Tohatsu, produced in Japan from 1950 to 1964, was a motorcycle manufacturer best known for its lightweight two-stroke motorcycles and scooters. Originally established as an engine and industrial equipment company, Tohatsu became one of Japan’s largest motorcycle producers during the 1950s, offering models such as the Runpet, Puppy, and Sports series. The brand gained recognition for reliable engineering, competitive racing success, and innovative small-displacement designs that were exported to international markets. Characterized by practical performance, durable construction, and strong postwar growth, Tohatsu ceased motorcycle production in 1964 to focus on marine engines and industrial equipment, sectors in which it remains active today.
