12 Must-Visit Recommended Tourist Spots in Iwakuni City, Yamaguchi Prefecture

Iwakuni City is located in the easternmost part of Yamaguchi Prefecture. The original, old Iwakuni City was known as the castle town of the Iwakuni domain under the Kikkawa clan during the Edo period, and after the return of political power to the Emperor, it became the Iwakuni Domain. Facing the sea, the area has also flourished in the fishing industry. Today, Iwakuni has become a famous tourist destination in the Chugoku region. This time, we will introduce some must-visit sightseeing spots in Iwakuni City.

1. "Iwakuni Castle" with a Great View

Iwakuni Castle was built by Hiroie Kikkawa. A bridge was constructed nearby, creating a uniquely beautiful scene that sets this castle apart from others. The town that spreads out below the castle is organized around the bridge, and the area is now known as Kikko Park.

It’s said to be a rare mountain castle in Japan, featuring the Momoyama-style Nanban architecture. About one-fourth of its lower portion is buried underground, and in 1995, the old-style Anō-zumi stone walls were excavated and restored. Some remnants still exist today, such as the stone walls of Kita-no-Maru and the empty moat. Currently, a ropeway connects the castle to the town. From the observation area on the 4th floor, you can enjoy panoramic views of the old castle town, the bridge, and the small islands of the Seto Inland Sea.

In 2006, it was selected as one of Japan’s Top 100 Castles. If you buy a combined ticket for Kintaikyo Bridge, the ropeway round trip, and Iwakuni Castle, you can get a discount—highly recommended! If you don't use the ropeway, you can hike about 2 km from Momijidani Park, but be careful as the path can be rough.

2. "Kintaikyo Bridge," Rich in Historical Value

Kintaikyo Bridge is designated as a "Place of Scenic Beauty." In the past, crossing the bridge was restricted by social class, and it’s said that ordinary townspeople were only allowed to cross after the Meiji era.

This wooden bridge is 193.3 meters long and 5 meters wide. Its construction was inspired by Hangzhou, and it was completed in 1673.

As you gaze at the clear stream below and look up, you can admire the bridge’s architecture—it's truly impressive.

They are actually albino mutations of the Japanese rat snake (Aodaisho).

It’s very rare to see a national natural treasure like the white snake up close. They’re also considered symbols of good luck, so this place is known as a spiritual power spot. Usually, they are calm and barely move, but sometimes they’re active even during the day.

Since it’s close to Iwakuni Castle and Kintaikyo Bridge, you can casually stop by during your sightseeing.

Additionally, in Iwakuni City, there’s a White Snake Shrine (Shirohebi Jinja). The deity, Uga Benzaiten, is said to have wrapped a white snake around herself, making her not only a bringer of fortune but also the goddess of music, learning, and many other blessings.

6. "Eboshidake" with a Hiking Course

The hiking course offers a beautiful contrast between the snow, plants, and the color of the sky. Though the trail is long, it’s relaxing and healing to walk. As you go along, you’ll come to a rest spot with a stone called "Niwatori Ishi" (Chicken Stone). The name comes from a story where ancient farmers, who woke up early every morning to work the fields on the mountain, took a rest there and heard the crowing of roosters as the sky brightened.

If you’re feeling tired from the climb, this is a great place to take a break. Afterward, you can proceed to the observatory, where the view from the shrine of the general is said to be unparalleled. On clear days, you can see as far as Shikoku and Kyushu. Though the climb is challenging, the scenery from the summit is well worth the effort.

10. Beautiful Autumn Views at "Momijidani Park"

Momijidani Park is famous for its autumn foliage and was developed on land that dates back to the Edo period. This area was once known as "Teradani" because of the many temples clustered here.
