This has been an exciting couple of months for Google fans in Japan. First the Nexus 10 launches, then the 3G Nexus 7, and now finally the Nexus 4. The Japanese product page is up, giving a rundown of everything Google's latest flagship phone has to offer. The hardware looks identical to the U.S. version, pentaband HSPA+ radio and all. The current shipping time is 1-2 weeks, and both the 8 GB model and 16 GB model are currently available.
