This is the third consecutive year that the collaboration event will be held, and this time, cute and slightly wild Sumikkogurashi will appear in the museum dressed as various sharks, the "top predators of the sea." In addition to the keyword rally around the shark tank and exhibition corners in the museum and the special exhibition of creatures living in the corners of the seashore, this year we will also be holding a new event to search for Sumikkogurashi hidden in the museum! Of course, we will also be selling limited collaboration goods and food. Let's make lots of fun memories this year too!
