In ancient times, the Tohoku region was known as "Emishi," where people with a culture distinct from the Yamato Imperial Court in Kyoto and Nara lived. To extend its influence, the Yamato Court established Tagajō City as a strategic base, marking the frontier in their conflicts with the Emishi. After the battles ended, Tagajō remained an important administrative center as the provincial capital of Mutsu Province.
Today, Tagajō City is a treasure trove for history lovers, preserving numerous historical sites, ancient artifacts, and valuable documents from that era. If you're passionate about history, this city is a must-visit destination!
In this article, we will introduce five must-visit tourist spots in Tagajō City, where you can immerse yourself in its rich historical legacy. Plan your trip and step back in time to discover Japan’s ancient past!
1. Tagajō Ruins
One of the top historical attractions in Tagajō City is the Tagajō Ruins. This site is the most significant historical landmark in the city and serves as the foundation of Tagajō City’s name. Unlike the castles commonly associated with the Sengoku period, featuring tenshukaku (castle towers) and stone walls, Tagajō functioned primarily as an administrative center to govern the region.
Constructed in 724 AD, Tagajō later became a strategic base for military operations against the indigenous Emishi people. It served as the provincial capital of Mutsu Province, playing a crucial role in the region's politics and culture for centuries.
Covering approximately 1 square kilometer, Tagajō was surrounded by 5-meter-high walls, ensuring protection against external threats. Within these walls stood various government buildings, military barracks, and administrative offices. While the original structures no longer exist, stone foundations and markers indicate where these buildings once stood.
Remarkably, Tagajō predates Kyoto’s Heian-kyō, which became Japan’s capital later in history. At the time, Japan’s major governing centers included Heian-kyō (Kyoto), Dazaifu (Fukuoka), and Tagajō, highlighting its importance as a key administrative hub.
Today, the Tagajō Ruins are well-preserved and have been transformed into a historical park, cherished by locals and visitors alike. Conveniently located just a 15-minute walk from JR Tagajō Station, it is an easily accessible site for tourists exploring Miyagi Prefecture.
If you’re visiting Tagajō City, don’t miss the chance to explore this ancient site and immerse yourself in Japan’s early history.

2. Tagajōhi (Tagajō Monument)
The Tagajō Monument (Tagajōhi) is a historically significant stone monument located near the entrance of Tagajō in Miyagi Prefecture, Japan. This ancient monument is one of Japan’s Three Great Stone Inscriptions and holds immense historical value.
Believed to have been erected in 762 AD to commemorate the reconstruction of Tagajō, this monument dates back to the Nara period—one of Japan’s most culturally significant eras. For centuries, scholars debated its authenticity, but it has since been confirmed as a genuine artifact from the Nara period. Today, the stone monument is well-preserved within a protective structure, emphasizing its importance.
The people of that time must have recognized the historical significance of Tagajō’s construction, just as we do today when we build commemorative monuments for major developments. Thinking about how people over a thousand years ago had similar customs makes history feel closer and more tangible.
When visiting Tagajōhi, consider discussing its history and cultural impact with your fellow travelers—it's a wonderful way to appreciate Japan’s rich past.

Tagajō Ayame Garden is a scenic iris garden located within the historic Tagajō Ruins. With approximately 3 million irises and Japanese irises (hanashōbu) in full bloom, the garden transforms into a breathtaking spectacle from June to August. During peak season, the vibrant purple hues of the flowers create a mesmerizing landscape, making it a must-visit destination.
A highlight of the garden is the Tagajō Ruins Ayame Festival, held annually from late June to early July. This festival offers visitors the chance to purchase irises and hanashōbu, while numerous food stalls and vendors line the pathways, creating a lively atmosphere. Additionally, a specially set-up stage hosts dance performances, singing shows, and other cultural events, drawing both locals and tourists.

4. Tatemmae Ruins
Taga Castle served as an important government office during Japan’s ancient era, which means that government officials worked there. The Tatemmae Ruins is an archaeological site located on a small hill southeast of Taga Castle, once the residence of high-ranking officials such as the provincial governor—equivalent to a modern-day prefectural governor.
As expected, top officials had the privilege of living in prime locations close to their workplace. Excavations have uncovered the remains of a four-sided eaves building, indicating the grandeur of the residence. If you visit the Tatemmae Ruins, take a moment to stand atop the hill and imagine the perspective of an elite official gazing over the bustling town of Taga Castle centuries ago.

5. Teizan Canal
The Teizan Canal (貞山運河, Teizan Unga) is Japan’s longest canal, stretching from the Abukuma River in Fukushima Prefecture to Ishinomaki City in Miyagi Prefecture. Originally constructed under the orders of Date Masamune, a powerful feudal lord of the Sengoku period, the canal was later extended through several construction projects to reach its current form.
The canal's name, Teizan, comes from the posthumous name of Date Masamune, who once ruled this region. Today, the Teizan Canal serves as a historical landmark and a must-visit destination for history enthusiasts exploring Tagajo City, Miyagi Prefecture.
