Hikari is a publisher of journals in science, technology and medicine founded in 2005. They used to be in the DOAJ 2015, but in 2016 the publisher isn’t mentioned in the directory. The publisher didn’t change the amount of their OA APC. The majority of the journals still charge processing fees but they no longer charge publication fees in the fields of medicine and economics. This means that of their 20 journals, 4 of them no longer have publication fees. 25 percent of their journals have no publication fees. The journals that still have publication fees charge 200 EUR per page up to 8 pages and an extra 25 EUR per pages for the additional pages.
