Hasumi is one of 500 or so young Japanese who join Acopia each year, paying up to $3,000 a month for training and board. The school also fixes auditions for its candidates with talent management companies that have been the driving force behind the "Korean-wave" pop culture that exploded onto the world stage in the past decade with acts such as global chart topping boy band BTS. The influx of Japanese talent that is reshaping the K-pop industry comes at a time of increasingly bitter political acrimony between the two countries that has damaged diplomatic ties.

Romania has bled out tens of thousands of doctors, nurses, dentists and pharmacists since joining the European Union a decade ago, lured abroad by what the country lacks: significantly higher pay, modern infrastructure and functional healthcare systems. The consequences are dire. Romania is one of the EU states with the fewest doctors. Nearly a third of hospital positions are vacant and the health ministry estimates one in four Romanians has insufficient access to essential healthcare. "Medical staff leaving Romania at an almost massive pace deepens the problems of the healthcare system," former health minister Vlad Voiculescu has said. "Entire hospitals are facing a major personnel deficit and entire towns don't have a family physician." REUTERS/Andreea Campeanu SEARCH "CAMPEANU HEALTH" FOR THIS STORY.
