Access

Trade the urban hustle for a tranquil canyon adventure in one of Chiba's most picturesque natural settings.

Nestled in Otaki Town, Yoro Valley offers visitors a captivating blend of geological wonders and carefully maintained walking trails set within dramatic natural terrain. Set within a naturally formed landscape, the valley is dotted with hot springs in the surrounding area.

The valley's centerpiece is the taki-meguri waterfall walking route, beginning near the main river's source. Accessible by bus or taxi from Kazusa Nakano Station or Yorokeikoku Station on the scenic Kominato Railway, the route features the magnificent Awamata Waterfall—a massive, gently sloped cascade where visitors can wade in the shallow basin at its base. The paved 2-kilometer path continues downstream past additional waterfalls clinging to towering cliffs, making for an easy yet adventurous loop perfect for all fitness levels.
As of February 2026, the Takimeguri Promenade is accessible only for about 100 meters from the upstream (Awamata Falls) side, where visitors must turn back. Entry from the downstream (Kozawamata) side is currently prohibited. At Awamata Falls, visitors may stroll only in the immediate vicinity of the falls. Otaki Town also has three promenade routes. On the Nakase Promenade, the Kyoei Bridge side has been closed since December 12, 2025 due to tree-clearing work, while approximately 100 meters of riverside walking is available from the Kannon Bridge side. The Omojiro Gorge Promenade is open for walking as usual.

Starting from Yorokeikoku Station, you can explore additional routes including the popular Bungalow Village and Kobundo-ato Course. This trail leads to the fascinating Kobundo-ato ruins—a former natural arch carved into rock at the convergence of two rivers, which collapsed in the 1970s. Along the way, the vibrant Kannondo Bridge provides a stunning focal point against the valley backdrop, while steep stairs lead up to Rikkokuji Temple and the scenic Nakase Promenade.

The valley transforms seasonally, with dense summer greens giving way to spectacular autumn foliage that draws photographers and nature lovers alike. While the area sees many visitors, it rarely feels overcrowded. However, do plan to bring food or eat beforehand, as dining options are limited and popular spots can have long waits.

For the complete experience, consider staying overnight at one of the valley's traditional inns, where fresh local cuisine and hot spring baths await after your day of exploration. The Yoro Valley proves that Japan's natural beauty extends far beyond its famous mountains.
