The Exchange Festival also featured stage performances, outdoor tea service, hands-on activities, and vehicle displays.

Origins and History of Tagajo Ruins Iris Festival
The festival’s opening day and its connection with Matsuo Basho are introduced as part of the cultural background associated with irises.
It is said that, as Basho set out from Sendai for the Stone Monument of Tsubo on his journey along The Narrow Road to the Deep North, he composed the verse “I’ll tie iris blossoms to my feet—the cords of my sandals.”
In 2026, an iris-themed haiku contest was held in connection with this verse.
No detailed information on the festival’s founding year or history is available from the sources that could be verified.
