Introduction

  In 2020, the Roller Coaster activity started at the Koryo Festival held at Oyama Kosen. The next year, however, the Koryo Festival did not give permission for the public to ride the roller coaster, so the public was not allowed.

  In 2022, the coaster "Eagle," which was built for the third Koryo Festival, was finally manned and operated for the general public. The results were amazing, and more than 180 people were able to ride the coaster during the two-day operation. The Koryo Festival ended with a great success, receiving much praise not only from the visitors but also from the faculty members of the school.

  The scale of the coaster has expanded every year, and while the total budget for 2020 was approximately $660, the budget for 2022 was over $4,600. At the Koryo Festival 2022, the Shimotsuke Shinbun, a local newspaper in Tochigi Prefecture, interviewed us and published our work in the newspaper.
  Furthermore, a professor of Oyama Kosen and others suggested that the "Eagle" produced in 2022 could be preserved and that activities after the Koryo Festival could be carried out. As a result, we were able to obtain the cooperation of a kind-hearted person who lent us his private property, which made it possible to preserve the work and smoothly carry out activities after the festival.
  In addition, a company run by an alumnus of Oyama Kosen offered to sponsor the event, and we decided to participate in the "Oyama-ichi" event in Oyama City.
