Starting a new life in Japan and preparing for retirement there is an exciting endeavor. Given your situation—retirement plans, a modest budget, and the desire to run a small business without hiring local employees—here are some visa options and considerations that might suit your needs:1. Assess Your Financial Situation
Budget: Determine how much you can comfortably invest in starting a business and living expenses in Japan.
Retirement Savings: Ensure you have sufficient savings or income to support yourself in retirement.
2. Consider the Right Visa
Since you have a modest budget and don’t want to hire local employees, here’s a focused recommendation:

Investor/Business Manager Visa:

Investment: Although this visa usually requires a minimum investment of 5 million yen, consider whether you can manage this or look into starting a low-cost business that fits this requirement.
Office Space: Ensure you can secure a physical office space as required by the visa.
Alternative: Long-Term Stay Options:

Tourist Visa: Initially, you could start with a long-term tourist visa if available. This allows you to get a feel for living in Japan while you explore more permanent visa options.
Student Visa: If you are willing to study Japanese, a student visa could be a temporary solution. It’s a longer-term approach but can give you time to establish yourself.
3. Prepare for Moving
Language: Start learning Japanese if you haven't already. Basic proficiency will be helpful for daily interactions and business operations.
Cultural Understanding: Familiarize yourself with Japanese customs and business etiquette to make your transition smoother.
4. Seek Professional Help
Consult an Immigration Lawyer: They can provide tailored advice on the best visa option for your situation and help with the application process.
Business Consultant: If you're starting a business, a consultant can help you with the planning, legal requirements, and operational aspects.
5. Set Up Your Business
Business Plan: Develop a clear and detailed business plan. This will be crucial not only for visa applications but also for the successful operation of your business.
Networking: Build connections within the local business community to support your venture.
6. Plan for Permanent Residency
Residency Requirements: Understand the requirements for permanent residency, such as the length of stay and financial stability. Start planning early to meet these requirements.
Summary
Determine Your Budget: Ensure you have enough funds for living and business expenses.
Choose the Right Visa: Consider the Investor/Business Manager Visa if you can meet the investment requirement, or explore alternative visas for a longer stay.
Prepare for the Move: Learn Japanese and understand Japanese culture.
Seek Professional Advice: Consult with immigration and business experts.
Develop Your Business: Create a solid business plan and network locally.
Plan for Permanent Residency: Understand and prepare for the requirements for permanent residency.
Taking these steps will help you make a smoother transition to life in Japan and work towards your goals of retirement and business ownership.
