Kaikyo Plaza is located in the center of the Mojiko Retro area.
In addition to restaurants where local meals can be enjoyed such as baked curry and kawara soba noodles, there are many shops selling items such as sundries, seafood, and souvenirs.
The rich array of products include banana-flavored sweets unique to the place where "banana auctions" originated, and antique goods befitting a retro town.
