My google results do no match yours. Mainichi has a story and does not include that quote (or any other). Nikkei as well. There is a Youtube video of the story which describes it, but includes no quotes. It mentions that there is an exhibition where you can go and see the artefacts. I could not find the story in the Japanese version of the Yomiuri newspaper from google, but I found another site that linked to it. When I followed the link, it was dead. The focus of the articles I've read seems to be that this is the oldest written evidence of Persians coming to Japan, which I agree is very interesting.
