how To start a business in Japan, first, decide on the business type (e.g., sole proprietorship, corporation). Choose a business name and register it with the Legal Affairs Bureau. Next, create a business plan and prepare the necessary documents, such as a certificate of residence and proof of capital. You’ll need to register the company with the tax office and obtain the required licenses depending on your industry. Open a business bank account, and ensure compliance with local labor laws, including employee benefits and taxes. Finally, consider working with a local accountant or legal expert for smooth navigation through regulations.
