Abundant the sunshine is, the UV rays are quite weak, so you don’t need to worry that your skin will get hurt.

The downside is that daytime hours are a bit short, meaning a wise trip plan in advance is essential. Many local shops, restaurants, and even public transportation services close as early as 15:00 in winter. Therefore, it’s highly recommended to start your day early, check opening times in advance, and allow some extra time for waking, as Nikko’s best destinations tend to require you to walk a lot. 

Is Nikko Worth Visiting in January? 

Absolutely. January is a wonderful time to experience a different side of Nikko. The climate is cold and dry, but on sunny days, comfortable sunlight makes outdoor walks surprisingly pleasant. With snow covering its shrines, temples, and lakes, places like Toshogu Shrine, Rinno-ji Temple and Lake Chuzenji take on a magical and otherworldly charm. 

Another advantage is the quietness of the season. January is off-peak travel season in Nikko, meaning fewer tourists, more tranquil scenic spots, and lower hotel rates. If you’re looking for snowy landscapes but lower travel cost, compared with Hokkaido, Nikko offers excellent value: combining rich cultural heritage with breathtaking snow scenery.

As for footwear, non-slippery hiking shoes are essential for your trip, as the icy road can be dangerous.
