Why Nasu Oosawa Is One of Japan's Best Autumn Foliage Destinations

Every autumn, the highlands of Nasu Oosawa transform into a breathtaking canvas of red, orange, and gold. Because of its elevation — the highlands sit at between 600 and 900 metres — the colour change begins earlier here than in the lowlands, and the dramatic contrast between fiery foliage and the dark volcanic slopes of Mount Nasu creates scenes that are hard to forget. Koyo (紅葉), the Japanese tradition of appreciating autumn leaves, reaches its peak in Nasu Oosawa typically in mid-to-late October.

When Do the Leaves Change?

Autumn colour timing varies by year depending on summer temperatures and rainfall, but as a general guide:

Area / Elevation Typical Peak Period
Mount Chausu summit (1,900m+) Late September to early October
Nasu Ropeway upper station (~1,684m) Early to mid-October
Nasu Oosawa highland plateau (~700-900m) Mid to late October
Lower areas and valleys Late October to early November

This staggered progression means that, across a few weeks, you can follow the colour change down from the summit to the valley, extending your viewing window considerably.

Best Spots for Autumn Leaves in Nasu Oosawa

Nasu Ropeway and Mount Chausu

The ropeway ride itself offers spectacular views of the autumn-coloured slopes. From the upper station, the landscape of crimson dwarf azalea, golden larch, and rust-coloured grass stretching toward the volcanic peak is genuinely spectacular. This is the most iconic autumn image of Nasu, and draws large crowds — weekends in mid-October can be extremely busy.

Otome no Taki Waterfall Area

The forested valley around Otome no Taki (Maiden's Falls) is framed by maple and beech trees that turn vibrant shades in autumn. The combination of cascading water and autumn colour makes this one of the most photogenic spots in the region. The short trail to the falls is suitable for most visitors.

Nasu Shrine Approach

The cedar-lined approach to Nasu Shrine is flanked by deciduous trees that provide vivid seasonal colour. The contrast between dark, ancient cedars and bright autumn leaves creates a uniquely atmospheric scene. Evening lighting events are sometimes held here during the foliage season.

Highland Ranch and Open Pasture Areas

The open ranch and farm areas on the highland plateau offer wide, sweeping views of autumn-coloured hillsides — perfect for those who prefer easy, flat walking while enjoying the scenery.

Planning Your Autumn Visit

  • Book accommodation well in advance. Autumn is the busiest season in Nasu Oosawa. Ryokan rooms, especially those with rotenburo, sell out weeks or months ahead. Aim to book at least 2 months before your intended stay.
  • Avoid peak weekend traffic. The roads into the highlands become severely congested during autumn weekends. If possible, visit on a weekday, or plan to arrive very early (before 8am) to secure parking near the Ropeway.
  • Layer up. October temperatures on the highlands can drop sharply in the evening and morning. A warm layer and windproof jacket are essential.
  • Combine with a night stay. The highland plateau is magical at dusk and dawn during foliage season. Staying overnight lets you experience the landscape without the daytime crowds.
