Bus to Rakanji Temple

Hi,
I plan to go to Rakanji Temple in Nakatsu(Oita) next January 2013. I have to take a Daikouhokubu bus from the Nakatsu station. How often the bus operate? Do you have a bus schedule?

The temple seems to be a 20 minute walk from Nakashima bus stop, which is a 30 minute ride from Nakatsu Station by a bus in direction of the Yabakei. There is about one departure per hour. Departure times from Nakatsu Station are listed in the rightmost of the three columns on the following page:

(i.e. 7:30, 8:30, 9:40, etc.)

Departures from Nakashima in direction of Nakatsu Station are here:

The temple's official website also suggests using the "Yabakei Meguri" sightseeing bus that operates once per day on Sundays only and visits also other local spots besides Rakanji:
