Piramid TARP setup.

In my previous article, I mentioned the importance of a high waterproof rating, but when camping in the rain, the shape of the tent can have just as much impact on your comfort.

It’s common sense: if a tent’s outer layer (rainfly) is shaped to let water flow off smoothly, you’ll have less to worry about regarding leaks, even if the waterproof rating isn’t exceptionally high.

The recently popular one-pole tents and canopy-style tents are prime examples of this.

These tents feature slanted sheets designed to naturally channel rainwater away, preventing it from seeping in.

These days, tarps have become a standard part of camping setups, but how you pitch them is incredibly important.

If you set up a tarp with large flat sections, rainwater will collect and increase the risk of it seeping through.

To ensure water drains efficiently, it’s crucial to create an appropriate slope when pitching your tarp.

When rain becomes heavy, water may accumulate on the roof of your tarp or tent, causing it to sag.

High-waterproof materials prevent seepage, but they can also hold more water, which increases the weight and could lead to a tarp or tent collapsing under the strain.

That’s a real danger.

I’ve learned this lesson the hard way in the past.

Since then, I’ve made it a habit to attach caps to the top of adjustable tarp poles, allowing me to push up from the inside and guide rainwater away.

Having at least one telescopic pole with adjustable length can be a lifesaver in situations like this.

In rainy camping conditions, you’ll often spend extended periods under your tarp or tent.

That’s why creating a spacious and tall area is another key to staying comfortable.

Being able to stand upright makes a world of difference.

If you’re stuck in a cramped space for hours, it can quickly become exhausting, but having a taller and more open area allows you to relax—even in the rain.

A larger space also provides more room to store your gear without getting it wet, making cooking and taking breaks much easier.

When camping in the rain, it’s not just about the design of your tent or tarp.

How you set them up and plan your time under them also requires creativity and preparation. Each small precaution you take can be the key to making the experience enjoyable.

One simple takeaway: whether in the outdoors or in life,

Camping always comes with a sense of uncertainty.

Outdoor adventures aren’t just about fun and excitement—they’re also filled with inconveniences and worries.

That’s the nature of camping: a mix of play and a certain type of “living.”

Isn’t life a lot like that?

One of the uncertainties that comes to mind is rain.

In the outdoors, weather has a huge impact.

The phrase "guerrilla rainstorm" has become familiar over the years, though recently it seems to have faded from common use.

Perhaps it’s on its way to becoming a thing of the past.

Rain is one of those inconveniences that can be a real hassle.

To stay comfortable on rainy days, a good tent or tarp is essential—something that can stand up to the rain.

One key factor in rain protection is the waterproof rating, which determines how resistant the fabric is to water penetration.

From my experience, for camping in Japan, a waterproof rating of 1,500mm to 2,000mm is sufficient to handle most rainy conditions.

It’s worth noting that when choosing overseas-made tents or tarps, you need to be careful.

Products designed for regions with less rain often have lower waterproof ratings.

In Japan, where rain is frequent, checking this spec is crucial.

Take Coleman, for example—a famous outdoor brand from the U.S.

I’ve heard that their products come in both Japanese and international versions.

One distinguishing feature of the Japanese models is their higher waterproof rating.

In the WeatherMaster Series by Coleman, the rainfly has a waterproof rating of around 3,000mm—50% higher than Coleman’s standard products, which are rated at about 2,000mm.

When I was younger, I used to think Coleman’s gear looked a bit "uncool."

Its waterproof performance seemed no match for brands like Snow Peak, and the designs didn’t stand out much.

But as I’ve grown older, my perspective has shifted.

Take Coleman’s signature white guy lines.

I didn’t like them at first, but now I see their value—they’re highly visible in the dark, which adds a layer of safety at the campsite.

The rope material is soft yet sturdy, striking a nice balance between ease of tying and durability.

Never judge solely by appearances.

Many times, I’ve learned to appreciate practicality over looks.

On rainy camping days, you’ll end up spending more time under your tent or tarp.

That’s when quality matters.

If the waterproof rating is low, you’ll constantly worry about leaks.

That’s why I aim for at least 2,000mm for rainfly and floor sheets—and preferably 3,000mm if possible.

This is especially important for the floor sheet when sleeping in the inner tent.

It needs to prevent water from seeping in, not just from rain but also from the ground.

A good groundsheet under the inner tent is also essential.

While any durable material works, I like to prioritize “atmosphere.”

Although utility tarps work fine, I prefer using dedicated groundsheets to complete the camping vibe.

This mindset stems from past experiences.

Once, I was camping at the Hirayu Campground in Gifu Prefecture.

A sudden downpour hit in the middle of the night, and the area around my tent turned into a river.

I had to retreat to higher ground, leaving the tent behind.

At the time, I was using a cheap tent.

It wasn’t exactly stylish—a basic model from the DCM brand—but its waterproof performance surprised me.

The floor material was as tough as industrial tarps, which kept all my belongings dry inside the tent.

That anxious, rainy night taught me an important lesson: always prioritize waterproofing when choosing a tent.

If there’s any takeaway from today’s story, it’s this:
