“Oita is famous for hot springs, but isn’t summer too hot for onsen?”
That question from our editor-in-chief Mamarin inspired us to look for
cool and refreshing places to enjoy in Oita Prefecture.
Oita is known as one of Japan’s most famous hot spring destinations,
but not every hot spring is hot.
You can also find
refreshingly cool hot springs,
including a 32°C naturally carbonated outdoor bath.
And there is much more than onsen.
From limestone caves and mountain scenery
to dolphin experiences and ropeways,
Oita has plenty of places where you can enjoy a cooler side of Japan.
Here are
five refreshing places in Oita that are also easy to enjoy for travelers in their 60s.

If swimming with dolphins has always been on your wish list,
Tsukumi Dolphin Island
is a fun place to visit.
Located in Tsukumi City,
this ocean-side attraction offers
dolphin performances,
trainer experiences,
feeding programs,
and even
“Swim with Dolphins”
experiences.
Compared with similar attractions near Tokyo,
the prices also feel relatively accessible.

If you do not want to start with a more active experience,
you can simply watch the dolphins
or try feeding them first.
Then,
depending on your energy level and comfort,
you can gradually try more interactive programs.
The dolphin feeding experience is
¥500 per cup.

One of the most memorable experiences here
is taking a boat ride while dolphins swim right beside you.
It feels very different from watching them from a platform.
You can see them racing through the water up close
as they splash beside the boat.
The boat experience is
¥2,000 per boat
and includes dolphin food.
Being able to enjoy such a close dolphin experience for this price
makes it especially appealing.
There are also penguins,
fish,
and other marine animals.
It can be enjoyable for travelers in their 60s and 70s,
and also works well for a multigenerational family trip.
