The scientific community and the general public have, for free, unlimited and immediate access to all content published in Kagami as soon as it is published on the Internet. This means that Kagami does not receive any income from selling subscriptions to print or view online versions of its journals or from charging "pay-per-view" fees. Therefore, Kagami needs to defray its editorial and production costs by collecting article processing charges (APCs) from authors' institutes or research funding bodies. The value of article processing charges (APCs) is  IDR 00.00. Submission to Kagami is free of charge.
