The revised Penal Code took effect Sunday, introducing a new type of punishment called 'confinement' that combines the previous penalties of imprisonment with labor and imprisonment without labor.
This is the first revision to the criminal punishments stipulated in the Penal Code since the code's enactment in 1907. The aim is to promote the rehabilitation of prisoners and prevent recidivism by combining traditional prison labor with a new correctional program, thereby allowing each prisoner to be handled in a way that is suited to their age and individual characteristics.
The new punishment of confinement is defined as 'detaining inmates in penal institutions and requiring them to perform necessary labor and participate in the necessary program for reform and rehabilitation purposes.' Working in prison is no longer mandatory.
The revision was prompted by worsening recidivism rates and the aging of inmates. The amendment is expected to facilitate a shift to emphasizing guidance aimed at preventing recidivism among inmates. The introduction of physical rehabilitation is also envisaged for elderly prisoners who are frail.
Inmates who are deemed to have little need for the new measures will continue to primarily engage in labor in prison.
Like imprisonment with or without labor, there are two types of confinement — indefinite and fixed-term. Fixed-term confinement ranges from one month to 20 years.
The new system will be applied to incidents and accidents that took place after the revision took effect. However, inmates currently in prison and those to be sentenced to imprisonment — with or without labor — for crimes they committed before the implementation date will be handled the same way from June 1 as those who receive the new confinement punishment.

Japanese prisons to place more focus on rehabilitation than punishment
An amendment to the Penal Code placing greater emphasis on rehabilitation efforts in prison took effect Sunday, marking the first time changes have been made to the forms of punishment under Japan's more than a century-old crime laws. Imprisonment is no longer divided into the categories of with and without labor, and prison work is no longer mandatory for inmates, allowing more time to be allocated for rehabilitative guidance and education to reduce recidivism, according to the Justice Ministry. The revised law, which will affect people convicted from Sunday, stipulates anew that imprisonment consists of "confinement in a penal institution" and that inmates can be assigned to undertake "necessary work" or can undergo "necessary guidance" for rehabilitation and improvement. Prior to the change, the treatment of inmates was largely based on the likelihood of reoffending, potentially subjecting an elderly repeat shoplifter and a yakuza gang member to the same regime. The new system sets up 24 programs tailored to an inmate's age, characteristics and other factors, including a Daily Care-Senior curriculum for those aged 70 and older and suffering from dementia and Addiction Recovery targeting drug abusers. Other programs target those aged between 20 and 26, and those facing prison terms of at least 10 years. Elderly inmates are expected to be able to focus more on maintaining their physical and cognitive functions rather than engaging in typical prison work, while younger inmates will undergo a program to enable their return to school after leaving prison, according to the ministry. Inmates will be sent to prisons that can offer appropriate programs for them. Their situation will be reviewed every six months, enabling them to switch to different treatment programs if needed. Japan's Penal Code was enacted in 1907. The legislation to realize the latest change was enacted by parliament in 2022. © KYODO

Akira Amari: Japan Will Remain ‘Best Partner, Closest Ally of U.S.' as Negotiations Continue Over Trump's Tariffs
Akira Amari Japan will remain the best partner of the United States and act as a bulwark against hegemonic nations, according to former Liberal Democratic Party Secretary General Akira Amari, 75. The following is excerpted from an interview with Amari conducted by Yomiuri Shimbun Staff Writer Ryosuke Okada. *** Japan is the largest foreign owner of U.S. Treasury bonds, which could become a choke point for the United States as that can allow Japan to assert control in that realm. China is making the United States worry that it might sell off a bunch of U.S. bonds, but there will be no such worry coming from Tokyo. Japan will continue to firmly support the credibility of the U.S. economy. Japan serves as a frontline base for the United States' trust and power, acting as a bulwark against hegemonic nations such as China and Russia. It is crucial that people in the U.S. President Trump's inner circle understand the importance of Japan-U.S. relations. For Trump, the most important thing is probably be that he is able to say that he did what no one else could do. It is also important for Japan to provide answers that the United States can accept in areas in which Washington finds particularly unfair. I worked with the Economy, Trade and Industry Ministry to examine non-tariff barriers pointed out by the U.S. trade representative. We studied how Japan should respond to each of the U.S. claims and how far we could go in the negotiations before submitting the list of the items to Ryosei Akazawa, the minister in charge of economic revitalization, ahead of tariff negotiations with U.S. officials. Additional tariffs on Japanese automobiles as well as steel and aluminum products must be abolished. Increasing imports of U.S. biofuels can be an option to offset the U.S. trade deficit in these areas. However, it is impossible to eliminate the U.S. trade deficit with Japan on automobiles. One option would be to establish a Japan-U.S. working-level council to develop common 'standards' on the non-tariff barriers cited by the USTR. It should also be necessary to provide a clear explanation that Japan's U.S. auto imports will increase as long as they are attractive products, as is the case with Tesla's cars being well-accepted in Japan. I was the chief negotiator for the Trans-Pacific Partnership trade pact under the administration led by former Prime Minister Shinzo Abe. The most important thing in negotiations is to have just one contact point. I advised Chief Cabinet Secretary Yoshimasa Hayashi that his role is to coordinate among the various parties within the Prime Minister's Office as the person in charge. Negotiations would not be concluded as soon as relevant ministers tried to show their presence in their respective areas. During the TPP talks, I gathered with relevant ministers at the lawmakers' dormitory. When I asked if I was the one responsible for the negotiations, then Chief Cabinet Secretary Yoshihide Suga simply replied, 'Yes.' This allowed me to tell the U.S. side that no one but Abe can override what I say. Some people say that Pax Americana has come to an end, but the United States must continue to be a stabilizing force in the world. Otherwise, the international order will shift toward the rule by force by China, a military hegemonic power. Japan will remain the best partner and most understanding nation of the United States. Japan should be able to create a framework for the United States to lead the international community in a positive direction. Akira Amari Amari graduated from Keio University's faculty of law. After working at Sony Corp., he was first elected to the House of Representatives in the 1983 election. He has served as the head of the Economy, Trade and Industry Ministry, economic revitalization minister, LDP secretary general and chairperson of the LDP's Research Commission on the Tax System. In the Cabinet led by former Prime Minister Shinzo Abe, formed in December 2012, Amari served as the lead negotiator for the Trans-Pacific Partnership negotiations. He retired in 2024.

Japanese Defense Minister Calls for Enhancing Multinational Security Cooperation at Asia Security Summit in Singapore
Hirotaka Kuriyama / The Yomiuri Shimbun Defense Minister Gen Nakatani, right, shakes hands with Australian Defense Minister Richard Marles in Singapore on Sunday. SINGAPORE — Defense Minister Gen Nakatani called for stronger relations with like-minded countries, including the United States, to increase deterrence against China in conjunction with the Asian Security Summit in Singapore held from Friday to Sunday. As the U.S. government is increasing its pressure on allies and like-minded countries through tariff measures, Nakatani focused on maintaining multinational cooperation. After finishing his meetings at the summit, which is also known as the Shangri-La Dialogue, Nakatani told reporters on Sunday, 'I exchanged opinions with many defense ministers, and reaffirmed the need to strengthen defense cooperation and partnership.' On the same day, Nakatani met with Australian Defense Minister Richard Marles to call on the Australian government to jointly develop ships based on the Maritime Self-Defense Force's Mogami class destroyers regarding Canberra's plan to introduce a new type of ship. If joint development is realized, it is expected that interoperability between the SDF and the Australian military will be improved. Nakatani also held individual talks with the defense ministers of the Philippines and Malaysia, which are both in dispute with China over territorial claims in the South China Sea, and held bilateral meetings with a total of eight countries during his stay. The defense ministers of Japan, the United States, Australia and the Philippines held a meeting on Saturday. The meeting was aimed at maintaining U.S. involvement in the Indo-Pacific region as the Trump administration, which has been accused of disregarding its allies, has been at odds with other countries over tariff measures. The ministers confirmed that they will meet regularly in the future, expressed 'serious concern' about China's attempts to change the status quo and reconciled their perceptions of China. A trilateral defense ministers' meeting of Japan, the United States and Australia was also held on Saturday. The ministers issued a statement acknowledging the importance of partnership. Nakatani's focus on maintaining multinational cooperation, including with the United States, at the summit is aimed at preventing China, which has been making unilateral advances in the region, from taking advantage of the growing distrust of the U.S. to expand its influence in the region. On Saturday, Nakatani delivered his address at the Asian Security Summit and emphasized the importance of 'the rules-based international order.' He also proposed the cooperative framework of OCEAN (One Cooperative Effort Among Nations) so that countries sharing common values and interests will jointly expand their cooperation. 'Each of the countries also expressed similar views. I got responses indicating that all of them shared the same opinion,' Nakatani told reporters on Sunday. However, it remains to be seen whether the relationship between the United States and its allies and like-minded countries will be able to improve. A senior Defense Ministry official said, 'It will be increasingly necessary for Japan to compensate for the decline in the U.S. presence.'
