Learning Japanese without a Kanji (for a moment)

I know that Kanji is integral in Japanese. I'm currently working on better reading of hiragana and learning katakana (for some reason its harder than hiragana).

In few months i'm going to Japan and i realized i'm gonna end up in some parts where i probably will need to talk Japanese and I suck at learning Kanji and must work on it slowly.

I want to know if there are sources or way to learn more communicative japanese without depending on kanji. I want to separate that as i learn, because Kanji would just break any progress for me.

I know generally, if i would want to have certificate i have to learn Kanji, but for the talking i think it should be okay to separate it. Please help me.

Edit: Thank you everyone.
