Izu Climbing

It is the famous Kawazu-zakura that begins to bud from early to mid-February, just as the Tohi-zakura petals have fallen. Among the early-blooming cherry blossoms, it is perhaps one of the most well known. This variety is called Kawazu-zakura because its original tree stands in Kawazu, in eastern Izu near Shimoda. However, these cherry trees are not limited to Kawazu or even to Izu—they have been planted in many other places as well, bringing vivid color to this still-chilly season.

Although the blossoms can be enjoyed in many regions, it is best to visit Kawazu itself, the source of this variety.

Since it takes only about a week from the start of blooming to full bloom, timing your visit can be difficult. Still, the uninterrupted row of cherry trees stretching several kilometers along the Kawazu River from its mouth is well worth seeing. Cherry trees are planted throughout the town, so it’s best to wander freely and follow your instincts. You may stumble upon unexpectedly magnificent blossoms tucked away in a quiet back alley.

You can reach Kawazu directly from the Ito area via the Izu Kyuko Line. However, if you are making the effort, it is highly recommended to head south along National Route 135, which runs along the eastern coast of Izu.

The distance from Odawara to Kawazu is 84 km. Though it follows the coastline, the route is a continuous series of ups and downs, with a total elevation gain of around 1,000 meters. It may not be an easy ride, but on a clear day you can see Izu Oshima floating in Sagami Bay, as well as the Izu Seven Islands further to the south. The views make the effort worthwhile.

Another option is a route that crosses Amagi Pass from Shuzenji:

This route heads south through the heart of the Izu Peninsula and becomes a hill climb over the Amagi Tunnel. The climb from the Shuzenji side is relatively gentle at first. There are two roads—Routes 414 and 349—which eventually merge at Yugashima, a hot spring area. Route 349, with lighter traffic, is recommended. If you wish to stop at the Tsukigase roadside station along the way, simply cross the Kano River to reach Route 414. At this roadside station, you can enjoy light meals such as the Shuzenji Burger (with fried amago trout) and soba noodles—making it a pleasant rest stop.

After passing Yugashima, the gradient begins to steepen, though it generally stays around 6% and does not become overwhelmingly severe. During the climb, you may want to stop at Joren Falls, a scenic waterfall. However, to see the falls up close, you must descend and climb a considerable number of stairs on foot, so proper walking shoes are essential.

Further up, you will find the Amagi-goe roadside . From there, it is less than 2 km to the peak at Amagi Tunnel. It may be a good place to take a break.

Once you pass through the Amagi Tunnel, it is downhill all the way to Kawazu. Be careful, as some sections have gradients of around 10%. As you descend through the mountains, a massive loop-shaped bridge will eventually come into view. Known as the Kawazu Nanadaru Loop Bridge, this double-loop structure eliminates a 45-meter elevation difference in one dramatic sweep—an experience rarely found elsewhere. Kawazu-zakura trees are planted along the inner slopes of the loop.

Near the loop bridge is an area that provides access to walking trails connecting the seven waterfalls known as Kawazu Nanadaru, and it is also a hot spring district. Izu is famous for its wasabi, and here you will find Wasabi-en Kadoya Shokudo, well known for its “wasabi-don” (rice topped generously with fresh wasabi). It is a popular restaurant, and you may have to wait up to an hour at times, but if you have the time, it is well worth trying—provided you don’t mind the sharp kick of fresh wasabi.

After passing the loop bridge, the gradient becomes gentler as you gradually approach the town of Kawazu. When you catch sight of the rows of cherry trees lining the Kawazu River, follow the riverside promenade and enjoy the blossoms at your leisure.
