As a historical figure born in the 18th century, he's not going to be easy to judge using  (no h-index for him!). But one strong indication that he is notable is how much he has appeared in published encyclopedias and dictionaries. https://kotobank.jp/word/%E8%8D%89%E5%A0%B4%E4%BD%A9%E5%B7%9D-16411 Here is his entry on Kotobank, which is a database of major Japanese encyclopedias run by the Asahi Shimbun, one of Japan's major newspapers. Here alone there are digested entries from six separate encyclopedias published by major publishing houses, including, I might add major word dictionaries (it is like him appearing in Webster's). http://ci.nii.ac.jp/search?q=%E8%8D%89%E5%A0%B4%E4%BD%A9%E5%B7%9D&range=0&count=20&sortorder=1&type=0 Here is a list of recent academic articles on him using the CiNii database (a government sponsored academic database that is not complete, by the way). I can't access those now, but it is clear he is a historical figure that is considered notable by other encyclopedias and the scholarly community in Japan
