The mandarin orange cultivation in the Arida region is a traditional agriculture that has been passed down for over 400 years in a natural environment with many mountain forests and few harvests from flat fields. It is considered one of Japan's agricultural heritages. The terraced mandarin orange fields along the Arida River, especially those near the summit of Yamadahara, provide a picturesque view during the harvest season when the mountains turn orange and offer a splendid panoramic view of the Arida River estuary and Arida City.

Arida City is an area with a high number of tourists visiting the fish market in Wakayama, serving as a home port for small-scale boat bottom trawling, Seto Inland Sea boat bottom trawling, and single-line fishing.

The "Minoshima" brand, in particular, is well-known. At Minoshima fishing port, a fleet of yellow "Utase-sen" boats returns around 3 p.m., with numerous carts waiting at the port to transport fresh fish for auction.
