Many travel shows are about food. The new TV Tokyo series, "Gakuryu Shiraberu Toraberu" (Reverse Current Investigation Travel; Mon., 8 p.m.) takes the idea one step further.

Every week the show chooses a common foodstuff and traces it back to where it came. Since Japan's self-sufficiency rate for food is only about 40 percent, the program will never have a shortage of subjects.

This week's is octopus, much of which is imported from Morocco. The video crew travels to the coast of Morocco where they meet a "legendary octopus fisherman," whose technique is said to be very special. Along the way, they discover the "astonishing variety" of Moroccan cuisine and visit a village that has been designated a World Cultural Asset by the U.N.
