I was disappointed that the disability discount was not applied. The underwater observation boat "Submarine Jr. II" was not as impressive as I had hoped, and I felt the price was a bit high.障害者割引が適用されなくて残念でした。海中展望船「サブマリンJr.Ⅱ」も期待したほどではなく、値段も割高に感じました。

There were fewer fish than I expected, and I couldn't hear the explanation very well.

This was my second time participating, but there were fewer fish than I expected, and I couldn't hear the guide's explanations very well. I could see the fish well from one side of the window, but I couldn't see any fish from the other side at all. Since I was holding my child in a baby carrier, it was difficult for me to change my position, which was disappointing.二回目の参加でしたが、思っていたより魚が少なく、添乗員の説明もよく聞こえませんでした。片側の窓だけ魚がよく見え、対側の窓は全く魚が見えませんでした。抱っこ紐で子供を抱えていたため、自分の向きを変えることがむずかしく、残念でした。

The sea wasn't too rough, but I couldn't see many fish during the cruise in the bay. It felt like it ended with a discussion about farmed coral.海はそんなに荒れてはいないのに湾内でのクルーズで魚をあまり観る事が出来なかった。養殖珊瑚の話しで終わった感じでした。

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.

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, 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.

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。

当日は朝から雨。ホテルに電話をこちらから入れました。当日催行するのかと確認したところ、出航の1時間前に決定するとのこと。
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。

The sea was rough, and unfortunately, we could only visit one of the two points. It was quite shaky, which made the kids feel sick, so that was disappointing. However, it was nice to see the beautiful coral farming underwater and to spot sea turtles.海が荒れていて
二つのポイントのうち一つのみとなってしまったこととやはりかなり揺れていたので子供達も気持ち悪くなってしまい残念でした。

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。

A trip to Okinawa with three generations. I made the reservation so that the children could enjoy it. The result was... great! The kids had more fun than I expected, happily exclaiming, "Look at the fish!" and "Over there and over here!" It might be a good choice for families with children!3世代で沖縄旅行へ

I signed up for this tour because I wanted to see the natural fish of Okinawa. Although the time flew by and I wished I could have stayed on the boat a little longer, I was satisfied to see various types of coral and fish that are different from those in an aquarium. The staff mentioned that there are times when you can see turtles as well, so I look forward to that on my next visit.沖縄の自然な魚達が見たくてこちらのツアーを申し込みました。
時間的にはあっという間でもう少し船に乗っていたいという気持ちでいっぱいですが、水族館とはまた違ったサンゴや自然の色々な種類の魚が見れて満足出来ました。
また、亀が見れる時もあるとスタッフの方がおっしゃっていたので、次に来た時に期待したいと思います。

I saw two sea turtles. I enjoyed it because it was my first time seeing the transparent coral reef on the ocean floor. It was a day with high waves and strong swells, so my elementary school-aged child got seasick and was exhausted by the end, but they were still satisfied that it was worth participating since we got to see the sea turtles.ウミガメを二匹見ました。透き通った海底のサンゴ畑を初めて見たので興味深く楽しめました。波が高く揺れが激しい日だったので小学生の子供は後半酔ってしまいぐったりでしたが、それでもウミガメが見れたことで参加した甲斐があったと満足してました。

A big family trip with three families, including children and grandchildren. The ages of the grandchildren range from 1 to 10 years old, which made it challenging to plan activities that would interest everyone. However, everyone was thrilled to encounter the coral, fish, and sea turtles underwater. It was a very satisfying experience.子供や孫達と3家族の大家族旅行。

The water was clearer than I expected, and I was able to see various marine life. I even encountered sea turtles twice. It's recommended because you can look into the ocean without getting wet.思ったよりも透明度が高く、様々な生物を見ることができました。

The staff were very kind and happily took family photos for us, creating wonderful memories of our trip!

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。
