Sharp Drop in Rainfall

Nikko in October is much drier compared with the summer months. Rain tends to come as short showers, with the average monthly precipitation of 159 mm over 17 rainy days. Based on the data from the previous five years, Nikko in October rarely saw more than 47 mm in a single day.

Appropriate Humidity Level

Less rain means clearer skies, and the average humidity level remains approximately 79 %, which is perfect for outdoor adventures in Nikko.

Sunshine Hours & Daytime Hours

Sunshine Hours: about 5 hours
Sunrise: 5:36-6:03
Sunset: 16:45-17:25
Daytime Hours: 10 hours 42 minutes - 11 hours 49 minutes

With fewer rainy days, sunshine hours creep up to about five hours per day, and UV levels stay mild, with a maximum UV index of 5. A cap or walking in the shady path is usually all you need to stay comfortable under the sun.

One drawback is the shorter daylight hours. By late October, you’ll have less than 12 hours of daylight. Due to this, bus services to the mountain areas shut down unexpectedly early - for example, the last bus to Kirifuri Highlands leaves around 16:30. If you’re planning a hike for the autumn views, set out early and return to central Nikko before nightfall.

Is October a Good Time to Visit Nikko?

Definitely yes! October is one of the best times to visit Nikko.

Firstly, October combines the best of Nikko’s climate - mild temperatures, fresh air and less rain. Plus, October is the prime season for viewing fall leaves: maples and ginkgo trees paint the land, temples and shrines in brilliant shades of red and gold.

Yes, it is indeed busy, but compared with Tokyo or Kyoto, Nikko still is far less crowded during the fall foliage season. The balance of beauty and less overcrowding is exactly what makes October such a rewarding time to visit Nikko.

What to Wear in October

Upper Clothing: Due to cooling-down temperatures, you are advised to wear warm sweaters paired with jackets: practical and stylish.

Bottom Clothing: Jeans are suitable for a casual stroll in Nikko. If you plan a moderate hike in the mountain area, you’d better choose hiking pants or sweatpants to stay cozy. It’s a wise move to pack thermal underwear, just in case.

Footwear: A pair of non-slip hiking shoes is usually enough for your visit.

Accessories:
Rain happens occasionally, so rain gear is necessary.
A peaked cap and sunglasses are helpful for protecting your eyes from the UV rays and also for cool photos.

Top Fall Foliage Viewing Spots in Nikko

1. Ryuzu Waterfall

Early October is the best time to catch the red leaves, and it’s usually less crowded compared with other scenic spots. The ceaselessly flowing waterfall framed by bright red maples creates a dramatic contrast of motion and stillness.

2. Lake Yunoko

A well-established walking trail circles the lake, making it an ideal spot for families with kids and seniors to enjoy the foliage at a leisurely pace.

3. Lake Chuzenji

Japan’s highest natural lake offers both mountain and water views in full autumn color. You may take a boat to float over the lake with Mt. Nantai glowing in shades of red and gold, or take a hike up on the mountain itself for a close view of the red leaves and a bird’s eye view of entire lake.

4. Nikko Tamozawa Imperial Villa Memorial Park

For those seeking for a quieter spot, this former imperial retreat is a hidden gem. It’s such an enjoyment to stroll through the elegant gardens while admiring both the ancient architecture and the brilliant autumn leaves, with far fewer crowds.

Travel Tips

1. Book early. October is peak season, and accommodations sell out quickly.
2. Start your day early. You’ll avoid the heaviest crowds and have a better sightseeing experience.
3. Skip the weekends. Weekdays are noticeably quieter and the travel cost is relatively lower.
4. Take traffic into consideration. The Irohazaka Winding Road gets jammed as early as 7:00 during the fall foliage viewing season. A drive that normally takes 20 minutes can stretch to 3 hours, which proves early starts are essential again.
