As a specialist in energy policy and nuclear energy, I can provide an insightful analysis of Japan's current stance on nuclear power. Nuclear power has been a significant part of Japan's energy mix, but its use has been a subject of intense debate and scrutiny, particularly in the aftermath of the Fukushima Daiichi nuclear disaster in 2011.

Following the disaster, Japan temporarily suspended operations at all its nuclear reactors for safety checks. This led to a significant reduction in the country's nuclear power generation. However, Japan has been gradually restarting some of its reactors after implementing new safety standards and measures. As of my last update, several reactors have been brought back online, but not all of them.

In April 2015, as you mentioned, courts blocked the restarting of two reactors at Takahama Nuclear Power Plant, but they permitted the restart of two reactors at Sendai Nuclear Power Plant. The Sendai Nuclear Power Plant, located in Kagoshima Prefecture, became the first to resume operations after the new safety standards were put in place.

The Japanese government has been working to strike a balance between energy security, economic considerations, and public concerns over nuclear safety. The goal mentioned for nuclear power to produce 20% of Japan's electricity by 2030 reflects a cautious approach to integrating nuclear energy back into the country's energy portfolio. This target is ambitious given the current context and the need to ensure public confidence in the safety of nuclear operations.

It's important to note that public opinion in Japan remains divided on the issue of nuclear power. Many citizens are still concerned about the safety and long-term environmental impact of nuclear energy, especially considering the country's experience with the Fukushima disaster. These concerns have led to a push for alternative energy sources and a greater emphasis on renewable energy.

On the other hand, proponents of nuclear power argue that it is a necessary part of Japan's energy strategy to meet its energy demands and reduce reliance on fossil fuels, which are subject to price volatility and geopolitical tensions. Nuclear power is also seen as a key component in achieving Japan's carbon reduction goals and combating climate change.

In conclusion, Japan is indeed still using nuclear power, but the extent of its use is subject to ongoing discussions and developments. The country is navigating a complex landscape of safety concerns, energy policy, and public opinion as it moves forward with its nuclear energy program. The government's aim to have nuclear power account for 20% of electricity generation by 2030 is indicative of a continued, albeit cautious, commitment to nuclear energy as part of a diversified energy mix.
