Tips for Curly hair in Japan?

Hi! I'm studying abroad and just got to Japan two days ago, and the humidity is driving my hair crazy. I have curly hair 2c/3a and was wondering whether someone has any recommendations? I brought some products from back home but I doubt they will last me very long… I usually just shampoo & have a conditioner that i use like a mask in the shower, then follow with some mousse and crunch out curl cream. I've read that &honey oil is good, but not sure when to apply it. My hair is thin so any super heavy products weigh it down… I also couldn't fit my diffuser into my luggage anymore so if anyone has any good recs for a diffuser/hair dryer that I can buy locally, it'd be appreciated! (though i highly doubt they have diffusers here).
