This project takes you on a journey to the sea through manga. The sea of adventure, the sea where love blossoms, the sea that nurtures food, and the sea that receives memories and prayers. A wide variety of seas are depicted in manga. Turning the pages brings both distant and unknown seas much closer. Rereading with the perspective of how the sea appears will lead to new discoveries, and focusing on the feelings entrusted to the sea will reveal a different kind of enjoyment in the stories. From works selected in collaboration with manga museums and researchers nationwide, please enjoy the breadth and depth of the sea connected through manga.
