The dollar has reached the mark of 86 yen by the begining of August 2010. Japanese analysts see the dollar at 90-100 yen as reasonable for Japan's export based companies. One factor causing this is the Chinese government increasing its holding of Japanese government bonds. By May 2010 China had accumulated 1.27 trillion yen according to the Japanese government. This rise of the yen will have a negative effect on Japanese exporting companies.
