Mitsubishi Electric Corporation, part of the large Japanese industrial conglomerate, have supplied a femtocell to NTT DoCoMo since July 2007.

A second generation product became available in September 2008, which uses the latest HSPA technology to achieve peak download data rates up to 14.4Mbit/s and upload to 5.7 Mbit/s. These rates are much more useful in the Japanese market, where fixed network broadband data rates are higher than those typically found in Europe.

The product is used by NTT DoCoMo in their "Home Area" product which targets poor coverage in the home.

There is little public information regarding this product, which appears to be marketed only to NTT DoCoMo at this stage. It is unclear if Mitsubishi are providing their own femto gateway, or if a 3rd party vendor is supplying this component.

NTT DoCoMo uses a slightly different variation of the global UMTS 3G standard, which they brand as FOMA. This operates at a slightly different frequency (1500MHz) and is not directly compatible with all standard 3G phones.

NTT DoCoMo publicly launched their "MyArea" femtocell service using this second generation femtocell in November 2009
