Christmas reading suggestion

The Japan Times has a short article on a new book entitled: "Suisen Toire wa Kodai ni mo Atta — Toire Kokogaku Nyumon" ("Flush Toilets Existed in Ancient Times — An Introduction to Toilet Archaeology").

The author "was first captivated by toilet archaeology when he excavated the late seventh century toilet remains at the Fujiwara Palace in Kashihara, Nara Prefecture, in 1992.."

Not quite Indiana Jones, but it's a living.
