Genbe River, Shizuoka

4.7 (293)Tourist AttractionPoint Of InterestEstablishment

The Genbe River flows through the Izu Peninsula in Shizuoka Prefecture, carving a dramatic path through volcanic rock formations over thousands of years. Located in the town of Kawazu, this scenic waterway has become renowned for its striking geological features and crystal-clear waters that reveal the riverbed below. The river's name derives from the local dialect, and it has long been appreciated by residents for its natural beauty and the cooling respite it offers during hot summers.

The river's most distinctive feature is its basalt rock formations, created by ancient volcanic activity that shaped much of the Izu Peninsula. These dark, columnar rocks contrast beautifully with the emerald and turquoise hues of the water, creating a landscape that appears almost otherworldly. The Kawazu Seven Waterfalls (Kawazu Nanadaru) along the river's course showcase this geological drama, with falls ranging from 2 meters to 30 meters in height. The area's volcanic origins have also blessed it with numerous hot springs, making it a popular destination for combining natural sightseeing with onsen bathing.

Visitors can explore the Genbe River area via well-maintained walking trails that follow the water's edge and connect the various waterfalls. The Nanadaru Loop Bridge, a striking double-loop pedestrian bridge standing 45 meters tall, offers panoramic views of the forested valley and is particularly popular during autumn foliage season and early spring when kawazu-zakura cherry blossoms bloom in the region. Swimming and wading are popular activities during summer months, with designated areas where the water depth and current are manageable.

The nearest station is Kawazu Station on the Izu Kyuko Line, approximately 2.5 hours from Tokyo via the Tokaido Shinkansen to Atami and a local train transfer. From Kawazu Station, local buses run to the waterfall area, or visitors can take a 25-minute walk to reach the starting point of the trail. Admission to the riverside walking paths and waterfall viewing areas is free, though some facilities and parking areas may charge fees.

Genbei river was a fun excursion! I was riding the rented bike from my hotel and I thought I’d go site-seeing in the Mishima area. I first went to the Temple and did my routinary prayers to the gods. It was a short bike ride to the river, as soon as I got there and parked my bike, I heard the laughs of happy kids. There were families there who were cooling off from the very hot and humid sunday(34C). I took off my shoes and started walking riverside. It is not a big river,only about 4 meters wide and about 2 feet deep. It has a good current where kids can float on the floaties. The water was cold and refreshing and VERY CLEAN!! It was clear and it did not have any smells. What makes it all perfect is that the whole river was under a canopy of trees and there were lots of places to sit down and just relax. This quaint little river is worth the visit. =)

Small, shallow river with strings to walk through it. Good place to sit and relax

Water is clean and chilling, fun to play with it🍀
