On May 16, the Ishiba Cabinet submitted a pension reform bill to the Diet. After a long deliberation, the Ishiba government dropped a provision to use a reserve fund for salaried workers to offset any future decline in pension benefits. The ruling Liberal Democratic Party (LDP) was afraid that including this provision would hurt them in the coming July Upper House elections.
The opposition parties are frustrated with the pension bill. It is likely that it will be the last major piece of legislation considered during the remainder of the current ordinary session of the Diet that ends June 22.
Japan has a universal pension system which covers mostly all the residents in Japan, irrespective of their nationality. Everyone between the ages of 20 and 59 must pay premiums into the National Pension System (NPS) and receive benefits at the age of 65. Salaried workers, who make up 70 percent of the workforce, must pay additional premiums for “employee’s pension insurance” (EPI), if they make more than 106 million yen annually. The premiums for both NPS and EPI are automatically deducted from their monthly salaries.
Business owners, including farmers and fishermen, receive NPS-only benefits. In 2023, the average NPS benefit was 57 thousand yen per month. Retired salaried workers, both employees of private companies and public workers, receive both NPS and EPI benefits in proportion to their past payments. In 2023, the average total benefit was 147 thousand yen per month.
Because Japanese demographics show that the population is aging rapidly, the government introduced the “Macro-economic Slide Formula,” which automatically adjusts pension benefits based on changes in the revenue of the NPS and EPI. With fewer people of working age, the pension revenues have fallen. The financial review for the pension system in 2024, conducted once every five years, found that the ratio of the average pension benefit against the average income of workers currently paying into the NPS and EPI would drop from 61.2 percent in 2024 to 56.9 percent in 2039, even if Japan’s economy achieves a high growth rate with 1.2 percent of real GDP growth and 2.0 percent of real wage hike. That is why pension reform is necessary in the current session of the Diet.
The Ministry of Health, Labour and Welfare (MHLW) proposed to raise benefits under the NPS program because people who had paid a smaller premium in the past would receive a smaller benefit. The ministry looked at the EPI reserve fund, which has been growing, as a resource to support the added benefits.
The LDP opposed that idea. Salaried workers who look to the EPI for most of their benefits and not the NPS would object to the MHLW proposal because it would erode the EPI fund. The first action they could take would, of course, be to vote against the LDP in the next election.
The LDP has had a traumatic experience with the pension system before. The first Abe administration collapsed following a pension mismanagement scandal, which resulted in a significant defeat for the LDP in the 2007 Upper House elections.
Accepting this reality and his party’s opposition, Ishiba submitted the pension bill without any measure for raising the NPS benefit. Instead, the bill would remove “the wall of 106 million yen.” In the current pension system, only a salaried worker with an annual income of 106 million yen or more must pay an EPI pension premium. The new bill would require all workers to pay the premium, regardless of the amount of their income. Even though low-income salaried workers would now be required to pay a premium, their benefits will not be reduced.
Also missing from the pension bill is any attempt to address another demographic issue: the “employment ice age.” There is a generation of workers who graduated from college in the 1990s and 2000s after the burst of the bubble economy and who had fewer job prospects. Since they did not pay premiums during their sometimes-lengthy periods of unemployment, it is likely that they will receive fewer pension benefits than the people who were able to keep working. A rule in the pension system significantly reduces benefits for those who have made premium payments for less than 25 years.
The opposition parties are critical of the bill’s failure to provide any relief for these participants in the NPS. These parties regard help to the employment ice agers as the core of pension reform. “This is red bean roll bread without red bean paste,” is how the leader of Constitutional Democratic Party of Japan (CDPJ), Yoshihiko Noda, described the bill. In American terms, “hamburger helper without the hamburger.” The CDPJ plans to submit its own pension reform bill.
The LDP is in a quandary. If they help the employment ice agers by tapping into the EPI reserve fund, they will face anger from the salaried workers. If they do not help, the pension system will not work well for low benefit recipients. And if they fail to pass any bill, Ishiba’s government will be criticized as irresponsible. The future is murky: since the LDP is a minority government in the Lower House. It is unclear whether Ishiba’s bill will pass the Diet by the end of the session on June 22.
