FACTBOX-Jail-terms and arrests in Japan's top corporate scandals

(Reuters) - Tokyo District Court sentenced 34-year old Internet entrepreneur Takafumi Horie to 2- years in jail on Friday for his role in a securities fraud at his former company Livedoor, a rare jail sentence for a top executive.

Here are some other high-profile cases where corporate dealings in Japan have led to the law courts or high-profile falls from grace.

MILITARY SECRETS SCANDAL:

- Three Yamaha Motor Co. officials were arrested in February this year on suspicion of exporting small crop-spraying helicopters to China without government permission.

- Police believe Yamaha, which has denied any wrongdoing, exported seven or eight of the unmanned helicopters to an aerial photography company in Beijing called BVE in December 2005, aware of the possibility that they could be modified for military uses.

SHAREHOLDER ACTIVIST'S INSIDER TRADING:

- Financier Yoshiaki Murakami, whose demands that companies cede more power and profits to shareholders terrified corporate executives, was arrested on insider trading charges last June.

- Pleading not guilty at the start of his trial in November 2006, the 47-year-old former trade bureaucrat faces up to three years in prison or a fine of up to 3 million yen ($26,000).
