Kyushu 8D Trip Dec

Hello,
I am planning for a family trip to Kyushu for 8 Days. Will be getting the 5 Days All Kyushu pass Need advice as to how I should plan (to start from and last stop before hearing back to Fukuoka) and time needed for each of these places of interests we would like to visit:

We would also like to know based on your proposed route, where should we spend the night at and any suggested ryokan/hotel?

Currently, our plan is to spend one night in Beppu and one night in Ibusuki.

1. Huis Ten Bosch - Dutch town
2. Tosu Outlet
3. Beppu - Hells (blood pool)
4. Mt. Aso - crater
5. Yufuin - what is interesting to visit?
6. Kumammoto - Castle
7. Kagoshima - Ibusuki

Pls share any information you may have. Thank you.

1. Huis Ten Bosch - Dutch town
The monuments in Nagasaki are other things possible.
For the Christians who were martyred and those who suffered or died due to August 1946.

2. Tosu Outlet
No idea what this is

3. Beppu - Hells (blood pool)
Not just seeing but hopping to the many hot springs

4. Mt. Aso - crater
The drive from Kumamoto to aso is scenic. Train ride is nice too. On the way the train will slow above a valley. The bridge is the first train bridge in Japan. It's red.

5. Yufuin - what is interesting to visit?
Nothing much
It's just a place to seriously relax
Just stroll round town
Eat local delicacies
Enjoy onsen bath
Yufuin burger is popular

6. Kumammoto - Castle
And the garden too
It's a bustling city that's just nice to walk about and eat at. But other cities like Osaka/Nagoya gives such a feel too.

7. Kagoshima - Ibusuki
Sakurajima to learn above volcanic ash, lava, and history of the volcano.
Ibusuki for the sand bath and food. It's resort town. Just relax. Flower gardens might not be that interesting since it is past summer. But a local night know better.

I think it makes sense, if going by train, to go by Fukuoka Nagasaki
Nagasaki Kagoshima&ibusuki
Kagoshima Kumamoto
Kumamoto aso
Aso yufuin&beppu

If there's more time you could pop by Miyazaki. Takachiho udojinja
Or from Kagoshima go to yakushima or tanegashima
But your train pass is only for 5 days so its up to you how much you wanna spend
