The quake shook buildings in Tokyo following the warning.
A magnitude-5.3 earthquake hit Tokyo and surrounding areas on Friday evening, the Japan Meteorological Agency said, a day after the government issued a first-ever advisory about the risk of a huge earthquake on the country's Pacific coast.
The government issued an emergency warning of a strong tremor for the capital city and Kanagawa, Saitama, Yamanashi and Shizuoka prefecture, without a tsunami alert.
The quake shook buildings in Tokyo following the warning. Tokyo Metro briefly stopped at least one of its train lines but the service was quickly resumed.
