Chiba Canola Fields, Boso Painted Yellow in Spring

Blessed with a mild climate, Chiba Prefecture becomes one of the Kanto region great flower destinations each spring, when canola blossoms burst into bloom across the Boso Peninsula.

Highlights

Warmed in winter by the Kuroshio current, the Boso Peninsula is known for flowers blooming earlier than in much of Honshu. In the earliest spots, canola begins to open in late winter and reaches its peak through spring. A member of the mustard family, canola was once widely cultivated for rapeseed oil and is deeply woven into the rural landscape; today it is often planted for scenery and tourism, making it one of the signature flowers of spring in Chiba.

One popular place to enjoy the blossoms is along the Isumi Railway, a rural line crossing the Boso Peninsula. The sight of its yellow train rolling slowly through fields of canola is a favorite among railway fans and photographers, who line up their cameras each spring. At Sakura Furusato Hiroba in Sakura City, canola and tulips bloom before the areas symbolic Dutch windmill in a scene like a painting, while at Mother Farm a hillside is said to be covered with around 3.5 million canola blossoms, easy to combine with other sights.
