Awesome.
In addition to the obvious automatic transmission and tech package, the Japanese site shows there's a new interior light kit option. All previous NISMO extras, like the illuminated kick plates and premium floor mats, are also carried over.
***EDIT***
On a side note:
I just noticed from these pics, that the Japanese version has different seats. I should investigate that a little more. Seats are from a non-NISMO model (the silver isn't blackened). The light kit is offered for the entire 2015 line-up.
