2025 Naturalization Data Analysis: Chinese Nationals Lead for Second Consecutive Year—Essential Insights for Foreign Residents and Employers in Japan

Introduction: Understanding the Shift in Japan’s Naturalization Landscape

In March 2025 (Reiwa 7), the Ministry of Justice released the latest naturalization statistics, revealing a significant milestone in Japan’s immigration history.

In 2025, 9,258 foreign nationals obtained Japanese citizenship. Of these, 3,533 were Chinese nationals—marking the second consecutive year that China topped the list by country of origin.

Historically, with the exception of 1973, Korean and North Korean nationals had consistently represented the overwhelming majority of naturalizations in Japan. However, in 2024 (Reiwa 6), Chinese nationals surpassed this group for the first time, and this trend continued in 2025.

This shift represents more than a statistical change. It reflects the settlement patterns of foreign residents, the increase in long-term residents, and Japan’s evolving multicultural society.

As a licensed administrative scribe (gyoseishoshi) specializing in visa applications and residence status procedures, I will analyze this latest data in detail and provide practical information for foreign residents in Japan and for employers who hire foreign nationals.

1-2. A Historic Turning Point: Chinese Nationals Lead Naturalizations

Except for 1973, Korean and North Korean nationals had consistently represented the largest group of naturalizations due to the historical presence of Zainichi Koreans dating back to Japan’s colonial period.

However, in 2024, Chinese nationals (3,122) surpassed the Korean/North Korean group for the first time. In 2025, Chinese nationals maintained their lead with 3,533 naturalizations.

Background factors include:

• Increased influx of Chinese students and workers since the 1990s
• Long-term residents transitioning to settlement and family formation
• Naturalization decisions driven by children’s education and career prospects
• Stable employment and career development in Japanese companies

1-3. Recent Trends in Naturalization Numbers

According to the Ministry of Justice, the highest number of naturalizations since annual statistics began in 1967 was 17,633 in 2003. In recent years, naturalizations have ranged from 7,000 to 9,000, with fluctuations influenced by economic conditions.

Gap between Applications and Approvals:

• Annual applications: approximately 14,000
• Approvals: approximately 9,200
• Approval rate: approximately 65%

This means that not all applications result in approval. Meeting requirements and proper document preparation are crucial.
