Complete Guide to Morioka Castle Ruins Park (Iwate Park) | History, Highlights, and the Charm of All Four Seasons Explained in Detail
Morioka Castle Ruins Park (Iwate Park), located in the center of Morioka City, Iwate Prefecture, is a historical park developed on the site of Morioka Castle, which was the residence of the Nanbu clan. The landscape, where beautiful stone walls harmonize with nature that changes with the seasons, has been selected as one of “Japan’s 100 Historical Parks” and is cherished as a place of relaxation for residents. This article provides detailed explanations of the history of Morioka Castle Ruins Park, its highlights, event information, and access methods.
What is Morioka Castle Ruins Park?
Morioka Castle Ruins Park is an urban park located at 1-37 Uchimaru, Morioka City, Iwate Prefecture. It is a park developed on the ruins of Morioka Castle, a hirayamajiro (castle built on a hill) that was built on a granite ridge jutting out at the confluence of the former Kitakami River and Nakatsugawa River. The park was opened as “Iwate Park” in 1906 (Meiji 39). To commemorate the 100th anniversary of opening in 2006 (Heisei 18), it was given the nickname “Morioka Castle Ruins Park,” and today it is known by both names.
The park covers approximately 10.6 hectares, and the beautiful stone walls built with Morioka granite tell of the castle’s former appearance. Because of the beauty of these stone walls, Morioka Castle is counted as one of the “Three Famous Castles of Tohoku” along with Shirakawa Komine Castle and Aizuwakamatsu Castle.
Currently, under the designated management system, the NPO Green Consultation Room manages and operates the park, and it is open to residents and tourists throughout the four seasons.
The History of Morioka Castle Ruins Park | Historical Changes
Construction of Morioka Castle
The history of Morioka Castle dates back to 1597 (Keicho 2). Nanbu Nobutao (the first lord of Morioka Domain) decided to relocate his residence from Sannai to Kozukata and began construction with his eldest son Toshinao (the second lord) as the chief overseer of the project.
The construction work took approximately 36 years and was completed in 1633 (Kanei 10) during the time of the third lord, Nanbu Shigenao. It was a hirayamajiro that took advantage of the natural fortress provided by two rivers—the Kitakami River and Nakatsugawa River—and consisted of the main enclosure, second enclosure, third enclosure, and other fortifications.
Morioka Castle did not have a keep tower; instead, a three-story turret was constructed in the main enclosure. This is also said to have been out of consideration for the Edo Shogunate.
Changes After the Meiji Era
After the Meiji Restoration, Morioka Castle came under the administration of the Military Ministry in 1874 (Meiji 7), and most of the buildings were torn down. However, the stone walls and ponds and other remains were preserved, and in 1906 (Meiji 39), the site was developed and opened as “Iwate Park” according to a design by Yasuhei Nagaoka, a landscape architect representing the modern era.
It was designated as a national historic site in 1937 (Showa 12), and the nickname “Morioka Castle Ruins Park” was established in commemoration of the 100th anniversary of opening in 2006 (Heisei 18). During the Great East Japan Earthquake in 2011 (Heisei 23), part of the stone walls suffered damage with some collapse, but restoration work has progressed, and conservation activities continue today.
Highlights of Morioka Castle Ruins Park
Beautiful Stone Walls
The greatest highlight of Morioka Castle Ruins Park is, without question, the stone walls built by stacking granite from Morioka. The stone walls, which reach heights of approximately 8 meters, employ techniques such as “nozura-tsumiage” (stacking natural stones as they are) and “uchikomse” (stacking stones with worked angles), allowing visitors to see the advanced construction techniques of that era.
The stone walls of the main enclosure in particular are impressive, and visitors can truly understand why Morioka Castle is counted as one of the “Three Famous Castles of Tohoku” based on their beauty and sturdiness. Grass and moss peeking through the gaps in the stone walls convey a sense of historical weight and are popular photography spots.
Spots Within the Park
Main Enclosure Ruins
The main enclosure ruins, at the highest point of the park, are where the three-story turret once stood. Currently developed as a plaza, it has become a viewpoint from which one can overlook the city of Morioka. In spring, cherry blossoms bloom in profusion, making it a famous cherry blossom viewing spot that draws large crowds.
Second Enclosure Ruins

This monument has become a pilgrimage site for Takuboku fans.
Miyazawa Kenji Poetry Monument
A poetry monument by Miyazawa Kenji, a fairy-tale author and poet from Hanamaki, is also located in the park.
