Found: 1960s Children's novel girls ?sisters visiting Japan

A fairly short chaptered novel read to a UK class of 8/9 year olds around 1969/1970. Featured 2 girls, possibly sisters, visiting not living Japan I think. Mentioned tea ceremony and kimono descriptions. Also described paper sliding screens and they may have been pictured on the cover.

Maybe The Bobbsey Twins and the Goldfish Mystery?

Thankyou but definitely not that book. That wasn't a book series we used and although what I remember was a novel it was more information/realistic based and possibly aimed at a higher age group.
Sorry for so little detail, it was a long time ago!

Books from the right period in Worldcat, these all look to feature a brother and sister though:

Visit With Us In Japan 96 pages, a US publication

Ann and Peter in Japan, part of a series called "The Kennedys Abroad"

Our Japanese Playmates

Thanks for the suggestions but still not the book I'm thinking of yet.

Found! By chance I heard the title mentioned on BBC radio 4 and have just listened to a dramatisation. I had the gist but it wasn't sisters in Japan it was about 2 cousins and one of them makes a Japanese doll house and the story is told partly by the 2 dolls, describing their house, the paper screens, tea ceremony etc. I remembered as soon as I heard the title - Miss Happiness and Miss Flower by Rumer Godden 1961.

Touchstone: Miss Happiness and Miss Flower

Oh, please read the sequel, Little Plum, too.

Thankyou, I will.
