2026-09-06 · 分鐘閱讀
10 月是日本隱藏的最佳旅遊季。天氣完美、紅葉開始、萬聖節、飯店半價。各地天氣、活動、7 日行程完整整理。
Japan in October is the season most first-timers miss — perfect 20°C days, first koyo colors starting, hotels 40% cheaper than sakura or GW. If you have flexibility, October is arguably the best month.
October 2026 weather by region
| Region | Avg High/Low (°C) | Rain days | Notes |
|---|---|---|---|
| Hokkaido (Sapporo) | 15 / 6 | 8 | Early autumn colors, snow possible late month |
| Tohoku (Sendai) | 19 / 10 | 10 | Peak koyo late October, hiking season |
| Kanto (Tokyo) | 22 / 15 | 9 | Perfect walking weather, koyo starts late |
| Kyoto/Kansai | 23 / 15 | 8 | Ideal — before crowds, after summer heat |
| Chugoku (Hiroshima) | 23 / 15 | 7 | Miyajima gorgeous, low tourist counts |
| Kyushu (Fukuoka) | 24 / 17 | 7 | Late autumn arrives here, ramen season |
| Okinawa (Naha) | 27 / 22 | 8 | Still summer-warm, snorkeling last month |
Autumn foliage (koyo) timing in October
October is the START of Japan's koyo season, not the peak. Peak moves south from Hokkaido to Kyushu over 2 months. In October 2026, expect these zones:
- ●Sept 20 – Oct 5: Daisetsuzan (Hokkaido) at peak — first koyo of the year
- ●Oct 10 – Oct 25: Kamikochi, NikkoPR starting to change
- ●Oct 25 – Nov 5: Towada/Oirase (Aomori), Karuizawa fully color
- ●Late October only: Tohoku mountain regions at peak
Kyoto and [Tokyo](https://www.booking.com/searchresults.html?ss=Tokyo) koyo does NOT peak in October — expect just first color changes late-month. If you're going in October for koyo, target Nikko, Karuizawa, or Kamikochi. For Kyoto/Tokyo koyo, come in November.
Major October 2026 events
| Date | Event | Location |
|---|---|---|
| Oct 4-6, 2026 | Nada no Kenka Matsuri (fighting shrine festival) | Himeji |
| Oct 7-9 | Nagasaki Kunchi | Nagasaki |

| Throughout Oct | Tokyo Ramen Show (Komazawa Park) | Tokyo |
| Mid-Oct | Ebisu-ko Festival (Osaka Tenmangu shrine) | Osaka |
| Late Oct | Halloween ramp-up (theme parks + Shibuya) | Nationwide |
| Oct 30-31 | Peak Halloween week (Roppongi, Shibuya) | Tokyo |
| Oct 22 (holiday) | Jidai Matsuri (Kyoto historical parade) | Kyoto |
Hotel pricing sweet spot
October is Japan's hotel bargain window. Same KyotoPR hotel:
| Period | Kyoto Karasuma (mid-range) | 預訂 |
|---|---|---|
| Sakura peak (early April) | ¥55,000-70,000/night | 🏨 預訂 |
| Golden Week (early May) | ¥60,000-80,000/night | 🏨 預訂 |
| **October 2026 (early half)** | **¥18,000-25,000/night** | 🏨 預訂 |
| November koyo peak (Nov 25-Dec 5) | ¥45,000-70,000/night | 🏨 預訂 |
| December off-peak | ¥25,000-35,000/night | 🏨 預訂 |
Early-mid October is 60-70% cheaper than sakura. If you're flexible on when to visit, October is the objective best-value window (only rainy-season June is cheaper, but October has better weather).

Why October beats other months for value
- ●vs. March-April (sakura): October is 60% cheaper, similar weather, less crowded
- ●vs. November (koyo peak): October cheaper by 40%, koyo starts (not peak) in most spots — but pre-crowd
- ●vs. December: October is warmer + more daylight
- ●vs. Summer (July-Aug): October is 10-15°C cooler, no humidity, no typhoons (September-typhoon-season ends)
October Japan packing
- ●Layers: 18-24°C daytime → 12-15°C night. Bring a light jacket + one warm sweater
- ●Comfortable walking shoes (autumn hiking possible in NikkoPR/Karuizawa)
- ●Rain jacket (~9 rain days per month across regions)
- ●Camera + spare battery (koyo photos require lots of shots)
- ●Halloween costume if in TokyoPR Oct 30-Nov 1 (optional but recommended)
The one October risk to know
October is technically still typhoon season — typhoons occasionally hit Japan in early October (mid-month is safer). Book flexible-cancellation hotels + travel insurance. AirlinePR delays possible if typhoon crosses the country. Otherwise: October is Japan's best-kept-secret travel month.
