[wesman5060]

Hello! I recently purchased this Japanese "Good Luck Flag" at auction and although I have yet to receive it, I would like to try and start the process of translating it. I would be incredibly grateful for any help this forum could provide. Thanks yall!

It should be oriented so that the very large letters are on the right side. The vertical large letters are a dedication to Kenji Takakusagi (various possible readings of the last name), from Kojima Toyoshichi. The horizontal letters say "good luck in battle", which is a nearly universal saying found on such items. There are a few other patriotic slogans on the flag. The vast majority of the smaller writing are names, signatures of the people signing the flag.
