Japan support for TomTom Map?

So far I am happy with the result for TomTom Map and I live in Hong Kong, it seems like most functions are pretty good but it seems like I cannot get any result for Japan. Honestly the focus of my application mainly relies on structuredGeocode and reverseGeocode but it struggles to find anything in Japan. Mind if I ask if Japan is a country that will be supported in the roadmap or it is not planned for TomTom map to handle that?
