Thank you,

You are missing Aizu!

Hitachi seaside park in ibaraki

three days Nikko is a day too much...I think
Aizu is really beautiful :)

Thank you for suggesting Aizu! It looks very interesting.

I see it is connected to Nikko via direct local railways. Travel times are a bit long and trains are not very frequent, but it is definitely doable with proper planning.

I'll give it a try!
