In this week's episode of Japan's longest-running historical drama series, "Mito Komon" (TBS, Mon., 8 p.m.), about an itinerant nobleman who travels the land incognito righting wrongs, the white-haired hero and his retinue enter the town of Hamamatsu and encounter the procession of the Lord of Tsuyamaon, which is on its way back from Edo to present-day Okayama Prefecture. Though Mito is a nobleman himself, he bows to the entourage since he is in disguise.

Shinkichi, one of Mito's followers, is anxious to arrive in Hamamatsu because he has heard that his mother, whom he hasn't seen since he was a child, lives there. At the same time, the Tsuyama procession decides to spend the night in the town, and one of the retainers tries to poison the lord's son. He is saved by Shinkichi, but his life is still in danger.

On Tuesday, NHK starts a five-part drama called "Rikon Dokyo" (Divorce Cohabitation; NHK-G, 10 p.m.), about an unsuccessful photographer named Masaru (Sadao Abe) who has an affair with a young model, Ami (Ryoko Kobayashi). His wife of eight years, Noriko (Eriko Sato), finds out and demands a divorce, which Masaru grants reluctantly. Noriko leaves with their young daughter.
