|With over 1000 episodes aired, Mito Komon is currently the longest running Japanese TV drama in history.|
The main character, Mito Mitsukuni, is based on Tokugawa Mitsukuni, one of Tokugawa Ieyasu's grandsons (son of Tokugawa Yorifusa) and lord of the province of Mito (now Ibaraki prefecture). Born in 1628, he was a scholarly recluse best known for researching the Dai-Nihonshi, a history of ancient Japan. Later in his life, he adopted the literary name "Komon" (Yellow Gate). The stories are based on popular legends about his incognito rovings around Ibaraki.
