Narita Luggage Storage in Terminal 3

I am living in Naha Okinawa, and will fly out of country from Narita Airport. For the week before, I would like to travel through Japan without my luggage. Two questions:

If I am flying from Naha (Okinawa) to Tokyo (narita) At the beginning of the week, is there a place to store my luggage in terminal 3? I will be flying into terminal 3 and leaving from terminal 3 the same day to go to osaka. If not, is it easier to travel to terminal 2 or terminal 1 to use their luggage service and return to terminal 3?

Another option I've heard of is Yamamoto luggage shipping from Naha to arrive at Narita for my flight one week later. Anyone know if this is possible from Naha?

Thanks!
