Could Japanese advertising rules restrict a health claim even if the material can be imported?

Could Japanese advertising rules restrict a health claim even if the material can be imported?

What Japanese advertising rules allow is set by Japanese law, under which the company publishes no position.

The label for the NanoFlashing™ Air Filter states: “It is not a medical device and is not intended to diagnose, treat, cure or prevent disease. It works alongside ventilation and cleaning, not in place of them.” The Terms of Use state: “Do not use Site Content to diagnose, treat, or make a patient-care or infection-control decision.” They also state: “A laboratory reduction in a virus, bacterium, fungus, particle, or other endpoint does not establish a clinical benefit, fewer infections, disease prevention or treatment, or improved health.” The Terms further state that the Medical devices chapter describes a Research Application, and that it does not describe a finished product currently available from C-POLAR for that use.
