June 3 through 10 is Eco Week on Nippon TV, so it is airing some specials emphasizing environmental issues. One is "Chotaiken! Time Warp Ryokosha Oedo-hen" ("Super Experience! Time Warp Travel Agency Oedo Edition"; Tues., 9 p.m.).
The Time Warp Travel Agency sends customers on journeys back in time. A family of four is transported to old Edo, the capital before it became Tokyo, when the citizens had to use their imagination to get by. It was a simpler, more environmentally friendly era.
The father becomes a sushi chef and the mother learns to appreciate fresh food that isn't processed. The kids find out how people lived in nagaya (traditional townhouses), and everyone discovers the wisdom of surviving with less.
