David’s contribution gave me an idea for this post.
These pictures were taken in Gyōda、Saitama, Japan.
On the ground , we could see many lines in rice fields.
There is a tower near the rice fields.
From the top of the tower, we could see this pattern, a nymph with lotus flowers.
Sorry, my poor English ability 
I had hoped to visit there last year, but it didn’t work out. I forgot about it this year! Is it still open for viewing? Thank you
You’re welcome.
Yes, it is. I took this picture, last Saturday.
Thank you for your comment.
