My senior daughter told me that she couldn't watch "The movie Crayon Shin-chan The Great Battle in Warring States period" is not available on Amazon Prime.
Maybe she want to have a screening at a friend's house, I think.
But, well, what can I say -- I did something about it (details omitted).

Together with "Crayon Shin-chan The Adult Empire Strikes Back in heavy storm", these two movies are the best of Japanese movies (not "Japanese animation movies").
As a father, I am willing to help her for her activity.

People who know about these two works naturally know about them, and people who don't know about them naturally don't know about them -- it cannot be helped, however,
I think it's better to watch them without prejudice.
I won't let you regret it.
