Yuji's interest in fishing brought him to open a specialized lure & fly fishing store, "King Fisher" with his two other friends in 1980. At the same time, he start making his original handmade lures named "MARO". MARO lures soon got attention as their beautiful shapes and really "good" for fish. Especially its pencil type topwater lure, "MARO Pen", was a legendary killer lure for bass fishers.
MARO old lures are very rare because Yuji didn't make so many lures after 1990 due to his health problem.
