The park and other facilities on the island have been collaborating with Love Live! Sunshine!! since the series started, giving them boosted tourism numbers.
The Shizuoka District Court found in June 2021 that the bonds were an unjust enrichment, and on October 5, two 10 meter boats moored at the docks in Numazu were seized, which featured Love Live! Sunshine!! wrappings.
The Marine Park owned two other boats, but one was for employees to get to the island and another was moored elsewhere.
