The October Timing Trap: Why Your Foliage Plan Decides Your Whole Trip
Here is the catch nobody flags clearly: the autumn colour you booked Japan for in October is mostly not in the cities yet. Tokyo and Kyoto stay green through the month and only peak in late November, so if red maples are the goal, October sends you north. Daisetsuzan National Park in Hokkaido is the country's earliest koyo, turning from mid-to-late September and dropping to lower elevations by early October, while Kamikochi in the Northern Alps peaks roughly mid-October into early November. Plan the trip around where the leaves actually are, not where the photos were taken.
The weather itself is the easy part. Tokyo runs around 23C by day and 16C overnight, humidity falls off sharply after summer, and skies are often clear. Crowds and prices sit near average, below the cherry-blossom and New Year peaks, so a three-to-four week booking window usually holds.
Two honest cautions:
- October is the tail of typhoon season, averaging about 1.7 storms approaching the country, so build a flexible buffer day and keep refundable bookings.
- The Takayama Autumn Festival (Hachiman Matsuri) runs October 9 to 10 at Sakurayama Hachimangu Shrine, free to watch but packed, so reserve Takayama lodging early.

Japan in October: autumn colour & comfortable days
October is one of Japan's best-kept secrets — the koyo (autumn foliage) begins in the northern highlands and mountains, the punishing summer humidity is gone, and the crowds are far thinner than cherry-blossom season.
Weather & what it's like
Crisp and comfortable — 15-22°C, clear skies, ideal for walking. The maples flame red in the mountains first (Hokkaido, the Japan Alps) before the colour reaches the cities in November.
Crowds & events
Quieter and cheaper than spring. October brings harvest festivals, the Takayama Autumn Festival (early October) with its ornate floats, and matsutake mushrooms and persimmons on every menu.
What to pack
Layers and a light jacket for cool evenings; comfortable shoes for foliage walks.
