You shouldn't have to read Japanese, just need a strong magnifying glass to look at the head of the jet...should be able to see the numbers for their sizes 110/120, etc.! 120's are 4 sizes richer than 110's, and if your plugs looked good with the 110s, then you could have problems with the 120's, and could have fun tuning ie, raising floats and/or moving slide needle a notch higher, both to lean it a little!?

However, the bikes were jetted a bit lean in the later years for the EPA, and allegedly some were set up with staggered 110/120/120/110's! YMMV.
