Naha sightseeing bus

I'm looking for how to sightseeing in Naha 1 day and I see Yui Yui loop bus. It's an answer for me. But I wonder if it still transports on late of December 2014...I notice that Yui Yui loop bus is limited to August. What year? And next question is what is its terminal no.at Naha bus terminal? Thank you.

The Yuiyui bus runs throughout the year and leaves from stop 12 at Naha Bus terminal.

Bear in mind that this is not really a sightseeing bus with guide, rather it a regular bus which stops at the most popular sightseeing spots within Naha where you would sightsee on your own.

Thank you very much ^^
