Last year, I visited Shakotan for the first time and fell in love at first sight with the stunning Shakotan Blue.

This year, I decided to try something different and challenge myself with night snorkeling!

The day before, there was heavy rain in Hokkaido, so I was worried about whether we could actually snorkel with water overflowing from various places. However, when I called to confirm, I received the reassuring words, "Of course you can! We did it even during the day when it was raining!" So, …
Last year, I visited Shakotan for the first time and fell in love at first sight with the stunning Shakotan Blue.

This year, I decided to try something different and challenge myself with night snorkeling!

The day before, there was heavy rain in Hokkaido, so I was worried about whether we could actually snorkel with water overflowing from various places. However, when I called to confirm, I received the reassuring words, "Of course you can! We did it even during the day when it was raining!" So, off I went for my first snorkeling and night snorkeling adventure!

Since it was my first time, the explanations were clear and thorough. After putting on the wetsuit and life jacket, we walked about five minutes to the beach and entered the water! The beach was very calm, with no waves at all!

I was really anxious because I can't swim (even though I was the one who wanted to do night snorkeling, haha), but I held onto a kickboard and was pulled by the instructor. It was super easy! When I thought about it, I had fins and a life jacket on, so I could swim after all!

When I looked into the water, I was surprised to see so many different fish! On the sea urchin road, there were tons of sea urchins! As expected of Shakotan!

I also got to hear many funny stories from the instructor, and they even dove down to collect starfish and sea urchins for me to touch!

While doing all this, we arrived at a cave!

With my heart racing, I turned off my flashlight inside the cave, and when I peered into the pitch-black sea, I saw shimmering bioluminescent plankton... I couldn't help but exclaim, "Wow!" while waving my hands around. The bioluminescent plankton react to stimuli, so as I looked while being pulled along, I saw them scatter, responding to the instructor's fins, like countless shooting stars flowing by.

I learned that bioluminescent plankton can be seen anywhere in Japan, but because there are fewer plankton remains in the sea around Hokkaido, they can be seen more beautifully here than in any other sea in Japan.

Thank you for such a fun time! The night sea was magical, and I had a precious experience that left me very satisfied. I think I might get hooked on snorkeling!

I want to come back next year—Shakotan! And night snorkeling! Next time, I want to swim on my own!
去年、初めて積丹へ来て、見事なまでの積丹ブルーに一目惚れしました(人*´∀`)

今年は趣向を変えてナイトシュノーケルに挑戦っ‼︎

前日に北海道で大雨ということもあり、当日は滝のようにいろんな所から水が溢れており、シュノーケルできるのか不安でしたが、

当日、確認のためにした電話では「もちろんできますよ‼︎日中も雨でもやってました‼︎」との心強いお言葉をいただき、いざ、初めてのシュノーケル&ナイトシュノーケルへ‼︎笑

初めてということでわかりやすく、丁寧な説明をしていただき、ウェットスーツやライフジャケット等を装備ののち…

今年は趣向を変えてナイトシュノーケルに挑戦っ‼︎

前日に北海道で大雨ということもあり、当日は滝のようにいろんな所から水が溢れており、シュノーケルできるのか不安でしたが、

当日、確認のためにした電話では「もちろんできますよ‼︎日中も雨でもやってました‼︎」との心強いお言葉をいただき、いざ、初めてのシュノーケル&ナイトシュノーケルへ‼︎笑

初めてということでわかりやすく、丁寧な説明をしていただき、ウェットスーツやライフジャケット等を装備ののち、5分くらい歩いた海岸から着水っ‼︎
とても穏やかな海岸のようで波は全くなかったです‼︎

泳げないため、不安で不安で仕方なかったのですが、(自分からナイトシュノーケルやりたいといったくせに笑)ビート板に捕まってインストラクターの方に引っ張ってもらいました♪
すっごく楽チンでした♪笑
よく考えたら足ヒレ付けてライフジャケット着るので泳げました笑

海の中を覗くといろんな魚がたくさんいてびっくり‼︎
うにロードでは大量のうにがいました‼︎さすが積丹‼︎‼︎

インストラクターの方のおもしろい話もいっぱい聞けて、笑
ヒトデやウニを潜って採ってきてくれて触らせてもらって‼︎‼︎ヽ(゚∀゚)ノ

そんなこんなをしているうちに洞窟に到着‼︎

洞窟の中でドキドキしながら懐中電灯を消し、
真っ暗な海の中を覗くと、キラキラと揺らめく夜光虫が。。。。。
シュノーケルを付けたまま
わぁぁぁo(*>▽<*)o
と歓声をあげてひたすら手を動かしてました☆★
夜光虫は刺激に反応して光るとのことで、引っ張ってもらいながら覗くと、インストラクターさんの足ヒレに反応して光りながら散っていくんです☆★☆★☆
まるで無数の流れ星が流れているようでした(人´∀`*).。:*+゜゜+*:.。.*:+☆

夜光虫は日本中どこでも見れるとのことですが、北海道の海ではプランクトンの死骸が少ないため、日本中のどこの海よりも綺麗に見ることができるそうです☆★

とても楽しい時間をありがとうございました‼︎
夜の海は幻想的で、貴重な体験をさせてもらい、大満足でした♪♪
シュノーケルにハマってしまいそうです♪

また来年も来たいな〜♡積丹♡
そして、ナイトシュノーケル♡
今度は自力で泳ぎたいと思います笑

I participated in bioluminescent snorkeling! It was my first time snorkeling, but they carefully and thoroughly taught me how to put on the wetsuit, use fins, and wear the underwater goggles, so I was able to enjoy it without any worries! The weather was clear that day, and the starry sky was amazing! The bioluminescent organisms were also very magical!

It seems that the meeting time for night snorkeling changes according to sunset, so be sure to check for updates from the shop! When putting on the wetsuit, participants go outside together, so it's best to bring your swimsuit. It was smoother to wear it before going to the shop.
夜光虫のシュノーケリングに参加しました!
初めてのシュノーケリングでしたが、
ウェットスーツの着方から足ヒレ、水中ゴーグルの使用方法まで細かく丁寧に教えてくれて、不安なく楽しめました!
当日は快晴で満点の星空が素晴らしかったです!
夜光虫もとても幻想的でした!

夜のシュノーケリングは日の入り時間に合わせて集合時間が変わるようなのでお店さんからの連絡、要チェックです!
