The Japanese version of Super Troll Islands shares the core platforming and exploration gameplay of its international counterparts. However, regional differences in graphics, level design, or even storyline elements are possible.  Further research is needed to identify the specific developers and publishers involved in the Japanese release, as well as to uncover any region-exclusive content.
