A 66-year-old man involved in defrauding rock star Eikichi Yazawa out of 27 million Australian dollars (1.9 billion yen) was imprisoned for one year by the Brisbane District Court on Thursday, court officials said.

Harunobu Fukusato, from Saitama Prefecture, pleaded guilty to five charges, including forgery, dishonesty and failing in his duties as a company executive, a court registrar said.

The charges relate to the loss of Yazawa's money in the late 1980s and early 1990s in a coverup of failed property investments.

Yazawa's former agent, Hiromi Kawada, of the Island of Capri on Australia's Gold Coast, will be sentenced in March for his involvement, the registrar said.

Fukusato received a four-year sentence, to be suspended after 12 months, and was ordered to pay a good-behavior bond of A$500, he said.

Yazawa told a committal hearing in 1999 at the Southport Magistrates Court he did not know the two men were listed as directors of two firms in which the singer was the principal shareholder. Kawada and Fukusato forged up to 3,000 documents as part of a scam to defraud Yazawa of his money.
