Fukuoka Green Pass

hi I read about a green pass which I can buy which gives me unlimited bus access from airport to a few tourist spots in Hakata City.

May I ask 1) where to buy Green Pass from Fukuoka Airport? 2)where can I find a English map to see the bus routes of Green Pass holders? 3) whether Green Pass can be used for all days of the week? 4) is it valid only for one calendar date, or is it for 24 hour range from the time you buy the pass?

"I read" where?

Yes I read about it on this website. Unfortunately the attached flyer is in Japanese, and I can't quite make out the route.

It says it can be used for travel to/from airport but doesn't say where to purchase it.

It might very well be that you don't need the Green Pass. Many good places to see are near a subway station, and the subway goes all the way to the airport.
You can get a subway day pass for 620 yen on a weekday and 520 yen on a weekend.

Be aware that the passes for the buses don't cover the entire city - but they do cover the areas that most people would like to travel to.
One other place you should include is the Nanzoin Temple - about 20 minutes by train from Hakata Stn. One of the best places in the country, and nearly unknown to the outside world.

There's a 1 Day Fukuoka Tourist City Pass for 820 yen or 1,340 yen (incl Dazaifu)

thank you for the replies. I have decided to buy the subway pass instead.
