It's incredibly cost-effective, and we love spending about a week there,

01. A Tsushima Snorkeling Gem Perfect for Kids
Katsumi Beach is conveniently located
about halfway between Hitakatsu and Izuhara.

When we first visited, we only planned a quick stop,
but the incredible underwater clarity kept us there
much longer than anticipated!
After that, we started coming prepared with all our gear,
and it became our go-to spot for half-day snorkeling adventures.
The very first thing that grabbed our attention upon arrival was
the incredibly transparent water.

My daughters exclaimed the moment they stepped out of the car,
"Mom, the water is really clear!"
That's how clear it is! Unless there are high waves,
the water truly has a fantastic color.

This is exactly why it's become one of the most popular spots
for anyone seeking incredible snorkeling in Tsushima.
Even right by the shore,
the water was so clear you could see straight to the bottom,
and spotting fish was a breeze.

02. Water Color and Depth at Katsumi Beach
When I actually went in,
the sections close to the beach are shallow,
perfect for kids to splash around.

It's also great for playing on inflatable tubes or building sandcastles,
so parents can relax and enjoy themselves.
The sand quality is excellent too, making it very suitable
for kids to play in the sand.

While the water depth gradually increases,
there are also sections where it suddenly gets deep
if you venture further out.
In fact, while I was snorkeling,
I suddenly encountered a deep section,
and around it, I saw many large fish
that you'd typically find in a raw fish restaurant's aquarium!
So, if you're visiting with young children,
I highly recommend wearing
life jackets.

03. The Underwater Scenery and Fish I Actually Saw
The reason I love summer trips to Tsushima
is precisely because the environment is perfectly suited
for snorkeling.

When you put on a mask and peer into the water,
you can easily spot schools of small fish
swimming all over the place.
Even close to the beach,
fish were easily visible.
As I ventured a bit deeper,
larger fish started appearing too, giving me the feeling
I was inside a sushi restaurant's aquarium! Haha.

It might not have the vibrant corals
of Southeast Asian seas, but with plenty of fish,
it was still a thoroughly enjoyable ocean
for families to have fun.

Also, just for fun, I bought a bamboo fishing rod
from a 1000-yen shop and tried fishing.
The bites were quicker than expected,
so even adults had a great time.
Although mostly small pufferfish were caught,
we observed them and then released them back into the sea,
creating wonderful memories.

04. Snorkeling Essentials and Precautions
If you're planning to go snorkeling in Tsushima,
there are some essential items you absolutely must bring.
✔ Snorkeling Mask
✔ Aqua Shoes
✔ Life Jacket
✔ Sunscreen
✔ Hat
✔ Water and Snacks
✔ Shade Tent or Mini Tarp
You might think, "Can't I just buy them there?"
but absolutely not.
There aren't many places selling water play gear.
I strongly recommend purchasing them in your home country
before you go.

Especially, make sure to bring aqua shoes.
If you look into the water,
you might find areas with sea urchins or shellfish.
I recommend wearing sneaker-style aqua shoes
with thick soles, rather than sock-style ones.

05. Review of Katsumi Beach Showers and Facilities
One of the most satisfying parts after finishing our water activities
was the shower facility.
There's a free shower facility available,
making it easy to quickly rinse off and head out.
While the facilities aren't brand new and show some age,
they were kept clean and well-maintained.

However, I usually just towel off quickly
and head to the nearby hot springs.
And while there is a spot to escape the sun,
it's quite small.
That's why whenever I visit this spot,
I make sure to bring a mini tarp with me.

Some folks bring shade-only tents,
while others opt for parasols,
so feel free to bring whatever you find most comfortable!

06. The Perfect Itinerary: Beach Fun, Shopping, and Hot Springs!
To be honest, the main reason I absolutely love Katsumi Beach
goes beyond just the sand and sea.
It's all about the amazing infrastructure surrounding it.
You'll find Tsushima's only Daiso, a Value Mart,
and even a pizza place all within easy reach.
We usually start by grabbing snacks and drinks at Value Mart
before heading to the beach for some exciting fun.
And after all that splashing around,
we make our way to Yuttari Land to freshen up, then it's 'go-go' back to our accommodation!
I can't recommend this itinerary enough!
Kids get to revel in their water adventures,
adults can melt away their fatigue in the rejuvenating hot springs,
and everyone gets to enjoy some shopping,
so it's a guaranteed win for the whole family, don't you think?

07. Why Tsushima is the Perfect July Family Getaway
If you're eyeing Tsushima as your next July getaway,
you'll want to thoroughly research your trip
and pack all your essentials
to ensure you make the most of every moment, right?
Enjoy water fun safely in its shallow waters,
snorkel among a vibrant array of fish,
and then indulge in some shopping and a relaxing onsen experience.
If a family adventure to Tsushima is on your radar,
make sure to save this spot and pay it a visit!

Especially for those seeking a top snorkeling spot in Tsushima,
or a perfect place for water play with kids,
it will be a choice you won't regret.
We're actually planning to visit Tsushima again this July as our overseas travel destination,
and Katsumi Beach is definitely on our itinerary!
Stocked up with plenty of delicious treats, of course! ^^

01. Tsushima Snorkeling Spot Perfect for Families with Kids
Katsumi Beach
is located about halfway
between Hitakatsu and Izuhara.

Initially, we thought we'd just stop by for a moment,
but the underwater conditions were so good
that we ended up staying much longer.
After that, we prepared everything needed
and it became a spot where we'd spend half the day enjoying snorkeling.
The very first thing that caught our eye upon arrival was
the incredibly clear seawater.

As soon as our daughters got out of the car,
they exclaimed, "Mom, the water is so clear!"
That's how good the water color is,
as long as it's not a day with high waves.

That's why it's also the most visited spot
for those looking for snorkeling points in Tsushima.
Even close to the shore,
the water was clear enough to see right through,
and fish were easily spotted.

02. Water Clarity and Depth at Katsumi Beach
When I went in myself,
I found that the area close to the beach was shallow,
perfect for children to play in the water.

It's also great for playing with tubes or building sandcastles,
allowing parents to relax and enjoy without worry.
The sand condition is excellent, making it very suitable
for children to play in the sand.

Although the depth gradually increases,
there are also sections where it suddenly gets deep
as you move further out.
So, while snorkeling,
I suddenly encountered a deep section,
and around it, I saw many large fish,
like those you'd see in a sushi restaurant's fish tank.
Therefore, if you're visiting with young children,
I highly recommend that they wear a life vest.

03. The Actual Underwater Scenery and Fish
The reason I love summer trips to Tsushima
is precisely because the environment is perfectly suited
for snorkeling.

When you put on a mask and look underwater,
you can easily spot schools of small fish
swimming around everywhere.
Even close to the shore,
fish were easily visible.
As I ventured a little deeper,
larger fish started to appear,
and it felt like being inside a sushi restaurant's aquarium. Haha!

Unlike the seas of Southeast Asia,
there aren't vibrant corals,
but with plenty of fish, it was a sufficiently fun ocean
for families to enjoy.

Also, just for fun, we bought a bamboo fishing rod from a 1000-yen shop (around ~$6)
and tried fishing. The bites were quicker than expected,
making it enjoyable for adults too.
Although mostly small pufferfish were caught,
after observing them, we returned them to the sea,
and made some wonderful memories.

04. Snorkeling Essentials and Precautions
If you're planning to go snorkeling in Tsushima,
there are some essentials you absolutely must pack.
✔ Snorkeling mask
✔ Aqua shoes
✔ Life vest
✔ Sunscreen
✔ Hat
✔ Water and snacks
✔ Shade tent or mini tarp
You might be thinking, "Can't I just buy them there?"
But I strongly advise against it!
There aren't many places that sell water activity gear.
I really recommend buying them before you go
and taking them with you.

Especially make sure to bring aqua shoes.
If you look closely in the water,
you'll find areas with sea urchins or shellfish.
Instead of sock-style ones, I really recommend wearing sneaker-style aqua shoes
with a thick sole.

05. Katsumi Beach Shower Facilities and Amenities Review
After finishing our water activities, one of the most satisfying aspects
was the shower facility.
There are free shower facilities available,
making it great for a quick rinse before heading off.
The facilities aren't brand new and show some age,
but they were kept very clean.

However, I usually just towel off roughly
and head to the nearby hot springs instead.
There's also a small shaded area,
but it's quite cramped.
That's why when I visit this spot,
I always bring a mini tarp to use.

Some people bring shade tents,
while others bring parasols,
so just use whatever is most comfortable for you.

06. The Best Itinerary: Combining Shopping and Hot Springs
Actually, there's a big reason why I love Katsumi Beach so much.
It's all about the surrounding infrastructure.
Tsushima's only Daiso, as well as Value Mart
and a pizza place, are all nearby.
We first bought snacks and drinks at Value Mart,
then had a blast at the beach.
After our water activities, we headed to Yuttari-land
to freshen up before going back to our accommodation!
I truly recommend this itinerary.
The kids get to enjoy playing in the water,
the adults can relax and unwind in the hot springs,
and you can even squeeze in some shopping!
It's a win-win for the whole family, with high satisfaction all around, wouldn't you agree?
