The story
NBK’s history dates to 1560, when Taro-Uemon-i Okamoto founded the company. In 1749, the Okamotos received from the Imperial Court a license as a caster. They presented the Kyoto Imperial Palace with a lantern and were given the trade name “Nabeya”, that means "Pan(Pot) shop or artisan". The Okamotos produced many temple bells in Japan. The main branch of the Okamotos runs Nabeya Co., Ltd. while other branches use “Nabeya” as part of the name of the company which they run. "Bi-tech" stands for "Newest and Traditional 2-technologies", and "Kaisha" means "Company or Corporation".
The company in its current form was incorporated by Tomokichi Okamoto in 1940.
