It’s almost two years since Amazon allowed mainstream publishers to upload ebooks to the Kindle store in five Indian languages: Hindi, Tamil, Marathi, Gujarati, and Malayalam.

Indie authors writing in those languages were put in the ridiculous position of having to upload to Amazon via a third party aggregator to get slice of the action.
Amazon’s KDP guidelines are quite clear about what will or will not be accepted in the Kindle store.

Authors and publishers can upload and sell books with content and metadata written in the languages listed below. Content uploaded in languages that Kindle doesn’t support won’t display properly on Kindle devices and will be removed from sale.

In fact the five Indian languages were slipped onto the supported list a while ago, but only this week did Amazon make the official announcement, reported widely on the sub-continent.
To be clear, the support is only for ebooks. Despite CreateSpace being rolled into KDP as KDP Print, indie authors will not be able to make or list paperbacks for Amazon POD distribution in the Indian languages, nor in Arabic which is also limited to ebooks only.
The list also includes Japanese as ebook only despite Japanese being offered by KDP Print (but not the old CreateSpace). As so often happens, it appears not all Amazon departments are on the same page.
Anyway, here’s the “official” list of KDP-supported languages as of this morning.

Afrikaans French Northern Frisian
Alsatian Frisian Norwegian
Arabic (eBook only) Galician Nynorsk Norwegian
Basque German Portuguese
Bokmål Norwegian Gujarati (eBook only) Provençal
Breton Hindi (eBook only) Romansh
Catalan Icelandic Scots
Cornish Irish Scottish Gaelic
Corsican Italian Spanish
Danish Japanese (eBook only) Swedish
Dutch/Flemish Luxembourgish Tamil (eBook only)
Eastern Frisian Malayalam (eBook only) Welsh
English Manx
Finnish Marathi (eBook only)

The list looks impressive at first glance, but actually if we set aside Afrikaans, Arabic, Japanese and the Indian languages we are left with languages indigenous to western Europe, many of which  have speaker numbers in the low thousands (Norther Frisian 10,000 speakers, for example, or Manx which Wikipedia says has just 1,200 speakers).
Amazon has for many year now stated on its website that,

Our goal is to have every book, ever published, in any language available for Kindle customers to purchase and begin reading in less than 60 seconds.

Mainstream publishers do have some options indies don’t – Chinese, for example – but by and large it looks like that snippet from the AuthorCentral pages was written in a bygone era when Amazon perhaps seriously did see the Kindle’s global potential.
Sadly there’s no sign that’s still the case.
