Japanland: A Year in Search of Wa is a 2004 documentary television series (broadcast in late 2005) and book by American documentary filmmaker and travel author Karin Muller, who spent a year in Japan searching for wa, the Japanese concept of harmony (it is also the oldest recorded name of Japan). Japanland was written and filmed by Muller, an American judoka who traveled to Japan in 2001 to improve her art and realized she could not succeed without understanding Japan itself, so she set out on a one-year solo trip around Japan to see what she could.
