First, everyone gathered to board the boat and set off for Kashiki Island. The snorkeling instructor was Chinese, and there were also Mandarin-speaking people on the island who were very friendly and helpful! They even helped take beautiful photos 😻 In the afternoon, you can continue swimming or sunbathing in the Aharen Sea. Many shops there speak Chinese and you can rent parasols and lounge chairs! The curry rice served at the shops was incredibly dry and delicious! 🍛❤️ Overall, it was a fantastic experience! Worth every penny! Highly recommended! On a side note, the high-speed boat was super fast and exhilarating! But I suggest taking seasickness medication so you can sleep right after the ride, haha, even if it's going fast, you can still sleep 😘🫶🏻
In March, I was busy with work and, feeling down, booked a one-day diving experience at the Kerama Seas on KKDay. The yen was high then, thankfully I had a discount coupon... It's only now that I'm reviewing this June diving experience! It was a Sunday, and there were many people participating, including tourists from various countries and several instructors speaking Chinese, English, and Japanese. The advantage was that I didn't have to worry about language barriers. The disadvantages were that the underwater time was short, and there was a queue to shower and change at the end. There were three dive sites, and each dive with a tank lasted about 15 minutes (it seems you can buy extra dives). The rest of the time was free for snorkeling (you can wear a life jacket while snorkeling, so it's okay if you can't swim). The instructor, Summer, was a Taiwanese woman. She explained things very thoroughly and was very attentive to our needs. Knowing I'm not a very good swimmer, she held my hand the whole time to help control the direction and even helped us take photos with sea turtles (although the turtles kept swimming, so the photos weren't very clear XD). The lunchbox was quite delicious (maybe I was starving from the water activities XD), the weather was fantastic, and the Kerama Mori Islands were absolutely gorgeous!! We finished earlier than planned, but I think it was totally worth it, and the free shuttle bus was very convenient~
