Are there any good snorkeling sites around Kyushu in southern Japan? Is it warm enough to do this in April? (Context: newbie snorkelers... one or two days. Preferably not an island outside of Kyushu.)
I'm assuming you're talking about The Kyushu region (including okinawa and the islands)
I recently returned from ishigaki (an island in the Kyushu region). We did snorkelling and scuba out there.
Most dive schools will not take Non Japanese newbies. As we don't speak japanese we found an excellent english speaking dive school. If you're looking to go Snorkelling through a dive school i'd reccomend Dive school Umicoza. A Day's Snorkelling will cost 8,400 yen. This includes:
I went in september and they had 2 english speaking guides (one also spoke chinese, and french). We did Scuba and snorkelling with them and the marine life was spectacular on both. The guides were awesome and it was just an amazing day. Their website is here
If you'd just like to go to the dive site without going through a dive school (i really don't recommend this) then here's a link to it on google maps.
The sea temperature will be fine in april as ishigaki's sea temperature ranges from 21°C in winter to 29°C in summer
Let me know if you have any more questions.
