DW3000 Japan certification?

Has the DW3000 been submitted for certification for use in Japan?
Is there a TCM cert# for it yet?
When do you expect they might become available?

Is it normal in Japan for radio ICs to get certification?

The DW1000 doesn’t have FCC/CE certification. As far as I know only the DWM1001C when running the PANS firmware has certification. For any other configuration you need to get your own certification.
