TOKYO -- The Tokyo Stock Exchange, the backbone of Japan's stock market, experienced a system failure on Thursday. This is the third time that the exchange's "arrowhead" trading system, designed and developed by information technology services company Fujitsu, has experienced a critical failure.
Previous failures occurred in 2005 and 2012. Fujitsu had been generating good business results as it pursued its own digital transformation, but the most recent mishap could undermine its credibility and stall its progress.
