Kimisarazu Tower is an observation tower located in Ota-yama Park in Kisarazu City, Chiba Prefecture. Built as a symbol of the famous legend of Yamato Takeru-no-Mikoto and Ototachibana-hime, the tower is one of Kisarazu’s recognizable landmarks.
At the top of the tower, bronze statues of Yamato Takeru and Ototachibana-hime stand facing each other, representing the tragic love story associated with Kisarazu. The tower has also been selected as one of the “100 Best Night Views in Japan” and among the “100 Best Scenic Viewpoints in Chiba”, making it a popular destination for both daytime sightseeing and evening views.
Kimisarazu Tower was completed in March 1992 as part of the national Furusato Creation Initiative and to commemorate the 50th anniversary of Kisarazu’s incorporation as a city.
Although it stands close to the urban center of Kisarazu, the tower is surrounded by the greenery of Ota-yama Park and is located on the summit of the hill, providing an excellent vantage point over the city and Tokyo Bay.
The tower stands on the summit of Ota-yama, approximately 44 meters above sea level. The observation platform is about 11.7 meters above ground, while the entire tower is approximately 28 meters tall.
From the observation platform, visitors can enjoy a 360-degree panoramic view. On clear days, the view extends across Kisarazu and Tokyo Bay toward distant landmarks including Tokyo Tower, Yokohama Landmark Tower, and the skyscrapers of Shinjuku.
The tower also has a distinctive silhouette when viewed from below. Its shape was inspired by the Kisarazu boats that historically traveled between Kisarazu and Edo, present-day Tokyo, during the Edo period. Some descriptions also compare its form to a sword.
The name “Kimisarazu” is traditionally associated with the tragic love story of Yamato Takeru and Ototachibana-hime.
According to the legend, Yamato Takeru encountered a violent storm while crossing the sea. In order to calm the storm and allow him to continue his journey, Ototachibana-hime sacrificed herself by throwing herself into the sea. Yamato Takeru was overcome with grief and is said to have remained in the area for some time rather than leaving.
The place therefore became associated with the phrase “Kimi sarazu”, meaning roughly “the one I could not leave behind” or “you did not leave.” This story is traditionally connected with the name Kisarazu.
However, the legend is generally regarded as a later literary tradition rather than a confirmed historical explanation of the place name. Other theories have also been proposed, including possible connections with the Ainu word “kisara,” meaning “ear,” and with kisago shellfish. The true origin of the name remains uncertain.
The observation platform offers changing scenery throughout the year. The combination of Kisarazu’s urban landscape, the greenery of Ota-yama Park, and the broad waters of Tokyo Bay creates a particularly attractive panorama.
On clear days, visitors may be able to see landmarks on the opposite side of Tokyo Bay, including Tokyo Tower, Yokohama Landmark Tower, and the high-rise buildings of Shinjuku. The wide view makes the tower an enjoyable stop for photographers and travelers interested in seeing the relationship between Kisarazu and the Tokyo Bay area.
To the west of the tower lies the rice-growing area of Nagasuka. In ancient times, this region was home to the Gion-Nagasuka Kofun Group, a collection of ancient burial mounds.
The group included large keyhole-shaped kofun and the Kinreisuka Kofun. These archaeological remains provide an additional connection to the long history of the Kisarazu area and make the landscape visible from the tower particularly interesting for visitors fascinated by ancient Japanese history.
Kimisarazu Tower is especially popular after sunset. At night, the bronze statues of Yamato Takeru and Ototachibana-hime are illuminated, creating a romantic atmosphere that reflects the legendary love story behind the tower.
Because of this atmosphere, the tower has become a well-known date spot for couples as well as a place to enjoy the nighttime scenery of Kisarazu and Tokyo Bay.
In August 2004, Kimisarazu Tower was selected as one of the “100 Best Night Views in Japan.” It was also featured in 2011 on TV Asahi’s Yajiuma TV! as the top destination in a feature about night views associated with romance.
The tower is located along Chiba Prefectural Route 23, Kisarazu-Sueyoshi Line.
Visitors arriving by car can use the on-site parking area, which has space for approximately 68 vehicles. Parking is free of charge.
Kimisarazu Tower is a distinctive landmark where the scenery of Tokyo Bay meets one of Japan’s best-known ancient legends. During the day, the observation platform offers a broad panorama extending across Kisarazu and, in favorable weather, toward Tokyo, Yokohama, and the surrounding region.
After dark, the illuminated statues of Yamato Takeru and Ototachibana-hime give the tower a completely different atmosphere. The combination of legend, architecture, panoramic views, and nighttime scenery makes Kimisarazu Tower an appealing destination for travelers exploring Kisarazu.
When visiting Chiba, consider adding Ota-yama Park and Kimisarazu Tower to your itinerary for a chance to enjoy both the natural surroundings and the stories that have shaped the cultural identity of Kisarazu.
