After the war, oil was very scarce, but electricity was plentiful. For this reason, there was a period when the government promoted the manufacture of electric vehicles. With this encouragement, the "Tama" was introduced and earned a high reputation. In performance tests conducted by the Ministry of Commerce and Industry, it succeeded in bettering its catalog specifications with a cruising range of 96.3km and a top speed of 35.2km/h. It was used as a taxi and in similar roles until 1950.
