I stopped by while touring the hand-dug tunnels of the Boso Peninsula. There’s a walking path along the valley, so it’s a great spot for a stroll!

Yoro Valley
A fantastic hiking course through the valley of a waterfall.
This valley was formed by the Yoro River and sits at the very center of the Boso Peninsula in Chiba Prefecture. Located just 2 hours from Tokyo, this lush, nature escape in Chiba is also home to many different hot springs. The climate is generally mild, making it a great hiking destination in winter, and also earning the title “the latest autumn leaves in Kanto”, as they come into full color from late November to early December.
Yoro Valley is home to a rich array of nature, and “8 Scenic Points of Yoro”, which includes the biggest waterfall in all of Chiba Prefecture, the Awamata Waterfall. Additionally, gorgeous autumn leaves can be found across the area in spots like Umegase-keikoku Gorge and the historical artificial tunnel site, Kobundo Ruins.
There are 3 different hiking courses available at Yoro Valley. The 4-km “waterfall circuit course” has few slopes and a path that brings you to 5 different waterfalls. This easier course is great for beginners are hikers bringing kids.

Yoro Valley in Chiba is a famous spot for autumn leaves. I went with a few friends over the weekend, and it was really beautiful. It's super convenient—just a short drive from Tokyo. Walking along the valley, the air felt especially fresh.

I took the retro Kominato Railway train, and the station I arrived at was pretty small and old. It doesn't seem like a lot of tourists come here, and there aren't many shops or restaurants around. Luckily, I had some snacks with me to keep me going.
