The tunnel would benefit passenger travel, with travel times around 5 hours Seoul–Osaka (1040 km) and 7 hours Seoul–Tokyo (1550 km). This would offer South Korea a chance to redefine and expand its tourism industry to include other cities and destinations besides Seoul, as the tunnel would serve as a gateway for tourists to travel with ease to and from the peninsula.[31][32] The tunnel would assist in the creation of the proposed BESETO (Beijing–Seoul–Tokyo) Highway Plan which would connect six megacities (Shanghai, Tianjin, Beijing, Seoul, Osaka and Tokyo), each having a population of greater than 10 million people.[3]
