Overlooking the peaceful bay of Nachikatsuura, the Tsunagood Observation Space at the Tuna Museum introduces visitors to Japan’s deep bond with the sea. From this spot, you can watch fishing boats that have shaped the town’s life for generations. Exhibits link marine science with local tradition, explaining how tuna became a symbol of skill and sustainability in Japanese fishing culture. Through displays and short films, you’ll learn about tuna’s incredible speed, migration, and the responsible methods used to catch them. The space also tells how Nachikatsuura rose to become Japan’s leading tuna port. Tsunagood is not just an observation deck—it’s a window into the harmony between the sea’s energy and human craftsmanship

Just steps from the harbor, the Katsuura Fish Market Nigiwai Ichiba is the lively heart of Nachikatsuura. Each morning, the air fills with the scent of the sea as fresh tuna is unloaded and sliced by expert fishmongers. Visitors can taste local culture through maguro-don, a tuna rice bowl that captures the town’s pride. Small stalls sell regional delicacies and handmade goods, reflecting the warmth of coastal life. More than a marketplace, Nigiwai Ichiba celebrates the cycle of sea and community—a place where the story of tuna continues from ocean to table, inviting travelers to savor the authentic flavor of Wakayama’s maritime heritage.
