SAYUMI TAKE

TOKYO -- Japan's latest commitments to offshore wind development are being welcomed by foreign companies seeking to grow across Asia. But achieving these expanded goals can only be realized if current projects -- which are plagued by surging costs -- succeed, experts say.

On Friday, the government submitted a bill in parliament that would allow wind power generation facilities in the country's exclusive economic zone (EEZ), which extends 200 nautical miles (370 kilometers) from shore. Currently, such projects are limited to the country's territorial waters, which is 12 nautical miles.
