Adenophora takedae or Iwasyazin (Scientific name: Adenophora takedae) is a deciduous perennial herb native to Japan, belonging to the genus Adenophora in the familyCampanulaceae. It is a wildflower that grows wild on rocky terrain in the mountains of the Kanto to Chubu regions of Honshu.The grass is 30-70 cm tall and has thick rhizomes but thin stems and leaves. The rhizomatous leaves are nutritive, ovate, and alternate. The leaves attached to the stem are narrowly lanceolate to broadly linear, 7-15 cm long, and have serrated edges.

The pistil of the pistil does not protrude from the bell-shaped corolla. The flowers are followed by a capsule.
