No more free Cool Extras for Japanese text?

Previous versions of Illustrator came with a  "Cool Extras" folder, containing items such as a folder full of "How Did They Do That!", Charts and Graph examples, and a series of pre-made templates, for common designs such as banners, DVD screens, business cards, and a host of Japanese designs highlighting details of Japanese typesetting with Illustrator.

However, I did not find any such "Cool Extras" in CC 2018, and looking back into my previous installation -- CC 2015 -- it seems these are not there too. The "Cool Extras" folder contains a rather bland selection of 15 common designs.

Where and how do I get a CC 2018 version of these templates? Am I supposed to

1. "must have" an older Illustrator version to copy them from (also inferring that there was 'nothing new to add')? and/or

2. set my CC global language preference to Japanese -- hoping that this does not set all menus, selections, and dialogs to Japanese as well? Which, I am convinced, would quite be the purpose of that setting, so I am unwilling to go ahead and try it... and if I am correct it would install a separate CJK version of Illustrator, with all of its menus etc. in Japanese.
