For a Filipino man visiting Tokyo in May last year, the tour of the capital was supposed to be a fun sightseeing trip.

But the man collapsed after suffering a cerebral hemorrhage and was rushed to NTT Medical Center Tokyo in Shinagawa Ward for an emergency operation.

Fortunately, the surgery saved his life. But the trouble didn't stop there. As a tourist, his medical costs were not covered by Japan's national health insurance system, pushing his medical bills to an eye-popping ¥5.4 million.
