If you’ve spent a summer in Japan, you’ll know how brutally hot it can get.

One summer activity we’ve really fallen in love with as a family is 川遊び (kawa-asobi) — literally, river play.

Think icy-cold mountain water, kids splashing around, BBQ, camping chairs, tents, picnic mats and spending almost an entire day outside with friends and family.

This is our third summer doing 川遊び since moving back to Japan with our son, and we definitely did not start out this prepared. 😂

Our first 川遊び was literally just a picnic mat

The first year, some friends invited us for our first river day.

We turned up with basically a picnic mat.

No proper camping setup.
No outdoor wagon.
No camping chairs or table.
Not even proper water shoes.

Then I looked around and realised how prepared all the Japanese families were.

They had wagons filled with tents, tables, chairs, cooler boxes, food, toys and everything they needed to comfortably spend an entire day beside the river.

That was when we started paying attention to all the little things that could make our next trip more comfortable.

By our second summer, we had bought our first outdoor wagon, camping chairs, table and cooler bag.

By our third summer, we had proper water shoes, kids’ swimming gear, cooling towels, a portable fan and all those little things you don’t realise you need until you’ve done it a few times.

And now, 川遊び has genuinely become one of my favourite Japanese summer activities to do with family and friends.

Why I love 川遊び in Japan

There’s something so nice about escaping Osaka during the hottest part of summer and heading into the mountains.

It can be ridiculously hot outside, but the moment you step into the river…

THE WATER IS FREEZING. 😂

You can swim, have a BBQ where permitted, eat beside the river, let the kids play and just spend the day surrounded by nature.

Over the past few summers, we’ve tried a few places around Kansai. These are three that stood out to me.

1. 清滝川遊び場所 — Kiyotaki River Play Area, Kyoto

This one feels the most natural and casual out of the three.

It’s less like going to a proper campground and more like finding a beautiful river spot, putting down your picnic mat and spending the day there.

I love how relaxed and local it feels.

But what I REALLY love about this place is that it isn’t only a summer destination.

Come back during autumn!

You’ll be surrounded by autumn leaves, and we’ve actually come back here just to picnic during autumn too. 🍁

The downside is that the facilities are much more basic, so personally I think this is better for families who are already quite comfortable spending a day outdoors without needing too many conveniences.

For me, this is the place for a simple day: picnic mat, chairs, food, water shoes and nature.

With young kids, I’d personally keep a closer eye on them because it’s a natural river environment rather than a managed swimming area.

My pick for: Nature + a simple picnic day
Bonus: Beautiful in autumn too 🍁

2. 荒滝キャンプ場 — Arataki Camping Ground, Osaka

Out of these three, this was probably the one I enjoyed most with my kid.

You get the proper Japanese summer experience here — set up your tent, bring food, have a BBQ where permitted, sit beside the river and spend the whole day there.

What I especially liked was the water when we visited.

A lot of the areas where my kid played were shallow.

When I went further in, I could actually swim while still being able to stand. I’m 162 cm, and in the deeper part where I was swimming, the water came to around my ribs/below my chest.

That meant I could enjoy swimming too while my kid played in the shallower area without me feeling stressed every second. 😂

Of course, this was only the condition during our visit. River depth and current can change depending on weather and rainfall, so please never use my experience as a guarantee of what the river will be like when you go.

The only disappointing part?

There weren’t that many fish. 😂

But if a family asked me which of these three I’d choose for their first 川遊び experience, this would probably be my pick.

One more tip: GO EARLY on summer weekends.

Parking and camping areas can fill up surprisingly quickly.

My pick for: First-timers + families
When we visited: Mostly shallow areas + some deeper swimming areas
Fish: Not many 🐟

3. 天川みのずみオートキャンプ場 — Tenkawaminozumi Auto Camping Ground, Nara

Now this one is completely different.

Of the three, this was the deepest and most adventurous river experience for us.

The water is BEAUTIFUL.

When we visited, we could see lots of fish swimming underneath us, and if you’re a confident swimmer, swimming while watching the fish below is such a nice experience.

But the current was also noticeably stronger and there were much deeper areas.

Because of that, I personally wouldn’t choose this one with a baby.

With an older toddler or child, I’d only feel comfortable if a confident adult swimmer was right there with them at all times.

It’s also a proper campground, so you have more facilities and it feels much more like going away for a proper summer outdoor day.

And one warning:

The water is COLD. 😂

Even when Japan is boiling hot, mountain river water can be surprisingly icy.

If I wanted beautiful water, fish and a little more adventure, this would be my choice.

But out of these three, it’s also the one where I would personally be the most cautious with children.

My pick for: Beautiful water + swimming + fish
When we visited: Deeper with a stronger current
With young kids: Extra caution

So, which one would I choose?

If it’s your first 川遊び with kids, I’d personally choose Arataki Camping Ground.

If I wanted a simple picnic surrounded by nature, I’d choose Kiyotaki — and definitely remember it again when autumn comes.

If I wanted beautiful water, fish and more swimming, I’d choose Tenkawaminozumi.

But honestly, where you go is only half of it.

After three summers of doing this, I realised that what you bring can completely change how comfortable your river day is.

Our first year = picnic mat.

Our third year = we practically move house for the day. 😂

Which is why I finally put everything we’ve learned into one checklist.
