Mori Hamada & Matsumoto and Davis Polk & Wardwell have advised government-backed fund Japan Investment Corp on its 909.3 billion yen ($6.4 billion) acquisition of semiconductor materials maker JSR, which was represented by Anderson Mori & Tomotsune.

This is the latest of the series of moves by the Japanese government to try and regain the country's lead in advanced chip production and maintain its edge as a maker of materials and tools used in their manufacture, Reuters reported.

The MHM team was led by partner Takayuki Kihira and included partners Hideki Ben, Norimitsu Mori, Yusuke Takamiya, Yuki Matsuda and Takeshi Fukuda.

Partner Ken Lebrun led the Davis Polk team, while the AMT team was led by partner Keiko Kaneko.
