Two big Japanese electronics companies, namely Hitachi and Mitsubishi, are to stop producing parts of their product portfolio domestically: Hitachi announced [JP] it will end production of plasma and LCD TVs in Japan, marketed under the Wooo brand, by September this year.

The company owns a plant in Gifu prefecture in central Japan that churns out about 100,000 TVs per month (pictured: a Hitachi Wooo plasma from 2009). Citing price competition in the TV business as the main reason for the move, Hitachi said the plant will be used to produce projectors and chips instead.

The company will continue to offer Wooo TVs made by non-Japanese contractors.

On the same day as the Hitachi announcement, Japanese newspaper Asahi Shimbun is reporting that Mitsubishi has decided to stop the domestic production of DVDs and Blu-ray discs.

According to the report, the main reasons for the decision are declining DVD sales and (still) weak Blu-ray sales. The company has been producing these discs in its own plants in Singapore and Okayama prefecture in Western Japan for years. Now Mitsubishi is planning to outsource optical disc production to partner companies in India and Taiwan in the future.
