Japan in September 2025: Cool Weather, Fewer Crowds & Peaceful Travel

Japan in September

With summer crowds fading and autumn’s beauty just beginning to show, Japan in September is the perfect in-between season. Travelers who choose September are often rewarded with quieter sights, better value, and a relaxed pace that’s hard to find in peak months although September is one of Japan’s most overlooked travel months.

Why Visit Japan in September?

Compared to the busy April cherry blossom season or October’s autumn foliage rush, September feels calm. Shrines and gardens that would be packed later in the year are easier to enjoy at your own pace. Hotels and tours are often more affordable, and you’ll still catch seasonal events like Tsukimi, Japan’s moon-viewing tradition.

It’s also a month of transition. The energy of summer festivals lingers, but the atmosphere shifts toward autumn’s serenity. You can still enjoy warm weather without the intensity of mid-summer, and sightseeing feels less exhausting.

Weather in September

The first part of the month can still feel summery, especially in cities like Tokyo and Osaka. By mid to late September, the humidity eases, and daytime temperatures settle in the low 20s°C (mid-70s°F). Evenings are cooler, making strolls through historic districts or riverside walks especially pleasant.

It’s true that September falls within Japan’s typhoon season. While this may sound daunting, most visitors find it doesn’t disrupt travel much. Rain showers tend to be short-lived, and planning with some flexibility—mixing indoor visits with outdoor exploration—works best. Many museums, cultural centers, and shopping districts provide comfortable options on wetter days.

Where to Go in September

  • Kyoto – This ancient capital feels especially peaceful in September. Stroll through temple gardens like Kiyomizu-dera or Nanzen-ji without the heavy tourist traffic of later autumn. Cafés and tea houses highlight seasonal sweets made with chestnuts or early autumn matcha, offering a taste of the shifting season.
  • Nikko – North of Tokyo, Nikko is one of the first places to show hints of autumn color. Its shrines, waterfalls, and forested trails feel tranquil, and the cooler air is refreshing after the summer heat. September is a wonderful time to see its UNESCO-listed temples before peak foliage draws larger crowds.
  • Norikura Highlands (Nagano) – For those who love nature, the Norikura Highlands provide crisp mountain breezes, wide views of the Japanese Alps, and trails with far fewer people than October. Hiking here in September feels like having the mountains to yourself.
  • Hakone – Just outside Tokyo, Hakone is a classic getaway for hot springs, art museums, and views of Mt. Fuji. In September, the air is clear enough on some evenings to catch the harvest moon rising over Mt. Fuji—a magical connection to Tsukimi season.
