Koyo: autumn leaves in Japan

Koyo (紅葉) is the autumn colour change — the moment when Japanese maples, ginkgos, and other deciduous trees turn red, orange, and yellow before dropping their leaves. In Japan it is one of the great seasonal experiences of the year, comparable to spring cherry blossoms, and it has its own culture of tracking, forecasting, and travelling to see it at peak.

Koyo and sakura: two different experiences

The parallel with cherry blossom is unavoidable — both last a short time, are unpredictable well in advance, and draw people who travel specifically to see them — but the experience is quite different.

Sakura is festive and social: groups sitting under cherry trees with food, drinks, and blankets. Koyo tends to be more contemplative. The most beautiful locations are usually temples, traditional gardens, and mountain paths where quiet is built in. The colour palette is also warmer and more varied than the white and pink of cherry blossom.

One practical difference: koyo lasts longer. A cherry blossom peak can end in a week with rain and wind. Autumn leaves hold for several weeks in dry weather, and the colour front moves slowly southward over weeks, giving more time to plan.

When it happens

Koyo starts in Hokkaido at the end of September and in the mountain areas of Honshu during October, then descends south towards the cities through October and November. In Tokyo and Kyoto the peak is usually in late November, though it varies year to year with temperature.

A rough guide by region:

• Hokkaido (Daisetsuzan, Sounkyo): late September / October
• Nikko, Japanese Alps: mid to late October
• Tokyo (Shinjuku Gyoen, Rikugien, Koishikawa Korakuen): late November
• Kyoto (Eikan-do, Tofuku-ji, Arashiyama): mid to late November
• Osaka, Nara: late November

To narrow down exact timing, the Japan Meteorological Agency and several specialist sites publish weekly koyo forecasts, similar to cherry blossom forecasts.

Best destinations

Nikko (Tochigi)

The temple and shrine complex at Nikko, surrounded by mountain forest, is one of the most spectacular and accessible koyo destinations from Tokyo. The train from Asakusa takes around two hours on the Tobu Nikko Limited Express. October queues can be long at weekends.

Arashiyama (Kyoto)

The bamboo and temple district west of Kyoto has some of the most photographed koyo in the country. Tenryu-ji, Jojakko-ji, and the path along the Oi River are the main points. It is one of the most crowded areas of Kyoto in autumn season.

Eikan-do and Tofuku-ji (Kyoto)

The two temples most famous for koyo in Kyoto. Eikan-do has a central pond that reflects the maples; Tofuku-ji has the Tsutenkyo, a covered bridge from which you look out over a sea of red leaves below. Both have long queues at peak season.

Rikugien and Koishikawa Korakuen (Tokyo)

The two best traditional Japanese gardens in Tokyo for koyo. Rikugien organises evening illuminations where the maples are lit from below — an entirely different experience from daytime koyo. Koishikawa Korakuen combines a well-preserved historic garden with views over the Bunkyo neighbourhood.

Sounkyo (Hokkaido)

The Sounkyo gorge in inland Hokkaido has particularly intense koyo in early October — the colours are more vivid than in Honshu because temperatures drop further. It can be combined with the onsen in the area.

Japanese Alps (Kamikochi, Norikura)

The high-altitude zones of the Japanese Alps have a koyo that starts much earlier than in the cities. Kamikochi, the glacial valley that closes to private vehicles, is especially beautiful in October with the maples and the Azusa River.

How to time your visit

Koyo forecast services work similarly to cherry blossom forecasts. They publish estimated start and peak dates by region and destination, updated weekly. The most reliable are from the Japan Meteorological Agency and the Weather News site (ウェザーニューズ).

The peak of koyo is called mankoyo (満紅葉), the moment when the largest number of trees are at their fullest colour. It lasts one to three weeks depending on conditions. Heavy rain and wind speed up leaf fall; cool, dry weather holds the colour longer.

A practical note

The most famous temples and gardens at peak season can have queues of over an hour on weekends. Going on a weekday, arriving early in the morning, or visiting lesser-known spots in the same destination are the three most effective ways to avoid crowds.

Koyo is also visible without going anywhere specific — urban parks, neighbourhood gardens, and riverbeds in cities have their own colour change, less dramatic but without the crowds of tourist destinations.
