Friday’s heavy snowfall over much of Japan canceled 100 aircraft, shut down dozens of roads, and interfered with rail service, according to government officials and operators.

According to the land ministry, domestic airlines such as ANA, Japan Airlines, and others had already cancelled 100 flights because of the snow as of noon.

Parts of 31 highways were closed in central and eastern Japan, while 54 central Tokyo expressway exits were blocked, the ministry said.

Services on more than a dozen train routes in central and eastern Japan had suspended operations or were planning to do so, the land ministry said.

East Japan Railway, the country’s biggest train operator, said a high-speed service between Tokyo and the northeastern prefecture of Yamagata would be suspended later on Friday.

Major delivery service firms including Yamato Transport and Sagawa Express said their delivery services may experience delays until Saturday.
