I merged your two threads since you are asking about the same flag. There are plenty of names and typical patriotic slogans written on it. You can see those slogans in the following thread.

The recipient's given name seems to be 瑛新 "Eishin", but his full name isn't written on the flag. He would have something to do with Yamanashi Prefecture, judging from some dedicators' title 甲府警察署 Kōfu Police Office or 山梨縣廳（＝県庁）山林課 Forestry Division, Yamanashi Prefectural Government.
By the way, which is correct, you already have it or you are still planning on purchasing it?
