> Most Japanese Tweets are 15 characters while most English Tweets are 34

Doesn't the graph shows that most English tweets are 140 characters instead? The first peak on the English curve is indeed on 34 characters, but it's lower than the 140 peak.

You're right about the mode, but the quote is also correct in the sense of the area under the curve. Most English tweets are 34+/-n characters, where n gives you more than 50% under the curve. It rapidly falls off from 9% on the 140 character side.
