Those particular channels only seem to broadcast from satellite within Japan, between the Japanese satellites 110E, 124E and 144E. Unfortunately the footprints for these satellites are quite tightly focused over Japan, which means that reception of these within the US would be virtually impossible, at least without living on the extreme west and have a humongous dish handy.
The only satellite operater in the US that I'm aware of that offers Japanese TV is the Dish Network. They offer one channel called 'TV Japan' which consists of Japanese language programming. The channel is also free-to-air on 129W, however as transponder is on C-band, you will need a C-band dish and compatible digital receiver to pick up this channel.
It may be worth asking any cable operators in your area to see if they carry any Japanese TV. However, when it comes to satellite it looks like there is very little choice that I can come across.
