Help dating a silk kimono style robe

[Eliezer Vintage]

Hi everyone! I recently found this absolutely gorgeous silk kimono style robe, fully lined. I’m having trouble dating it if anyone can give me some insight. I know Hayashi is a store in Tokyo that has been in business since the 50s that sold kimonos and robes to tourists but I’d love to nail down a decade. What would you date this as? Thanks!

The slit on the sides is unusual, I wonder if it may originally have had pants to go with it.
I am seeing 1960s. Let's see what others think.

I'm seeing a tourist buy/souvenir, 2000 or there about.

Interesting responses and I’d love to hear more! My bet was 60s as well so I’m surprised by the c. 2000. Hopefully others can weigh in as well!
