Which country has the strongest navy among China, Russia, Japan, South Korea, and North Korea (excluding submarines)?

 As of my last knowledge update in January 2022, the evaluation of naval strength involves various factors such as the number and capability of vessels, naval aviation, technology, and overall military capabilities. It's important to note that these rankings can change over time due to new developments, acquisitions, or geopolitical shifts.

As of recent years, China has been investing significantly in its naval capabilities and has emerged as a major maritime power. The Chinese navy, officially known as the People's Liberation Army Navy (PLAN), has been modernizing its fleet, expanding its maritime presence, and developing advanced naval technologies.

Russia has a long-standing naval tradition and possesses a formidable navy, with capabilities such as aircraft carriers, submarines, and surface ships. However, economic factors have influenced the pace of modernization and maintenance of its naval forces.

Japan and South Korea also maintain strong naval forces, equipped with modern technology and a focus on maritime security. Both countries have capable navies that contribute to regional stability.

North Korea, on the other hand, has a more limited naval capability compared to the other countries mentioned. While it has a substantial number of vessels, including submarines, the overall naval strength of North Korea is generally considered less advanced than that of China, Russia, Japan, and South Korea.

It's important to check the latest sources and assessments from military analysts to get the most up-to-date information on the naval strengths of these countries, as geopolitical dynamics can evolve over time. Additionally, the exclusion of submarines in your question may impact the overall assessment, as submarines often play a crucial role in naval capabilities.
