Stem cell therapy in Japan is offered under a registration framework rather than as an approved product for most conditions. A useful opening question is which category your proposed treatment falls into. Providers experienced with international patients answer this readily, and hesitation is itself informative.
Follow with questions about the specifics. What cell type is used, where it is processed, how many cells are administered, and by what route. Ask what evidence exists for your particular condition rather than for the field in general, since these answers often differ considerably from the impression given by promotional material.
Finally, ask about the parts that happen after treatment. What follow-up is included, who to contact if symptoms appear once you are home, and whether records will be shared with your own physician. These practical answers matter as much as the procedure itself, particularly for patients who will not remain in the country. Ask whether the clinic has handled follow-up for overseas patients before, and how that process usually works in practice.
