Naval Station Sasebo, located on the island of Kyushu in southwestern Japan, has served as the U.S. Navy’s forward-deployed base in the Western Pacific since the end of World War II. As one of the largest U.S. naval installations in Japan alongside Yokosuka, Sasebo supports surface combatants, amphibious assault ships, and logistics vessels of the Seventh Fleet. The installation’s port facilities, dry docks, piers, and ship repair infrastructure were built and maintained during the peak asbestos era. Publicly filed asbestos litigation records directly name Sasebo Harbor, Japan as a documented asbestos exposure location in multiple independent Navy veteran filings — establishing it as a recognized venue in the national mesothelioma litigation record.

Who Was Exposed at NS Sasebo

Navy veterans who served at Naval Station Sasebo or made extended port calls there in the following capacities may have asbestos exposure claims:

  • Shipboard engineering crew (BT, MM, HT, EN ratings) who performed pier-side maintenance during Sasebo port calls
  • Replenishment ship crew (AE, AFS, AOE) homeported at or operating out of Sasebo Harbor
  • Amphibious force crew of LHA, LPH, LPD, and LSD class vessels homeported at Sasebo
  • Shore-based maintenance workers at NS Sasebo facilities
  • Naval personnel present during Japanese commercial yard overhauls at Sasebo Heavy Industries

Veterans who served at Naval Station Sasebo or aboard vessels operating out of Sasebo Harbor and subsequently developed mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease may qualify for VA presumptive service connection under 38 CFR § 3.309(d) or civil claims against manufacturers of asbestos-containing materials used at the installation and aboard assigned vessels.

Key documents for a Sasebo claim:

  • DD-214 — service record documenting Seventh Fleet or NS Sasebo assignment
  • Ship deck logs — documenting port calls at Sasebo and maintenance periods
  • Service orders — documentation of Japan shore duty or Seventh Fleet deployment
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
