Ok, here's some more information. I'm running Pandoc 2.7.3 on macOS 10.14.6.
---
lang: ja
title:
- type: main
text: "Wow a book"
creator:
- role: author
text: "Me"
language: ja
identifier:
- scheme: DOI
text: doi:10.234234.234/33
ibooks:
version: 1.3.4
page-progression-direction: ltr
---
And I am using the command:
/usr/local/bin/pandoc mybook_epub_apple_4pandoc /Users/me/Library/MobileDocuments/com~apple~CloudDocs/book-variables.yaml -o mybook.epub --from=markdown-smart --to=epub-smart --toc --toc-depth=3 --epub-chapter-level=2 -M date=2019-10-31 --css epub.css --resource-path .:/Users/me/Library/MobileDocuments/com~apple~CloudDocs/audio --epub-cover-image=cover.jpg --template mytemplate.epub3 &> epub_apple_pandoc_errors.txt
With this setup, cover.xhtml and title_page.xhtml have the language set on the HTML tag, but none of the chapter files do. (ch001.xhtml, etc.)

I just tried to generate an epub (something I don't usually do) having
set the `lang` variable to `sv` and as far as I can see every .xhtml
file in the archive has an attribute `xml:lang="sv"`, and the default
templates for both epub3 and epub2 have an `$if(lang)$
xml:lang="$lang$"$endif$` in the `html` tag. So one or both of the
following must be the case:
- Your version of pandoc is outdated.
- You are using a custom template which lacks the `$if(lang)$
xml:lang="$lang$"$endif$` in the `html` tag.
I suggest upgrading pandoc and/or adding the needed bit to you template.
