Simply, Kyosho did not sell the Sensation in Japan.
Sensation is sold by Yoshioka. They also had larger 90 and 120 size Sensations. I am just not sure if Kyosho really produced both Sensation and Majestic. Kyosho already has more than enough number of pattern and 3D related ARF planes in Japan. It is either GP is just too selective or the Kyosho Japan does not want to sell all their arfs to US.
