Forum:Strange 1985 PC8801 port of Ultima III

I recently came across this strange 1985 PC8801 port of Ultima III, in which the company Thinking Rabbit was credited with the conversion.

This is not the PC8801 version that was included with the original Japanese version of the Ultima Collection, which was produced in 1989.

I can't find much about Thinking Rabbit, other than that they were a Japanese software company during the early 1980s. Any idea what the deal is with this port? Was this an actual release of Ultima III that was retailed in Japan 4 years before the PC8801 release?
