this experience! サブマリンJr.Ⅱグラスボート体験に行って来ました。

なな

Wearing a diving suit and diving into the ocean is challenging, but I signed up because I wanted to do something that feels like Okinawa. Since it was a weekday, we had the place to ourselves, and while learning about the fish and coral, I was able to experience underwater scenery that I usually wouldn't see, which was fantastic. It felt like it went by in an instant. I will definitely use this service again.ダイビングスーツを着て海に潜るのは大変だけど、沖縄っぽいことがしたいということで申し込みました。平日だったので貸切状態で、海の魚やサンゴについて説明をしてもらいながら、普段は見ることのない水深の景色まで体験できてとてもよかったです。あっという間に感じました。また利用させていただきます。

I stayed at this hotel during New Year's, and there were people swimming, but it wasn't the season for swimming in the pool or the ocean. However, it was a fun experience to be out on the water. The sea was rough, so we could only go to the inland spots, but I was very satisfied to see tropical fish and sea turtles.お正月にこのホテルに宿泊し、泳いでる人たちもいましたが、季節的にもプールや海では泳げませんでしたが海の上に出れて楽しい体験でした。

The waves were high, and the pier was swaying significantly during the activity. Inside the submarine, the staff occasionally made announcements, but their voices were drowned out by the surrounding noise, making it impossible to hear what they were saying. At one point, they mentioned that due to the high waves, we couldn't go out to sea, so we ended up seeing a few small, murky fish that weren't even particularly pretty, and it was over quickly. It was a struggle just to find any regular fish,… The waves were high, and the pier was swaying significantly during the activity.

It was a struggle just to find any regular fish, let alone turtles.

It felt like a conveyor-belt option. If they knew beforehand that we couldn't go out to sea due to the high waves, shouldn't they have asked participants whether they wanted to proceed before boarding?

In any case, it was an option that did not match the price. I do not recommend it at all. 波が高く桟橋が大きく揺れる中の催行でした。

A big family trip with three families, including children and grandchildren.
