Yoro Valley (Otaki Town, Chiba Prefecture)

Overview (history, characteristics, attractions)

Yoro Valley is a valley area in Otaki Town, Isumi District, Chiba Prefecture, and is a tourist destination where you can enjoy clear streams, steep rock formations, and natural scenery that changes with the seasons. A beloved local spot since ancient times, it is particularly known as a famous spot for viewing autumn leaves, with the colorful maples and Japanese maples decorating the valley in autumn. Dotted with waterfalls such as Awamata Falls, walking trails along the streams, and hot springs (Yoro Onsenkyo), the area offers a variety of ways to enjoy the area, from day trips to overnight stays.

Things to be aware of (crowds, manners, seasonal precautions, etc.)

• congestion:It gets very crowded during the autumn foliage season (around November) and on long weekends. Parking lots and buses fill up quickly, so we recommend leaving early in the morning or visiting on a weekday.
• Clothing and equipment:The trail is uneven and muddy in places, and has steep steps, so it is recommended to wear non-slip shoes (such as trekking shoes) and comfortable clothing. It can become especially slippery after rain.
• Nature Conservation and Manners:Please be sure to take your trash with you and avoid damaging vegetation or rocks. Please refrain from camping or making open fires in mountain streams without permission.
• Safety management:When the water level rises, the current can be fast and dangerous. Please take basic safety precautions, such as not getting too close to the river, keeping an eye on children, and avoiding walking alone.
• traffic:Public transportation is limited, so please check the return time before making your plans. Some sections of the road are dark at night.
• Insects and Wild Animals:In the summer, you need to take measures against insects (insect repellent, long sleeves, etc.), and in mountainous areas you also need to be careful of ticks.

Note: Timetables and parking/facility operating information may change depending on the season and year. Please check the latest information on the Otaki Town Tourism Association or the official websites of local facilities before making your plans.
