"Anderson M?ri & Tomotsune is one of the ""Big Four"" law firms in Japan. The firm was founded in 1952 as O'Gorman, Nattier & Anderson after its three initial partners who were all American attorneys. The firm merged with Shenoh & M?ri in 1961 to form Anderson, Nattier, M?ri & Rabinowitz, which was renamed to Anderson M?ri & Rabinowitz in 1963. The firm changed its name to Anderson & M?ri in 1991 following the departure of partner Richard Rabinowitz, who joined several other Anderson Mori attorneys to form the firm of T?zai S?g? in 1994."
