Japan's autumn foliage (koyo) season runs October through December and rivals cherry blossoms in raw visual drama — scarlet maples, golden ginkgos, and crimson sumac against temple rooftops and castle walls. Unlike spring, the season lasts six weeks as colors sweep south from Hokkaido, giving more opportunities to catch peak color.
When Does Koyo Peak?
Hokkaido: late September to mid-October. Nikko / Tohoku: mid to late October. Tokyo: mid to late November. Kyoto / Osaka: mid-November to early December. Hiroshima / Western Japan: late November to mid-December. Peak colors last 1–2 weeks per location; watch the Japan Meteorological Corporation's koyo forecast from September.
Best Spots in Kyoto
Eikan-do (Zenrin-ji): Kyoto's single best koyo temple — vermillion maple canopies over a lotus pond, evening light-up (momiji-akari). Queue from 4pm. Tofuku-ji: Famous maple garden — dramatic gorge of red maples visible from the Tsuten-kyo bridge. Arrive at opening (8:30am). Arashiyama: The mountains surrounding the bamboo grove turn red-orange; Tenryu-ji garden gains extraordinary depth. Rurikoin: Limited-access garden in Yase, only open spring and autumn — the lacquered table reflecting maple trees is one of Japan's most photographed images. Book in advance.
Best Spots in Nikko
Nikko (2 hrs from Tokyo) peaks in mid-October — earlier than anywhere else within day-trip distance. Iroha-zaka: Switchback mountain road lined with maples — spectacular by bus or rental car. Chuzenji-ko: The crater lake at altitude with reflections. Toshogu Shrine: Cedar avenue plus surrounding maple forest — deeply atmospheric in autumn light.
Best Spots in Tokyo
Shinjuku Gyoen: Late autumn (mid-November to December) — one of the few parks with enough variety to show color past late November. Rikugien: Edo-era garden with a central weeping cherry that transforms into a weeping maple canopy; beautiful night light-ups. Koishikawa Korakuen: Compact but dense garden with maples over a central pond. Ginkgo Avenue, Meiji Jingu Gaien: 146 ginkgo trees form a yellow tunnel — peak typically second week of November.
Underrated Koyo Destinations
Sounkyo Gorge (Hokkaido): Remote, early, and genuinely spectacular — towering basalt cliffs in full red and orange, late September. Karuizawa: Resort town 1 hr from Tokyo with dense mountain forests — late October. Daisen (Tottori): The "Mt. Fuji of western Japan" — beech forests in full autumn color, almost no foreign tourists. Korankei (Aichi): 4,000 maple trees in a river valley, lit at night — one of Japan's most intense koyo concentrations.
Practical Tips
Accommodation books out as fast as cherry blossom season in popular spots — reserve Kyoto in late November 3+ months ahead. Weekday mornings are dramatically less crowded at temples with paid entry. Light rain enhances colors and creates reflections. A telephoto lens compresses foliage layers beautifully; a wide angle works best for lone trees against clear sky.
