First of all, I'm very glad at your visit to my website, 66.7‰.
All pages on this website are written in Japanese only, so maybe it's a little hard for non-native people to read and understand pages.
However I greatly hope that all visitors including from overseas enjoy my website.
Today, in Japan, night trains which run every day are only Sunrise SETO and Sunrise IZUMO.
They have only compartment accommodations, therefore have no open-types like the picture you attached (Nobi Nobi Zaseki is not regarded as berths).
I wish that a revival of night trains come true someday.
