Hot and sweaty

So I recently moved to Osaka about four weeks ago and as you know it’s been hot and humid as of recently. I’m originally from GA in the U.S and grew up in AL, so I thought I knew heat. I don’t think I’ve sweat this much in my life. I’m not dressing heavy either, I step out of my apartment to go to the grocery store that’s not even a block away and my pits? Just drenched. I know that deodorant isn’t as common like back in the states here, but has anyone else experience this or tried products that work?

I’m not sure if my body is still trying to regulate for the change in climate or if it’s really just that hot, or if it’s just me lol.

Thanks!
