Ever since ASTEM was founded, we have placed great importance on providing a place where dreams and emotion can flourish through communication tools, keeping the concept of bettering society through technology as our touchstone. Relying on our management philosophies of creating customer-oriented products, taking on cutting-edge technology, improving our specialized skills, promoting organized management systems, and actualizing the happiness of our employees, we do our utmost in every aspect of our work.

Throughout ASTEM’s history, we have gained a wealth of experience in planning many kinds of events, all of which are cost-effective. Whether it is planning year-round events for local governments, corporations, or schools, managing academic conferences, or engaging with large- and small-scale social welfare programs, all of our work is characterized by our close relationships with the community. We offer one-stop service in both Osaka and Tokyo–everything from the selection of a venue to the production of promotional materials by our designers, to the planning, construction, and implementation of a website, to management on the day of an event.

Our specialty lies in projects involving information accessibility. ASTEM provides real-time Japanese and English subtitles at both local and international conferences and stands unrivaled when it comes to the addition of captions, sign language interpretation, and audio descriptions to pre-existing video content. ASTEM also sells the receiver for Listen With Your Eyes TV programs called Eye Dragon 4, intended for audiences who are deaf or have hearing disabilities. We also carry a receiver called TV You Can Listen To Radio, for customers who are blind or otherwise have difficulties seeing. Right after the designated management system was created and implemented by the Japanese government, we were entrusted with the management of various facilities, such as arts and culture centers, public halls, lifelong learning centers, and history and ethnic customs museums.
