Does anyone know where to buy these from?? I heard that they are a tad bit smaller that the us batteries and was hoping to scoop one up.

 

Batteries come in Group size.theres no specific battery for each car for the most part.find out what size (if they even classify them in group size in japan)and purchase that size which i doubt is different from usdm.

 

I would save the trouble and pick up a mini battery.
