I just ask this question out of curiosity.

I would like to hear opinions from researchers in Japan about this paper:
Speciation of two gobioid species, Pterogobius elapoides and Pterogobius zonoleucus revealed by multi-locus nuclear and mitochondrial DNA analyses

The first author is Akihito, unless there is another person with that single unique name at that unique address.

Did he really contribute anything to that paper? Note that he doesn't have any degree, and he was 82 years old when that paper was published.

Updated:

I'm asking this question because the author is an emperor, i.e. somebody with immense power.

An author with similar level of power was Elena Ceausescu. She only finished primary school. However, during the communist period, thanks to her dictator husband, she had a PhD, countless of papers and awards etc etc.

That's why I'm asking people in Japan. I do know how to use Google.
