Naming rights Miyagi Stadium's name had remained unchanged since it opened in 1950. However, before the start of Rakuten's first season in Miyagi Stadium, the team and the prefecture agreed to sell the naming rights to the stadium to help pay for team management costs. The agreement stipulated that the rights would be renegotiated every three years and the money from the each contract would be split between the team and the prefecture at a three-to-one ratio, respectively. Additionally, any new stadium name must include the word "Miyagi". The first contract was awarded to the only bidder, staffing firm Fullcast, and in early 2005, the ballpark's name was changed to "Fullcast Stadium Miyagi" for ¥600 million.

In 2013, Nippon Paper decided not to renew its contract to purchase Miyagi Stadium's naming rights for a third time. Two companies applied after the prefecture opened applications, and Rakuten, the baseball team's parent company, was awarded the contract for ¥603 million. The ballpark was named "Rakuten Kobo Stadium Miyagi" from 2014 through 2016 to promote the company's ebook and e-reader subsidiary, Kobo Inc. When Rakuten renewed the contract at the end
