At the 2004 convention, the party revised the program to accept for the time being the country having the Emperor and the Self-Defense Forces — a drastic shift from its previous opposition to the institutions. Although the changes were made in hopes of attracting political independents, the JCP saw its membership decline to around 270,000 in 2020 after peaking at around 500,000 in 1990. The number of subscribers to its Shimbun Akahata newspaper, the main funding tool for the JCP, which does not receive state subsidies, dropped to around 1 million in 2020 from 3.55 million in 1980. The JCP lost seats in both last year's Lower House election and Sunday's Upper House poll.
