Voters across Japan are casting ballots in the second round of local elections to pick mayors and local assembly members. The races coincide with two Lower House by-elections that are seen as a bellwether for the Upper House elections this summer.
One of the by-elections is taking place in Okinawa. The ruling and opposition blocs are effectively facing off over plans to relocate a US airbase within the southern prefecture. The constituency, Okinawa's number-3 electoral district, includes the Henoko district of the city f Nago, where the central government is carrying out land reclamation to relocate the US Marine Corps' Futenma Air Station.
