Kure Line Tunnel呉線トンネルOP12026-08-03See EP2 2:40. In theory it could be the exit of any tunnel along the Kure Line, but while searching along the route this tunnel stood out as an unnecessary extra: under 30 m long, built only to pass through a single isolated rock mass, a notable engineering curiosity, so it is included here. Presumably the cost of detouring exceeded the cost of a tunnel.
