Stuck in Fukuoka - recommendations

My flight to Yakushima was canceled and I'm stuck in Fukuoka. Going to Yakushima next is no longer an option. I have 2 days before I need to be in Ibusuki after which I will hit Nagasaki and then Karatsu before flying out of Fukuoka. Any recommendations of what to do between Fukuoka and Ibusuki? I like hiking, temples, food, and onsens.

Definitely Dazaifu. Specially the temple right close to the shrine (which is also nice). I could spend a long time just gazing into their zen garden. Plus you have a large and very interesting museum. Easy to reach from Fukuoka.

Dazaifu could easily fill up a day.

For the second day I did enjoy Yoshinogari historical park by Saga: http://bicycletraveljapan.blogspot.com/2017/11/day-53-yanagawa-to-saga...

But that might be harder to reach.

Enjoy your time in Kyushu!

Dazaifu is a good option. My post is not that good because there is one day of the week when the main museum is closed (along with the main temple that day I visited): https://www.japan-guide.com/community/mfedley/report-2680

Another few options include:

Nokonoshima Island: https://www.japan-guide.com/community/mfedley/report-2677

Karatsu: https://www.japan-guide.com/community/mfedley/report-2688

Yanagawa: https://www.japan-guide.com/community/mfedley/report-2676

Kokura: https://www.japan-guide.com/community/mfedley/report-2684

Thank you both. I just finished a 1/2 day visit to Dazaifu and am on my way to spend a couple of hours at Yoshinogari Historical Park (I hope).

Kagoshima City and Sakurajima are on your way to Ibusuki.

Just 20 minutes by train from Hakata Station in Fukuoka is the Nanzoin Temple - one of Japan's very best yet nearly unknown to most. Very worthwhile.

Kumamoto has a number of good places, especially around Mt Aso. If you rent a car, there are many more great places besides the volcano - Kikuchi Gorge, the Daikanbo Lookout, Nabegadaki Falls, the Yamabuki Suigen springhead, and many more.

On your way to Nagasaki, don't miss the chance to stop by the Yutoku Inari Shrine - it really is one of the jewels of the island - and almost always uncrowded.
