On the Kumano Kodo in July, 'Humidity' Is Tougher Than 'Heat'

July on the Kumano Kodo is the time of transition from the end of the rainy season into full summer. The timing of the end of the rainy season varies year to year — some years are rainy throughout, while others bring strong sunshine from early on.

What you tend to feel most on the old trails in this season is not so much the temperature itself, but the humidity. Cedar and cypress forests offer plenty of shade and feel cooler than sunlit areas, but in spots where the wind doesn't flow through, the air stagnates and sweat starts to trickle out just from walking.

So when planning your July outfit, instead of only thinking about "how to stay cool," it works better to think about "how to release sweat and how to let it dry."

The Basics: Quick-Dry, Lightweight, and Light Colors

Tops: Quick-Dry Short Sleeves or Thin Long Sleeves

Cotton T-shirts feel comfortable to wear, but once they soak up sweat they're slow to dry, and your back tends to feel cold every time you rest. Quick-dry T-shirts made of synthetic fibers like polyester, or thin dry-material tops, are reliable choices.

If you're concerned about sunlight, brushing against plants, or insects, thin and breathable long sleeves are also recommended. A combination of short sleeves plus a thin outer layer makes it easier to adjust to changes in heat.

Bottoms: Easy to Move In and Quick to Dry

On trails with many stone steps and uneven surfaces, there will be moments when you need to lift your legs high. Stretchy, quick-drying pants will be easier to walk in. Shorts that are too short can leave you worrying about grass, insects, and scrapes.

Footwear: Prioritize "Non-Slip Even When Wet"

In July, stone paths after rain and mossy spots can become slippery. Choose shoes with soles that have solid grip, and go for thin, quick-dry socks that release sweat easily. On days when you'll be walking longer, having a spare pair of socks will make a real difference in how you feel.

Three Things That Are Easy to Overlook

① Sun Protection: Hat and Around the Neck

Even on trails with continuous shade, you'll be exposed to strong sunlight on ridges and in open areas. In addition to a brimmed hat, having a thin towel or something like a neck cooler to protect your neck will give you peace of mind.

② Insect Protection: Long Sleeves and Repellent

On summer mountain trails, mosquitoes, biting midges, and horseflies can become a nuisance. Along with wearing clothing that reduces skin exposure, having insect repellent on hand lets you walk with greater ease.

③ Preventing a Chill from Sweat: Bring a Change of Clothes

Even though you feel hot while walking, when your sweat cools down at your destination you may find yourself surprisingly chilly. So you can change before visiting a shrine, going to an onsen, or waiting for a bus, it's comfortable to keep a dry T-shirt in your backpack.

Dealing with Rain

July is a season when you should also plan for sudden rain. Rather than an umbrella, a lightweight rain jacket that leaves both hands free is better for walking. However, wearing rain gear on a muggy day can make the inside steamy with sweat, so in addition to "staying dry," it's worth keeping "ventilation" in mind.

What to Avoid: Dressing Too Lightly Just Because It's Hot

Outfits that prioritize only coolness — such as tank tops or sandals — can lead to sunburn, insect bites, and the risk of falling. The Kumano Kodo trails are closer to nature than city walks. Keep the balance between coolness and safety in mind.

Hydration and Rest Go Hand in Hand

Even if you have the right outfit, your body won't feel at ease without enough hydration. Sip a little water before you feel thirsty, carry trail snacks that replenish salt and sugar — managing the heat basically means thinking about hydration together with your clothing. Don't push yourself; take frequent breaks in the shade.

Summary: In July, Think "Dry," "Protect," and "Change"

If you keep these three in mind, walking the old trails will become much more comfortable even in muggy July. The deep green and the moist air are a face of Kumano unique to summer. Dress reasonably and take your time to savor it.
