Onbashi at Taishakukyo

Straddling Shobara City and Jinsekikogen Town in Hiroshima, Taishakukyo is an 18 kilometer gorge carved by the Taishaku River and designated a national scenic site. In its Kami-Taishaku area stands Onbashi, a huge natural arch bridge said to be about 90 meters long, 19 meters wide, and 40 meters high. Shaped as river water wore away limestone over an unimaginable span of time, it is designated a national natural monument in its own right, separately from the scenic designation of the gorge. Called the bridge of the gods for its grandeur and counted among Japan's noted bridges, it is a power spot where you can feel the force of nature.

Highlights

• Onbashi, the enormous natural bridge created by nature. Its towering scale makes you feel the beauty of a form built up over ages and the greatness of natural power.
• The walking path along the gorge. A trail of roughly six kilometers is maintained, and strolling this route wrapped in clear streams and greenery refreshes body and mind.
• Shinryuko, an artificial lake formed by the Taishakugawa Dam. Sightseeing boats operate on the lake, letting you enjoy from the water the scenery woven by the surface and the cliffs.

Enjoying the Seasons

In the fresh green season the whole gorge is wrapped in vivid greenery, making the walking path pleasant. Autumn is known as a foliage spot, and the autumn leaves reflected on Shinryuko are splendid. Summer draws people seeking the coolness of the gorge, and the view from the sightseeing boat is popular. In winter snow can make some sections harder to walk, so it helps to be prepared for snowy paths.

Access and Basic Information

• Location: Tojo-cho and other areas, Shobara City, Hiroshima
• Access: About 20 minutes by car from the Tojo Interchange on the Chugoku Expressway. From the Kami-Taishaku parking area you walk the path toward Onbashi.
• Hours: Free to explore
• Admission: Free (some facilities such as parking and the sightseeing boat charge a fee)

Practical Travel Notes

• Best season and time: The foliage peak is roughly early to mid November. To avoid crowds, early morning is the sweet spot.
• Time needed: To enjoy the round trip to Onbashi and a stroll around the Kami-Taishaku area, allow about half a day for comfort.
• Avoiding crowds: Parking fills up on autumn weekends, so an early arrival is recommended.
• Nearby spots: Scenic points in the gorge include Shinryuko and its sightseeing boat, and the Hakuundo limestone cave (paid). Kami-Taishaku and Shinryuko are far apart, so a car is assumed for visiting both.
• Budget sense: The stroll itself is free. Using the boat, the cave, or parking adds up to roughly a few hundred to around a thousand yen.

A Quick Tip

Since reaching Onbashi means walking the path, comfortable shoes are recommended. The Kami-Taishaku and Shinryuko areas are separate, so plan around a car to move between them efficiently. Footing in the gorge can be slippery depending on the weather, so take special care after rain.
