Visiting Koyasan During the Rainy Season (Tsuyu) – What to Expect in June and July

If you’re planning to visit Japan between June and mid-July, you might hear the term “Tsuyu” (梅雨)—Japan’s rainy season. And yes, Koyasan experiences it too. But don’t let the word “rain” stop you. In fact, Koyasan in the rainy season is one of the most peaceful, mystical times to visit.

What Is Tsuyu – Japan’s Rainy Season?

Tsuyu, meaning “plum rain,” marks a seasonal transition when gentle, steady rainfall spreads across much of Japan. In mountain towns like Koyasan, the rain brings a unique beauty: mist-covered forests, quiet trails, and vibrant green moss covering ancient stone paths.

While the skies may be grey, the experience is anything but gloomy. Many travelers say Tsuyu is their favorite time to visit Koyasan for its calm, spiritual atmosphere.

Why You Should Visit Koyasan in the Rainy Season

Wondering if it’s worth visiting Koyasan during Tsuyu? Here’s why it might be the perfect time:

• Mystical Landscapes: Okunoin Cemetery becomes even more atmospheric with mist, glistening stone lanterns, and moss-covered gravestones.
• Fewer Tourists: Enjoy Koyasan’s temples and sacred trails in peace, without the usual crowds.
• Cooler Temperatures: While the rest of Japan can be hot and humid, Koyasan stays relatively cool—sometimes even chilly—during this time.

Tips for Enjoying Your Trip During the Rainy Season

What to Pack

• Compact umbrella or lightweight raincoat – Most rain is light but frequent.
• Waterproof or non-slip shoes – Paths can be wet and slippery.
• Warm layer or light jacket – Mornings and evenings can be unexpectedly cool.
