About Us


Assist Solutions specializes in serving Japan’s international community with the most reliable and cost efficient IT solutions and services available. We are dedicated to providing an accommodating support for our customers’ diverse needs in both English and Japanese. We believe that our exceptional bilingual support and flexible service along with our knowledge and experience in the field are what sets us apart from the rest of the information technology industry. We understand that not being a native speaker in a country like Japan can be stressful, so we aim to make that a little more simple by providing SIM cards and pocket wifi to our international community here in Japan. 


Our mission is, and has always been since the start of operations in 2002, to provide the international community visiting or living in Japan with the IT service and support they need to enjoy their stay. With the ever advancing IT industry and the recent surge in smartphone usage around the world, we believe that the mobile Internet is one necessity that greatly adds to one’s adventures. With the mobile Internet in your hands, one has immediate access to the recommended spots, all while staying in touch with friends all across the world. We are pleased to be able to provide you with our services and hope they enrich your time here in Japan! We aim not only to provide the best technology to our customers, but also the best quality. Although there may be many new technologies that are out there in the world, we will always think of our customers first and not put out a product or service that we do not have the utmost confidence in. As a company we constantly strive to keep customers happy and we do so with our loving customer support and tech team that can answer your questions or concerns in a moment’s notice.
