In July 2018, the government of Japan formulated the Strategic Energy Plan in order to show the public the basic direction of Japan’s energy policy. The Plan set the goal to raise Japan’s energy self-sufficiency rate from around 8 percent in 2016 to 24 percent in 2030. This looks unrealistic, but it’s not impossible if Japan can concentrate on the development and spread of renewable energy.

However, the Strategic Energy Plan stays ambiguous about Japan’s future energy policy, despite its aim to shed light on that very subject. One big problem with the Plan is that the priority of the energy policy is not clear. The government aims to use renewable energy as the major power source by 2030, according to the Plan — but at the same time, the plan also attempts to restore nuclear energy and raise its share to 20 percent-30 percent.

Former Prime Minister Koizumi Junichiro is well known for advocating the “zero nuclear energy” campaign after the 3.11 triple disaster. He continues to argue that Japan must be able to live without nuclear energy. In a recent talk show, he questioned the current Japanese government’s energy policy and said it was a lie to claim that nuclear energy is safe, low-cost, and clean.

Some commentators criticize Japan for being poor at decisively changing track when necessary. When the time came for Japan to give up nuclear energy once and for all, the government was not ready to make a tough political decision. In the wake of the Fukushima nuclear accident, countries such as Germany declared they would abandon nuclear energy. However, it is ironic that Japan, the direct victim of the nuclear disaster, still doesn’t dare to say goodbye to nuclear energy completely.

The Fukushima nuclear accident caused a crisis for Japan’s energy security. But it is this very crisis that could provide an opportunity for Japan to redirect its energy policy and accelerate the development of renewable energy. Despite the government’s hesitation, many Japanese already believe that nuclear energy is outdated and renewable energy is the correct direction for Japan. As recent TV programs have reported, some ordinary people are starting to invest in solar energy and sell electricity to power companies.

Japan must build confidence that renewable energy has the potential to secure its energy supply. For example, it is said that during the golden week in May 2018, 93 percent of the electricity supply in the Kyushu area was from renewable energy. If Japan could get through the past eight years nearly without nuclear energy, then it must be able to do better in the future with the spread of renewable energy.

Finally, to solve the energy problem, Japan also needs revolutionary innovation. For example, Toyota has just launched the new generation of its Mirai (Future) hydrogen fuel cell vehicle. The new Mirai not only has zero emissions, but also can produce and store electricity to provide energy in an emergency. The Toyota automobile is not only an energy consumer, but also an energy supplier. Mirai points to the future for Japan’s energy policy. Similar innovation should take place in other industries.
