2. How articles are produced
Our articles are written with the help of generative AI.
Articles on laws and regulations are based on primary sources such as e-Gov (Japan's official law database) and publications by the responsible ministries, and cite article numbers and source links in the text.
When an article refers to current news, we use only facts we have confirmed in reports from multiple news outlets.
3. How we write
Laws, tax rates and amounts reflect the information available when the article was published. We avoid definitive statements and make our assumptions clear with phrases such as “generally” or “as a guide”.
The column provides general information, not individual legal, tax, investment or financing advice. For decisions about your own situation, please consult a qualified professional such as a licensed real estate broker, tax accountant, administrative scrivener or lawyer.
4. Updates and corrections
When laws change or we find an error, we revise the article and show the date it was updated.
If you notice an error, please let us know via our contact page or at contact@sumimotojp.com.
5. Our own services
Articles may include information about our own services, such as SUMIMOTO Hub.
