By this time, the Japanese 7" singles began to mimic the UK releases by dropping the loose picture inserts/Toshiba EMI sleeves in favour of full picture sleeves. The Japanese writing on the front of these sleeves started to get smaller and less bold as well.
This release does come with an additional paper insert. A black and white photo of Kate is featured on the front and on the reverse are the lyrics to Babooshka and Ran Tan Waltz in both English and Japanese. There is some additional Japanese text on the back, but I have no idea what any of it says. I'm presuming it's information about the album Never For Ever as it shows a small photo of it here.
You might spot how some of the lyrics to Ran Tan Waltz are terribly incorrect. This seems to be a common trait with these inserts.
