George Takei reveals: Mr. Nakamura, who is one of the world's wealthiest men, arrives with his bodyguards in a $450,000 car. He wants to bring his irresponsible son back to Japan. Hiro has mysteriously vanished to the United States, and that is intolerable! He has a need for appropriate defenses because there are evil people in the world — people who will kidnap rich men, or their children, and hold them for ransom. My character is very old school and believes in learning the business from the bottom up. He was brought up that way by his father, and he wants his son raised that way, too. That is why, when the series began, you first saw Hiro working in a cubicle. The Nakamuras are members of a long and very important Japanese dynasty. In ancient times we were in the shogun class. An old powerful family of the Japanese aristocracy would certainly have family treasures, and that could include a sword.... Only samurai were allowed to carry swords, and the upper echelon had the best of the swords, so therefore they became heirlooms.
