TOKYO, Nov 28 (Reuters) - Japan's Toray Industries said on Tuesday it will hold a news conference regarding data falsification at a subsidiary, in what could be the latest in a series of quality-assurance scandals to hit Japanese manufacturers.

The major Japanese materials maker's president, Akihiro Nikkaku, and the chief of automotive tire-related materials unit Toray Hybrid Cord Inc will attend the presser at 10:30 a.m. (0130 GMT).

The announcement follows a spate of compliance failings at Japanese manufacturers including Kobe Steel Ltd, Nissan Motor Co Ltd, Subaru Co Ltd and Mitsubishi Materials Corp.

Shares of Toray plunged more than 8 percent following the announcement.
