The following represents an overview of the modern naval fighting capabilities of the Japan Maritime Self-Defense Force (2022). The service currently counts 102 total units in its active naval inventory. This total includes frontline commissioned vessels but excludes smaller patrol vessels, auxiliary / survey ships, replenishment, and historical ceremonial types. The WDMMW review takes into account specific categories of warships covering attack, defense, and general support designs. Inventory numbers and related unit types are provided as-is and derived from publically-available information / sources. "On Order" totals found at the bottom of this article are related to any future hulls currently under procurement/construction though said hulls may not be delivered for service in the current year for various reasons.

Age plays a vital role in the life of any warship as hulls and various onboard technologies are pushed to the limit, ultimately exposed to the corrosive and generally unforgiving effects of life at sea. Such degradation often leads to modernizations, refits, or outright retirement. Our color gauge attempts to showcase a vessel's current state within the fleet, helping to detail those outgoing vessels against those at the midway point of their service or those just having been commissioned.
