TOKYO: Japan's financial institutions must guard against cyber-attacks ahead of the 2020 Tokyo Olympic Games, with nearly 40% of banks and other firms experiencing attacks over the past three years, the Bank of Japan said on Jan 31.

The increasing threat of cyber-attacks has prodded the Bank of England and other central banks to take action to ensure that banks, insurers and other financial firms minimise the impact of cyber-attacks or technology outages.
