Deletion of Kikuo Harigaya

Comment: I did some work on this subject last night, but I didn't get the chance to post. Basically, the Science Citation Index lists nothing for Kikuo Harigaya. At first I wasn't surprised by that result considering the index looks for mostly English-language publications and their citations. However, I also checked Google Scholar. I found a few citations here and there and verification of his English-language publications. For me, it becomes a tough call because I don't want to be unfair to Dr. Harigaya's work and impact.  lists several notability criteria that don't seem to apply to Hiragaya. That leaves us with #1 and #4 -- ''The person's research has made significant impact in their scholarly discipline, broadly construed, as demonstrated by independent reliable sources'' and ''The person's academic work has made a significant impact in the area of higher education, affecting a substantial number of academic institutions''. Based on what we have, I'm leaning towards delete. I speak and read Japanese, but I'm not aware of a Japanese-language search engine similar to the Science Citation Index. For me, that index is probably what we should be consulting. If new information arises that he's significantly cited in the Japanese-language community, I'll change my opinion for sure
