Bankrupt chip maker Elpida's shares delisted in Tokyo

Shares in Elpida, one of Japan's biggest computer chip makers, have been removed from the Tokyo Stock Exchange after its bankruptcy filing.

Elpida makes dynamic random access memory (DRAM) chips used in the manufacture of mobile phones and other personal electronic devices.

But it fell victim to tough competition from firms in South Korea and Taiwan as well as the strong Japanese yen.

Ryoji Musha from Musha Research in Tokyo told the BBC's Asia Business Report that the failure shows Japanese electronic manufacturers need to rethink their long term strategies for remaining competitive.
