There are many reasons NOT to hike during the Japanese summer – it’s hot, it’s humid, and it’s damn difficult, so keep these tips in mind.
1 – It’s Humid!
Japan is known for having one of the most humid summer seasons in the world. Moisture is high and winds are low, but hiking up mountains is surprisingly not such a terrible idea. The shade from the trees provides protection from the sun (for the most part) and the higher up you go the more the humidity dissipates. You will be sweating buckets though, so be sure to wear your best sweat-friendly clothes.
2 – Bring Cash!
You’re going to be chugging down drinks like no tomorrow, because the Japanese summer works overtime to drain you of your body’s fluids. Having some cash on hand is critical to having access to vending machines that you come across along the way, particularly for those hikes that offer tourist attractions at the end, like souvenir shops and food stalls.
3 – Consider a Phone Charger
One thing I’ve noticed in extreme heat is that my phone’s battery drains just as fast as my energy levels (poor joke). If your phone is susceptible to overheating, you may find the battery dies way before its time, leaving you stranded with no Google Maps. I recommend bringing a portable battery charger or at least a USB cable that you can use at the nearest convenience store‘s charging ports.
4 – Aim for High Altitudes
If you’re going hiking in the Japanese summer, I highly recommend a mountain route, or at least one with a solid uphill ascent. This is because higher altitudes bring with it cool breezes, colder temperatures, and low humidity, all of which are Godsends during Japan’s heatwaves. My personal recommendations are Mt. Daimonji and Hieizan in Kyoto Prefecture.
5 – Avoid the Rainy Season!
It may be tempted to go dancing in the rain when it’s boiling hot outside, but I definitely don’t recommend hiking in remote mountains during a downpour. It can be extremely dangerous not just for losing your footing but some areas may be susceptible to floods. Not to mention, summer rain in Japan seems to have little to no effect on humidity and temperature, so don’t bank on it for a cooler hike!
