My imression is negative. It's too messy, and there is a critical misspelling of an okurigana "空ら明て" native Japanese would never do.
The main presenters are the president and vice-president of a neighborhood association of a town in Tsuru-machi Taishō-ku, Osaka, so the recipient would live there. His surname is indeed Shigeta, but I'm not certain of his given name.
If you have a larger/clearer picture, we might be able to read the red stamp.
He just wrote what he could read. It doesn't guarantee the authenticity at all. It's quite often the case that those typical patriotic slogans are written on fake flags.The individual who I’m buying it from claims to specialize in the region of Japanese items from that era Good Luck Signed Flag-0049 - FORTUNES OF WAR MILITARIA Specialists in Imperial Japanese Good Luck Flags, One-Thousand Stitch Belts, Banners, Amulets of Protection - FortunesOfWarMilitaria.com I am somewhat unsure if I want to even buy the flag now... any advice? Everything else on the flag seems to check out other than the location, but I’m still a little on the edge about it.

By th way, he misread a kanji in the stamp. The name of the village was Kishino, not Kishida. Kishida village didn't exist even in that era.

Also, he mistranslated the word 村役場 "mura yakuba". It's "village office", as I translated, not "village council". Village council is 村議会 "songikai" in Japanese.
Judging by everything you have told me I have decided to steer away from that specific Militaria dealer. I really appreciate all of the information you have provided me with. I have 2 more flags for you to look at if you do not mind from Griffin Militaria again, and these are a little bit different. What do you think of these?
