Tagajo Ruins Iris Park and
Tagajo Ruins Iris Festival


This park is the largest of its kind in Tohoku, and it is carpeted with violet irises. During the rainy season, these cute purple flowers bloom as raindrops trickle off their petals and down their stems.

3 Million Irises


The Tagajo Ruins Iris Park is the largest such park in Tohoku; it features 800 varieties and 3 million blossoms. During peak season, a spectacular carpet of violet, indigo, and sapphire spreads as far as the eye can see. During the rainy season, the cute purple irises bloom as raindrops trickle off their petals and leaves. Each year, in mid- to late June, the Tagajo Ruins Iris Festival is held there for a weekend. Visitors can enjoy local performing arts and engage in many activities, such as trying on traditional garments and buying local gourmet foods.


Peak season is very busy, so at that time, it is best to access the venue by train or bus.

Founded in the Nara period, Tagajo is a historic town that developed as the capital of Mutsu Province. Here, you can engage with history that comes right from the textbooks in places such as the Tohoku History Museum, with exhibits that cover the Tohoku region from the Paleolithic period to the modern day, and the special historic sites of the Taga Castle Ruins, the Tagajo Temple Ruins, and the Tatemae Ruins. Also, volunteer guides lead a tour around the poetry monuments to tanka and haiku writers such as Matsuo Basho and the monument around the Teizan Canal, which Date Masamune left. I am in charge of promoting the Shiro no Murasaki brand, a new gourmet food brand from Tagajo that makes products by using ancient varieties of rice. The brand’s products are available in stores across the city, so come and taste this quality produce that is intertwined with the history of the area.

Tagajo produces a wide range of specialty produce—including ancient rice (black rice), which is a variety that is close to the original rice species; Chojuro nashi pears; and tropical orchids. In particular, the Shiro no Murasaki brand, which produces items with ancient rice, has created a variety of products—including rice, sake, and confectioneries.
