They made beautiful bikes back in the days. I do not know them at all nowdays. The brand was a well known BMX brand, and the bike Elliot used in the movie ET was a Kuwahara. I think there was a Kuwahara MTB team in the mid/late 80s.

Kuwahara was founded in Osaka, Japan in 1918 by Sentaro Kuwahara. It was a family run business with help from his wife and eight children that made and sold bicycles and bike parts at first in his neighborhood, then growing and expanding more. In 1925 Kuwahara began to export bicycles and parts to Russia, China and Southeast Asia. Kuwahara closed their doors for business temporarily from 1940 till 1945 due to World War II. In 1947 Kuwahara reopened again for business and Sentaro Kuwahara became the first chairman of the board of directors of the first bicycle wholesale association in Japan. In 1959 the very first and small shipment of bicycles were delivered to the USA. Sadly in 1960 founding company president Sentaro Kuwahara passed away and his Son, Masao Kuwahara took over in his place. In 1962 Kuwahara sent it's first shipment of APOLLO brand sport (10speed or 12speed road racing) bicycles to Canada. In 1968 Kuwahara started exporting bicycles to the USA as private label bikes for other companies such as Schwinn, Takara, Puch, Concord, Apollo, Azuki and others. Kuwahara had never produced their own Kuwahara brand bike outside of Japan until 1972 when Kuwahara began developing BMX bicycles for the US, Canada, European and Australian markets. During the middle 1970's the BMX boom had started and Kuwahara was regularly exporting Kuwahara brand BMX's to these countries.
