We publish Japanese technical books on Elixir/Phoenix and Ruby on Rails under the brand OIAX BOOKS. “OIAX” included in the brand is derived from the former company name, Oiax Inc.
Unfortunately, the books on OIAX BOOKS are not available at regular bookstores, so you must order them at a bookstore or purchase them from Amazon. There are also Amazon Kindle books.
A list of books can be found at OIAX BOOKS.
At this time, there are no plans to publish technical books in languages other than Japanese. If you would like to translate and publish in another language, please contact firstname.lastname@example.org.
