As an expert in the field of energy and nuclear technology, I have been closely monitoring the developments in the nuclear power sector, especially in Japan, which has a significant role in the global nuclear energy landscape. Japan, being an island nation with limited natural resources, has historically relied on nuclear power to meet a substantial portion of its energy needs.

The Fukushima Daiichi nuclear disaster in 2011, triggered by the Great East Japan Earthquake and tsunami, had a profound impact on Japan's nuclear power industry. The incident led to a nationwide shutdown of all nuclear reactors for safety checks and a reevaluation of the country's energy policy. This event also sparked a global debate on the safety and sustainability of nuclear power.

Post-Fukushima, Japan has been gradually restarting its nuclear reactors after rigorous safety assessments and upgrades. The process of restarting the reactors has been cautious and subject to public opinion, regulatory requirements, and legal challenges. The number of operational reactors has been fluctuating, with some being restarted and others being permanently shut down.

As of my last update in early 2024, Japan has a total of 43 nuclear reactors. However, not all of these are operational. The status of these reactors can change frequently due to various factors including maintenance, safety inspections, and regulatory decisions. It is important to note that the operational status of nuclear reactors is subject to change and it is always best to refer to the latest data from reliable sources such as the Japan Atomic Industrial Forum (JAIF) or the International Atomic Energy Agency (IAEA) for the most current information.

From the information provided, it is mentioned that only two reactors at Kyushu Electric Power's Sendai plant are operational as of March 9, 2016. The Sendai plant is located on the southern tip of Kyushu, one of Japan's four main islands. The restart of these reactors marked a significant step in Japan's efforts to gradually return to nuclear power generation after the Fukushima disaster.

It is crucial to understand that the number of operational nuclear power plants and reactors can be influenced by several dynamic factors including technological advancements, safety concerns, public opinion, and policy decisions. Japan's approach to nuclear power is continuously evolving, reflecting a balance between the need for stable and clean energy sources and the imperative to ensure the highest levels of safety and public trust.

In conclusion, while I can provide a snapshot of the situation as of a specific point in time, the landscape of nuclear power in Japan is subject to change. For the most accurate and up-to-date information, it is recommended to consult the latest reports and data from authoritative organizations in the field.
