Hometown Stories S2022E11 - Bomb Disposal Quest in Okinawa

76 years after the end of World War II, work to dispose of unexploded munitions is still an everyday sight in Okinawa Prefecture, southwestern Japan. It will probably take 70 years to remove all of them. Renowned expert Sunagawa Masahiro has dedicated more than 40 years to finding dud explosives that still lie buried and has so far located thousands of them.

He is also dedicated to training his successors, aiming to pass on not just his skills but also the spirit of Okinawa to the next generation. The program follows his challenge.
