Okunoshima route

Hi,

Trying to figure out the most ideal route to Okunoshima.

Osaka - Okunoshima - Hiroshima or
Osaka - Hiroshima then Okunoshima the next day

The route seems long from Shin Osaka.

Thank you all in advance

Rabbits on Okunoshima have halved in the last three years.

I've never been there, so I don't know for sure, but if you go when the sun sets early, you might not be able to see it because the lights aren't on.

In that case, it may be easier to see the rabbits in the early hours.
Rabbits are most active in the morning and evening.
