About Us
What is Inoshi
Inoshi is a service that organizes the complex landscape of legal procedures and filing deadlines that come with starting and running a business in Japan. We compile deadlines for corporate tax, income tax, consumption tax, social insurance, labor insurance, and more — displaying them on a timeline customized to your fiscal year and business type. Each filing includes detailed explanations, submission methods, legal references, and official links.
Our Mission
We are made by enthusiasts of entrepreneurship in Japan. Japanese legal compliance involves numerous filing authorities, complex deadline calculations, and frequent regulatory changes — creating a significant barrier for first-time entrepreneurs and businesses expanding into Japan. We are working to build a healthy environment for people to build businesses in the new information technology era. Our goal is to reduce the burden of legal procedures so that entrepreneurs can focus on what matters most — their business.
