Need Tranlastion Help- I Think He's Shouting In Japanese

The video is loud. I’ve had this alarm clock for years now. Since he’s a samurai, I assume it’s Japanese. If anybody could translate I’d be very greatful.

Samurai Alarm Clock - Album on Imgur

The link is completely work safe (though loud). It just wouldn’t let me embed the link normally.

Thanks

Until you get a better answer, a comment on the below youtube video says its “Wake up! Its time to fight the battle!”

I wasn’t expecting a stranger to comment on my IMGUR post. One did. And they really seem to know what they’re talking about “初陣じゃ! Uijinjya! 起きろ, 起きろ! Okiro, okiro! means Your first battle! Wake up, wake up! in Japanese FYI”

This thread remains open only because they said they were having troubl hearing the clock and may have misheard.

So not this?

Shouting Japanese
