His name was revealed as "Arai" only, so the page "Arai" was created. Then after time his first name was revealed and the page was moved from Arai to Hirokazu Arai. I left the redirect as it was till helfpul.

Like if I want to link to his page by: it will recommend me the page "Hirokazu Arai" because "Arai" redirects to it. Without Arai redirect it would not suggest Hirokazu Arai. Like if I write it will not suggest Kobeni Higashiyama, as there is no page starting with Higashiyama. Same thing is true when you use the search. If you write Arai in the search box it will suggest "Hirokazu Arai", but if you write Higashiyama it will not suggest "Kobeni Higashiyama". And considering that Arai is mostly known by that name and not as Hirokazu, most people will search Arai, so having that redirect will be helpful. Naturally if you hit enter while typing "Higashiyama" it will still find Kobeni Higashiyama, but won't suggest it while you are typing it.
