Japan’s Nikkei 225 share benchmark surged Thursday to an all-time high, bypassing its previous record set in December 1989 on heavy buying by global investors. The Nikkei 225's previous record was 38,915.87, set just before Japan’s bubble economy collapsed in the early 1990s. Japanese shares have logged sharp gains in recent months, helped by strong interest from foreign investors who account for the majority of trading volume on the Tokyo exchange.
