# Japan restarts the world's largest nuclear power plant, which has been offline for over 14 years due to the 311 earthquake

(Agence France-Presse Tokyo, 9th) Tokyo Electric Power Company announced today that it has restarted the reactor of Unit 6 at the Kashiwazaki-Kariwa Nuclear Power Plant. This plant is the largest nuclear power plant in the world and has been offline for over 14 years due to the 2011 Great East Japan Earthquake.

According to Agence France-Presse, Tokyo Electric Power Company stated today that the Kashiwazaki-Kariwa Nuclear Power Plant, located in Niigata Prefecture, was restarted at 2 PM. Kyodo News also reported that Tokyo Electric Power Company has restarted the reactor of Unit 6 at the Kashiwazaki-Kariwa Nuclear Power Plant today.

The Kashiwazaki-Kariwa Nuclear Power Plant is calculated to be the largest nuclear power plant in the world based on potential generating capacity. On March 11, 2011, a massive earthquake and tsunami caused core meltdowns in three reactors at the Fukushima Daiichi Nuclear Power Plant, leading Japan to completely halt nuclear power generation, including the shutdown of the Kashiwazaki-Kariwa Nuclear Power Plant.

However, Japan is currently shifting towards nuclear energy to reduce its reliance on fossil fuels and achieve carbon neutrality by 2050, while also meeting the growing energy demands brought about by artificial intelligence (AI).

Japanese Prime Minister Sanae Takaichi led the Liberal Democratic Party to a landslide victory in the House of Representatives election yesterday. Takaichi advocates for promoting nuclear energy to revitalize the Japanese economy.

In January of this year, Tokyo Electric Power Company attempted to restart the reactor of Unit 6 at the Kashiwazaki-Kariwa Nuclear Power Plant, but the restart procedure was suspended just a few hours after it began due to an alarm
