The Nikkei 225 Index fell 1% to below 64,600 on Thursday, while the broader Topix Index declined 0.65% to 4,020, extending losses for a third straight session. Elevated oil prices intensified inflation concerns and raised expectations for near-term interest-rate increases. Japanese shares also followed overnight losses on Wall Street after US Treasury yields surged when the Treasury Department announced plans to buy back up to $6 billion in longer-term debt, below what some investors had anticipated. The yen strengthened to a near seven-month high, while technology and consumer stocks led declines, including Fujikura, Ibiden Co, Furukawa Electric, Nintendo and Fast Retailing.
