Here's the link to the website: http://www.honda.co.jp/CLARITYPHEV/ (in Japanese, of course) Working through Google Translate, I can't make out everything. However, I found several notable differences so far: There appears to be a CHAdeMO fast charging port on the driver's side (right in Japan) rear. It also includes a level 2 port in the PHEV's standard position (front left). Not surprising since CHAdeMO is very common in Japan for public charging. Cobalt Blue Pearl seems to be an available PHEV color in Japan, unlike in the U.S. (alas). The other color options seem to be the same as the U.S. It looks like the fuel cell model's air filtration system is included. The FCV's traffic sign recognition feature seems to be included too. There only seems to be one trim level, equivalent to Touring, but there's no Touring badge. Android Auto isn't advertised as a feature, but Apple CarPlay is. Maybe Android isn't big in Japan? The infotainment system appears to be the same knobless design as on all previous models, and the Honda Sensing features appear to be the same as the U.S. model (except the sign recognition). No sign of the FCV's HUD. Let the tea leaf reading for what this portends for a hypothetical North American 2019 model begin.
