Royal Sky Lounge is Akita Airport’s private waiting room on Domestic Terminal 2F. Official materials list a ¥1,100 walk-up fee, a roughly 06:50–20:25 use window, and complimentary soft drinks from a self-service vending machine. Many Japanese gold-tier cards enter free with a same-day boarding pass; reception confirms eligibility. Priority Pass does not list AXT. Separate paid group/special lounges exist for hire but are booking products, not walk-up PP alternatives.
