So far, Japan has not won any the 2006 Nobel prizes yet. See the official website at nobelprize.org.

Much worse is unlike previous years, Japan has not won any the IgNobles for zaney research. In most the past years, Japanese have won an IgNoble such as the 2005 prize for NUTRITION to the wacky fraud, Dr. Yoshiro Nakamats, of Tokyo (pictured grinning with his prize) who took a photo and analysed every one of his meal for 35 years (including poops) or the 2004 Ig Nobel PEACE prize to Daisuke Inoue for inventing karaoke. See the: “ig-Nobel past winners.”
This year’s 2006 IG NOBEL PRIZE for MEDICINE went to Francis M. Fesmire of the University of Tennessee College of Medicine, for his medical case report “Termination of Intractable Hiccups with Digital Rectal Massage”; and Majed Odeh, Harry Bassan, and Arie Oliven of Bnai Zion Medical Center, Haifa, Israel, for their subsequent medical case report also titled “Termination of Intractable Hiccups with Digital Rectal Massage.”
