Nikko’s Week-by-Week Fall Color Calendar: From Senjogahara Down to the Historic Shrines

Every year around mid-September, I inevitably get the same question from friends: “When are the fall colors in Nikko at their best?” And every time, I have to answer with a question of my own: “What do you want to see in Nikko?” It may sound a little annoying, but it’s the right question. Nikko doesn’t have one fall-color season—it has an entire calendar that lasts more than a month, with the “main stage” moving to a different location each week.

The reason is elevation. The Toshogu shrine complex below the town sits at around 600m above sea level, while Yumoto Onsen at the top of the Okunikko area is nearly 1.500m high. A difference of nearly 900m means a difference of several degrees Celsius, and trees change color according to temperature: the high mountains get cold first, so the leaves turn first; the warmer town follows later. As a result, Nikko’s koyo “wave” moves steadily from high to low elevations, almost every year.

This is where many people get it wrong. I once met a group of friends who had eagerly gone to Nikko in early October, only to stand bewildered in front of Toshogu’s gates because the trees were still completely green—while just one bus ride away, Senjogahara marshland was glowing golden at its peak. Conversely, some people go up to Lake Chuzenji in mid-November, find that most of the leaves have already fallen, then head back down and are surprised to discover that the shrine area is at its best. This guide gives you that week-by-week calendar, along with a way to check the forecasts yourself and choose the right travel date.

Why Nikko Has an Entire “Fall-Color Calendar” Instead of a Single Season

Picture Nikko as a giant staircase. The top step is Yumoto Onsen and Senjogahara marshland, at an elevation of 1.400–1.500m. The middle step is Lake Chuzenji and Ryuzu Falls, around 1.300m. Connecting the middle and lower steps is the Irohazaka pass, with its 48 hairpin turns. The bottom step is Nikko town, with its World Heritage shrine and temple complex, at around 600m.

Autumn “descends” this staircase one step each week. Up high, the cold nights at the end of September are already enough to turn the grasses and shrubs. By the time the colors reach the lake, it is mid-October. By the time they reach the shrines, it is already November. Once you understand this rhythm, it is almost impossible to miss the season entirely—the only question is which step to choose for your week.

One note before we get into the detailed calendar: the dates below reflect the rhythm of a “normal” year. In recent years, warmer weather has tended to delay the color change by about a week, and the timing can still shift each year depending on whether cold weather arrives early or late. That is why the forecast-checking section at the end is just as important as the calendar itself.

Week-by-Week Fall Color Calendar: From High to Low

Late September – early October: Yumoto Onsen and Senjogahara Marshland

This is the opening act, and also the one that few international visitors know about. Senjogahara is a vast marshland at an elevation of around 1.400m, and the first thing to change color here is not the maple leaves but…the grass. The Japanese call this phenomenon kusamomiji—“grass autumn colors.” The entire marsh turns coppery yellow and then reddish brown, dotted with slender white-barked birch trees, with Mount Nantai in the distance. In the early morning, mist creates a quiet, subdued atmosphere that is very different from the brilliant koyo scenes you often see in photographs.

The best way to experience it is on foot. A wooden boardwalk crosses the marsh, and the most popular route runs from Ryuzu Falls uphill to Yudaki Falls and then onward to Yumoto Onsen, taking about half a day at a relaxed pace. The trail is mostly flat and does not require mountaineering fitness, but remember to bring warm clothing—by late September, early mornings up here are already as cold as early winter in Tokyo.

Finishing the walk at Yumoto Onsen is a smart choice. This small hot-spring village sits beside Lake Yunoko, whose mineral-rich sulfur waters are cloudy white. There is nothing better than soaking after a walk in the cold air. If you enjoy slow travel, staying overnight in Yumoto this week is far more rewarding than squeezing into the crowds during the October peak.

Mid–late October: Ryuzu Falls and Lake Chuzenji

This is the climax of the entire season, and also when Nikko is busiest. Ryuzu Falls—“Dragon Head Falls”—is one of the most famous spots in Okunikko at this time of year. The water splits over a rocky bed, while maples and other red-leaved trees cover both sides. Viewed from the base, it looks exactly like a dragon parting the water amid a sea of fire. There is a teahouse at the foot of the falls with seats facing directly toward the view; arrive before 9 a.m. and you can take your time, but after that you may have to wait quite a while just to get a photo.

Lake Chuzenji sits at an elevation of around 1.270m, with a broad surface and Mount Nantai rising majestically on one side. The lake’s peak week usually falls in the second half of October. You can take a sightseeing boat, cycle or walk along the shore, and visit two historic villas that once served as vacation homes for the Italian and British embassies. Sitting on the wooden veranda and looking out over the leaf-streaked lake is, in my view, one of the most beautiful autumn scenes in the Kanto region. Nearby, Kegon Falls plunges nearly a hundred meters straight down a cliff, and an elevator takes visitors to the observation deck at its base (there is a fee, so check the official website for information before you go).

For a view from above, set aside time for Hangetsu Pass south of the lake. The lookout over the Hatchodejima Peninsula jutting into the water is a classic viewpoint for autumn at Lake Chuzenji.

Late October – early November: Irohazaka Pass

As the colors around the lake begin to fade, they blaze anew along the pass connecting Okunikko with the town. Irohazaka consists of two one-way roads—one uphill and one downhill—with a total of 48 hairpin turns. Each turn is named after a character from the old kana syllabary. During the fall-color season, the mountainsides on both sides seem to be on fire, and every bend reveals a new scene.

On the uphill route is the Akechidaira Ropeway, which takes you to an observation deck offering views of Lake Chuzenji, Kegon Falls, and the sea of foliage below all at once. Many people consider this the best view in Nikko. The ropeway may stop operating in strong winds or for maintenance, so check its operating status beforehand.

I should be frank about the downside: traffic jams on Irohazaka at this time of year are “legendary.” On peak weekends, a stretch of pass that normally takes twenty minutes can take several hours, and buses get stuck just like private cars. My advice is to go on a weekday if possible. If you have to go on a weekend, leave Tokyo very early and reach the pass before 8 a.m., or go much later, after 3 p.m., and stay overnight around the lake. The middle of the day is the worst time.

Early–mid November: The Shrine District and Town Center

This is the finale of the season, and for many people, the best part. By now, the fall colors have reached the World Heritage shrine and temple complex—Toshogu, Rinnoji, and Futarasan—as well as the red Shinkyo Bridge over the Daiya River. Red maple leaves against gilded shrine gates and vermilion walls create the kind of “very Japanese” scenery you cannot find in the mountains. In November, the low afternoon sun filtering through the maple canopies in the shrine grounds is indescribably beautiful.

This is also the easiest week for getting around. Everything is near the town center, accessible on foot from the station or after just a few bus stops, and you are not dependent on Irohazaka Pass. Outside the shrine area, spend an hour walking into Kanmangafuchi—a small riverside gorge lined with Jizo statues wearing weathered red knitted caps. In the leaf-fall season, golden leaves cover the paths, and the area is much quieter and more peaceful than the main shrine district.

A small tip: early November is the most beautiful overlap period of the year. If you go during exactly this week, you can head up Irohazaka in the morning to catch the last of the leaves on the pass, then come back down to the shrine area in the afternoon for the beginning of its own color season—two completely different scenes in one day.
