This special issue calls for papers of instrumentation and scientific results related to the Akatsuki Venus mission. The core of the issue will be characterization papers for 6 scientific instruments onboard Akatsuki (UVI, IR1, IR2, LIR, LAC, and RS). In addition to these, papers based on data analysis (either Akatsuki or else), modeling, and theoretical studies are welcome. The goal of this issue is to become a reference guidebook for Akatsuki data users with good example research papers.
