A field of 1.5 million sunflower plants in full bloom is attracting tourists to the city of Hokuryu in eastern Hokkaido.

Some of the plants in the 23-hectare field, one of the largest of its kind in Japan, are about 2 meters tall.

Visitors can also enjoy navigating a maze created in the field.

"They are blooming, growing straight up," Mai Hishinuma, a tourist from Toyoda, Aichi Prefecture, said Sunday. I feel uplifted when I see those flowers."

The best time for viewing will be around the middle of this month, after which the bright yellow flowers will start to wither.
