I was a bit worried because there were price differences on the site and there were no reviews, but there were no concerns at all, and I had a great time. The staff were also very friendly.サイト内に値段の差があり一番安かった事や口コミがなく少し心配でしたが、不安要素など何もなく十分楽しめました。スタッフの方も親切でした。

I had a great time seeing various corals and fish in different places! I was surprised to see a sea turtle at an unexpected moment too. The sea was very clear.サンゴ、お魚が色々や場所で見れて楽しかった!!予想していなかったタイミングでウミガメもー。とっても透き通った海でした。

Too much packed into one.

They may be adhering to the passenger limit, but with about 50 people on board, it feels like a Tokyo morning commuter train where your shoulders touch the person next to you. It can be uncomfortable and makes it hard to focus on the glass boat experience.

To provide a good experience, I believe it's more important to consider how many people can enjoy the glass boat experience rather than just sticking to the passenger limit.
乗船できる人数は守っているのかもしれないが、一隻に50人程乗っており、隣の人と肩が触れ合う東京の朝の通勤列車のよう。不快な気分にもなるし、グラスボートに集中できる状態にならない。
良い体験を与えるためは乗船人数制限を守ることよりも、どの程度であればグラスボートを堪能できる体験を提供できるかというお客様目線が必要だと思う。

It was fun. I wanted to watch longer.

There are multiple companies operating, and I unknowingly waited in the waiting area of a different company. When it was time to board, I was told I needed a ticket, which surprised me because I thought I could just show my smartphone screen.
The sea was beautiful, and I could have stared at it forever.
運営する会社が複数あって、知らずに違う会社の待合所で待ち、いざ乗るときにチケットないとダメと言われました。スマホ画面見せればいいのかと思ってたので慌てました。
海はきれいでずっと眺めてたいくらいでした。

I made a reservation through Veltra and participated on a sunny morning in May. It had been a while since I last took a glass-bottom boat, and the scenery in Kabira Bay was beautiful. The points of interest were close by, and I was able to see manta rays and sea turtles. Although the tour lasted 30 minutes, I felt very satisfied. Additionally, since boats depart every 15 minutes, it was convenient to go at a time that suited me. I highly recommend this tour in Kabira Bay, Ishigaki Island.

久しぶりのグラスボートでしたが、川平湾内もきれいで、ポイントも近く、マンタやウミガメも見れました。
ツアー時間30分ですが、大満足できると思います。
また15分おきに船が出ているのである程度好きな時間に行けるのも楽で良かったです。
石垣島川平湾のおすすめツアーです。またの機会に参加したいです。

I was lucky to see sea turtles!

At first, I was worried about how many fish I would see, but when we arrived at the spot, it was a fish paradise! We also hit the jackpot with sea turtles and saw many of them! However, despite the calm winds, there was quite a bit of rocking, so those who are prone to motion sickness might need to be cautious. But my 4 and 7-year-old kids were totally fine with the rocking and were engrossed in looking underwater.初めはどれくらい魚見えるのかなぁ?と不安でしたが、ポイントに着いたらお魚パラダイスでした!海カメのスポットもドンピシャで、沢山見れました!ただ風が少ない日にも関わらず揺れはけっこーあったので、酔いやすい人は注意が必要かもしれませんが、うちの4歳7歳のこどもたちは揺れにもへっちゃらで夢中で海中を覗いていました。

I used the service on the afternoon of July 16. This year, the rainy season was long, so they took us a bit further out because the visibility in Kabira Bay was poor. They mentioned that if we were lucky, we might encounter turtles, and they really made an effort to find spots where turtles might be. We actually encountered one! They also provided various explanations about the fish and corals, and I had a great time.7月16日の午後に利用しました。今年は梅雨が長かった為川平湾内の透明度が悪いと言う事で少し沖の方へ行ってくれました。運が良ければ亀にも遭遇出来ますよと言って一生懸命亀のいそうな場所を探してくれて本当に遭遇出来ました。魚の名前や珊瑚の事など説明も色々してもらい、良い時間が過ごせました。

The temperature was 22 degrees, so it was just barely possible to swim, which is why I booked this glass-bottom boat.

The boat was private, and they provided detailed explanations of the points where we could see fish, plus I enjoyed chatting with the staff.

普段はシュノーケリング派なのでグラスボートは久しぶりです。
船は貸切で、魚が見れるポイントを詳しく説明してくれるし、スタッフと世間話みたいな感じもできるし楽しかったです。
12月は透明度が高く魚がよく見えました。亀は波の関係でポイントには行けませんでしたが、テンション上がるグラスボートでした。

It wasn't as blue as I thought.

I thought I would see more coral, but it wasn't that much. It was better to look at the surface of the sea from the boat than to see the seabed through the glass.もっとサンゴとか見れるかとおもったがそれ程でなかった。
ガラス越しに海底を見るより、船から海面を見ている方が良かった。

It was so much fun that it felt like a moment.

It was very enjoyable.
I think luck played a part, but this time I was able to see three sea turtles and got quite excited ( ̄∇ ̄).

It's a selfish wish, but I thought it would be nice if there were plans for a longer duration (^^).

If you have flexibility in your schedule or time, it might be better to aim for just before or after high tide (^o^).
とても楽しいです。
運もあるとは思いますが、
今回はウミガメも3匹も見れて
大人気なく結構興奮してしまいました( ̄∇ ̄)

勝手な希望ですが、
もう少し長い時間のプランがあったら
いいなと思いました(^^)


日程や時間に余裕がある場合は、
満潮前後を狙ったほうがいいかもです(^o^)
