Nyuzen Jumbo Watermelon and Melon: Brand Flavors Nurtured by the Kurobe River

Nyuzen Town in Shimoniikawa District, Toyama Prefecture, is known for prized produce raised on the alluvial fan of the Kurobe River. Above all, the Nyuzen Jumbo Watermelon, which can grow more than thirty centimeters long and weigh over ten kilograms, is a nationally famous brand crop. Melons and other fruits are also actively cultivated here, and many people visit in search of the juicy, sweet flavors born of Northern Alps snowmelt and the fertile soil of the fan.

Bounty Raised by the Kurobe River Fan

Nyuzen Town spreads across a vast alluvial fan formed by the Kurobe River, which rises in the Northern Alps. Snowmelt from the mountains flows underground as subsurface water and wells up to nourish the town, making this a land blessed with pure, abundant water and well suited to agriculture. A large day-night temperature difference and well-draining soil raise sweet, juicy fruit. The Nyuzen Jumbo Watermelon is said to have been cultivated since the Meiji era, and over many years its varieties and growing techniques have been refined. It is a local pride, the fruit of natural bounty and the effort of farmers.

The Season for Jumbo Watermelon and Melon

The Nyuzen Jumbo Watermelon is distinguished by its large, barrel-like shape resembling a rugby ball, with thin rind and crisp, elegantly sweet flesh. Its sheer size makes it popular as a gift and a conversation piece. It comes into season in summer and is shipped through local farm stands and the agricultural cooperative. Melons also reach their peak from early summer into summer, offering a rich aroma and melting sweetness. When harvest season arrives, seasonal fruit lines the shelves of the town farm stands, which bustle with shoppers seeking the freshness and flavor found only at the source.

A Charm Best Enjoyed at the Source
