Tokyo day trip to a beautiful secret beach in Chiba

Nagahama Beach, Chiba

Nagahama Beach is an impressive cliff beach located just north of the famous Onjuku township. The hike takes about 30 mins in total (see the maps below), and is well worth the effort. First, you need to walk about 10 mins on the dirt road towards Koura Beach. It’s possible to drive to Koura Beach, but the dirt road is narrow and often wet so a small 4×4 SUV is advised. Only a few small cars can park there at any given time. The hiking trail over the hill to Nagahama Beach starts from Koura Beach, and it takes about 20 mins. The trail is often overgrown with lush vegetation but there are ropes where slopes are slippery and narrow.

This is one of the beaches that is known as a “gay beach”, attracting this type over summer weekends. For those who want to have the beach just for themselves, it is best to avoid weekends during July/August. May/June and September/October are quiet times even at weekends, and we recommend especially September as it is still hot enough to enjoy this scenic beach with warm water.

While you are in the area, we also recommend checking out Onamitsuki Coast for the scenic views. There is a little waterfall on the left side of the beach.
There is a car park by the road where the path to Onamitsuki Coast starts.

Nagahama Beach is located under 2 hours from central Tokyo by car via the Tokyo Bay Aqua Line.
