Escape the summer crowds and discover Tsushima Island's best-kept secret water spots. From serene beaches to hidden coves, find your perfect peaceful getaway for 2026.
Have you planned your summer vacation yet?
As you search for an international travel destination for July,
are you feeling the pinch of costly flights,
finding popular resorts packed with people,
and hesitating due to high airfares?
If so, how about taking a ferry from Busan,
and arriving at Tsushima in just 1-2 hours?
Tsushima Island is part of Japan's Nagasaki Prefecture,
an enchanting destination featuring emerald-hued seas
and peaceful, secluded beaches.

One of its greatest perks is enjoying the ocean at a relaxed pace, without the bustling crowds of more famous tourist destinations.
This truly is its biggest advantage.
While most travelers
only stop by Miuda Beach and head back,
Tsushima actually boasts
a wealth of hidden gems perfect for water activities!
This summer, I'll introduce you to 7 Tsushima water spots
where you can enjoy a peaceful and refreshing escape.
You won't find this kind of exclusive information
anywhere else, believe me!
Get ready for your 1-night, 2-day Tsushima adventure,
because I'm about to unveil some incredible, hard-to-find tips!

1. Miuda Beach
This is Tsushima's iconic beach.
Boasting breathtaking scenery, it was even chosen as one of Japan's Top 100 Most Beautiful Beaches, captivating visitors with its emerald waters and pristine white sands.

It's conveniently located just about 5 minutes
by car from Hitakatsu Port, making access a breeze.
If this is your first time visiting Tsushima,
you could say it's an absolute must-see,
a crucial first stop on your adventure.
On a particularly clear day,
you'll be treated to scenery as breathtaking as any Southeast Asian resort,
and
you can even observe tropical fish beneath the waves.

If your ideal getaway involves just the beach and a comfortable hotel stay,
you can book Toyoko Inn Hitakatsu
and easily walk to the beach.

The hotel is also conveniently located within walking distance
of Nagisanoyu Onsen,
so after a refreshing swim and drying off,
I highly recommend indulging in the hot springs.

2. Mogi Beach
This is a hidden gem located in Hitakatsu.
Most tourists
tend to pass it by unknowingly,
which means you can enjoy a beautifully tranquil
atmosphere here.
The beach is well-equipped with shade covers,
and during the peak season, the showers and changing rooms
are meticulously maintained by on-site staff,
ensuring they are always spotless.
For anyone seeking a peaceful summer escape
in Hitakatsu, this spot comes highly recommended.
With its long stretch of sand
and a gentle slope where the water gradually deepens,
it's absolutely perfect for young children to play safely.
3. Mitsushima Beach (Katsumi Beach)
This beautiful beach is one you'll encounter as you travel
from Hitakatsu towards Izuhara.

Situated on the eastern side of Tsushima,
it's a bit further south from the island's center, heading towards Izuhara.
Also known as Katsumi Beach,
it's a favorite among families, thanks to the adjacent Green Park.
Offering both a vast grassy lawn and exciting water activities,
it's an ideal spot to visit
with children.

You can even spot tropical fish in the shallow waters,
and try your hand at fishing from the rock formations.


After your water fun, nearby
Yuttari Land Hot Spring is a place my family absolutely loves, thanks to its fantastic location!
However, the shower facilities and restrooms are a bit older compared to other places.
But they are spotlessly maintained, so as long as we use them thoughtfully, everyone can enjoy them cleanly.
4. Oura Beach
It's a tranquil beach located south of Izuhara.
You can enjoy both camping and water activities simultaneously, as it's accessible with the Aoshionosato Natural Park Campground.
In fact, it was our family's secret hideaway when we chose Tsushima as our overseas travel destination last July!

Its crystal-clear waters and peaceful atmosphere are incredibly charming, and it's the only campground on Tsushima where you can enjoy a BBQ even if you're not staying overnight.

Even if you're not camping, you can still rent cabins and bungalows at affordable rates.
As it's a pebble beach with deep enough waters, those who enjoy free diving or snorkeling can indulge without even needing a boat ride out.


5. Ayumodoshi Natural Park
While not a beach, it's an absolute must-visit summer escape on Tsushima!
Valleys carved by millennia of flowing water and intriguing rock formations create a stunning landscape.


Thanks to the cool valley water and lush forest,

you can comfortably enjoy water activities
even in the peak of summer.

Grab a tube and it transforms into your very own natural water park!
There are also deep pools, offering a variety of ways to have fun.
It's a place where you can discover yet another charm of Tsushima.

6. Tsutsui-tangata Beach
This is a hidden gem of a beach located at the southernmost tip of Tsushima.
It boasts an impressive long white sand beach and expansive sea, a place where you'll find neither tourists nor many locals.

The scarcity of crowds allows for a truly tranquil resort atmosphere,
yet its facilities were surprisingly the cleanest and best!

It's also a wonderful spot for a leisurely stroll while gazing out at the sea.

Just a heads-up, it is quite a distance, being at the very southern end.
7. Kodomohama Beach Park
This is a hidden gem for healing and relaxation in Tsushima's southern region.
It features a pristine beach and well-maintained walking paths,
a perfect place where you can leisurely unwind while admiring the ocean views.

Not widely known among tourists,
it's perfect for enjoying the sea in a tranquil atmosphere.
This place is renowned for its breathtaking sunsets!
