TOKYO -- High-tech shares such as industrial automation company Keyence were behind a 20% gain in the total market capitalization of shares listed on the Tokyo Stock Exchange's first section during 2017, but businesses mired in scandals did not come along for the ride.
The total value of the TSE's first section stood at 683 trillion yen ($6.06 trillion) as of Friday, climbing by 112 trillion yen this year. This increase was propelled by a stock market rally, with the Nikkei Stock Average hitting a 26-year high in November.
