In '87 NTT made it first public stock offering and demand was so high there was a lottery to buy (yes). Within a few months the price dropped by half. Then in '90 came the recruit scandal [ latimes+com / archives / la-xpm-1990-10-09-fi-2322-story+html ]. Part of it was an 80 yr old NTT exec received unlisted shared in a company 'Recruit' before official listing and price rise, and NTT reciprocated with cheap land lines. The exec was fined $175,000, which was only equal to his illegal gain, and a suspended sentence.
