Asahi and Yokoshikabow: Canola Flower Fields of Chiba

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. Canola is the official prefectural flower of Chiba (designated in 1954), a true symbol of the region, and around places such as Sosa City the countryside is carpeted in brilliant yellow. The contrast of clear blue sky and vivid gold is a beloved seasonal signal that spring has arrived.

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. However, following a derailment in October 2024 the Isumi Railway has suspended services on the entire line and is running replacement buses instead (restoration is expected around autumn 2027), so you cannot currently ride the train itself. 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.
