Things that I want to do:
BioPark (on a Saturday or Sunday)
Nagasaki Atomic Bomb Memorial Museum
Hiroshima Atomic Bomb Peace Museum
There are a few links for Hashima to check out:
Make sure to check what times the vessels will be out and come back if you are doing more than one thing that day.
Now, I know I want to go to BioPark on the way back to Fukuoka, so that trip is taken care of.
I was thinking doing Nagasaki on one day and then Hiroshima another day.
If we hit up Hiroshima, we can spend the day there to see the Museum and the temple and then head back to HQ
3 h 28 min
In current traffic: 3 h 33 min
So, hit up Hashima in the morning and then go to the museum after (8:30 to 18:30 hours of operation)
Actually, now that I'm thinking about it, it would make more sense to go to Nagasaki first THEN Hiroshima. We are planning on making our way down to Osaka after that so it making our way more NE would be better.
