Leaving Tokyo for 1–2 years – how to move and store belongings locally?

I've been living in a Tokyo apartment for the last year (Asakusa/Kuramae area) and I have a unique challenge coming up: I'll need to return to the US for 1-2 years, before hopefully coming back to Japan. Now, my visa situation is fine, and my job situation is also fine.

My challenge is this: I need to find a nearby storage facility where my stuff can be kept, hopefully climate-controlled, for those 1-2 years. And, I need to find a mover who will pack up the stuff in my apartment (not that much stuff, but still), and move it to the storage facility.

What's worse, I need to do the above with only N5-level Japanese, so it would help if they spoke English. Any advice would be appreciated!
