The old saying “fuel, rice, oil, salt, sauce, vinegar and tea” shows the importance of “salt” in daily life. However, in Japanese colonial period, it required license to sell salt! With dispensary system, the government at the time could control business behavior. It could not be sold randomly as nowadays. Thus, the shop with license was the specialty store at the time!
