Sengoku Seisakusho Co. Ltd., Nagoya city 1956-59
Sengoku Seisakusho produced 50cc moped machines using a Toyo Motor's engine. The model was called the Cyclone (サイクロン), or Cyclone Pet (サイクロンペット) depending on which source you reference. The company started as a joint venture with Toyo Motors, but between 1956 and 1959 operated as its own entity. Production stopped when the plant and production machinery were badly damaged in the Ise Bay Typhoon in the third week of September 1959.
