BANK OF JAPAN INTERVENES SOON AFTER TOKYO OPENING The Bank of Japan bought a small amount of dollars shortly after the opening at around 145.30 yen, dealers said. The central bank intervened as a medium-sized trading house sold dollars, putting pressure on the U.S. Currency, they said. The dollar was also supported by a major electrical consumer goods company, which was a speculative dollar buyer at around 145.25 yen, they added. The dollar opened at 145.33 yen against 145.60/70 in New York and 145.25 at the close here yesterday.
