Boso Biwa: Chiba's Short-Season Loquat Fruit

Loquat (biwa) grows particularly well in the warm, mild microclimate of the Boso Peninsula's Tateyama and Minamiboso areas, where orchards have cultivated the fruit for generations. Premium biwa is often grown under greenhouse cover to protect the delicate fruit from wind and frost, which pushes up cost but produces larger, more consistently sweet fruit than open-field growing. The season is notably short, generally clustering around May into early June.

Biwa is almost always eaten fresh, peeled and seeded by hand, its texture somewhere between a peach and an apricot with a delicate floral sweetness that doesn't hold up well to cooking or long storage. Because of its short shelf life and season, it's sold mainly through local farm stands and direct farm sales rather than distributed nationally in large volume, and premium specimens are frequently bought as a seasonal gift rather than an everyday snack.
