- Finding
- NavSource Destroyer Archive page for this hull and sister Akizuki: class listed as 'AKIZUKI (1959)'; 'Paid for with funds of the United States Military Aid Program (MDAP) and became units of the Japanese Maritime Self Defence Force'; Teruzuki - Launched June 24 1959, Commissioned February 29 1960, Decommissioned September 27 1993; displacement 2,890 tons (full); crew 330. Photo captions (from Jane's Fighting Ships 1967-68 editions and official JMSDF photographs) describe both ships as built in Japanese shipyards under the United States 1957 Military Aid Program, designed with a long forecastle hull, and employed as flotilla leaders. Confirms the U.S. hull-number assignment DD-961 for this JMSDF destroyer (DD-162 in JMSDF service).

- Limitations
- Secondary archival compilation, not a government record - its own captions cite Jane's Fighting Ships and official JMSDF photographs. Its 'Fate: Scrapped in 1993' conflicts with the reported target sinking of 14 July 1994 (see ev-uss-teruzuki-dd961-06). The page's 'Laid down by Mitsubishi at Nagasaki' describes sister Akizuki's yard; this hull's builder was Shin-Mitsubishi at Kobe per Japanese references. 'Modified Fletcher' is NavSource's class tag, not a documented design derivation. Live navsource.org served inconsistent page content to automated fetches; the Wayback capture is cited for stability.

- Finding
- Compiled service record consistent across Japanese reference works: laid down 15 August 1958 at Shin-Mitsubishi Heavy Industries Kobe; launched 24 June 1959; commissioned 29 February 1960; served as first flagship of the JMSDF Escort Flotilla from 1961; collision with cargo ship Kamoharu-maru near the Uraga channel 30 March 1963 (five crew killed); ASW refit at Sumitomo Heavy Industries Uraga shipyard September 1976 - 31 January 1977 (Weapon Alfa, Hedgehog and Mk.2 torpedo racks removed; Type-71 rocket launcher and triple short torpedo tubes fitted); reclassified auxiliary (special service ship) ASU-7012 on 27 March 1986; training ship TV-3504 on 1 July 1987; auxiliary ASU-7012 again 20 June 1991; stricken 27 September 1993.

- Limitations
- Compiled secondary references (Navypedia, uswarships.jounin.jp, kasado.net) drawing on official JMSDF data - consistent with each other but not primary sources; no JMSDF-published ship history page exists for decommissioned hulls. Navypedia lists the ASU-7012 conversion as 3.1985 while Japanese references give 1986-03-27 - the later date is corroborated by sister-ship sequencing (Akizuki converted to ASU-7010 on 1985-03-27) and is carried. 1976-77 refit scope is documented; any asbestos disturbance in that work is era inference only.

[4]Japan Defense Agency, Notification Kanshi-8755 (官施第8755号), 18 November 2005, Defense Councillor for Hygiene - 'On Appropriate Health Management for SDF Personnel Concerning the Asbestos Problem,' with attached survey results (official MOD disclosure site) [other_primary]

- Finding
- Official Japan Defense Agency notification transmitting the agency's survey of sprayed asbestos and asbestos-containing parts in buildings, equipment, ships, aircraft and supplies. Equipment results: (1) eight in-service vessels confirmed using sprayed asbestos - escort ships Hiei, Tachikaze, Shirane and Hamayuki (galley/scullery/wardroom-bathroom ceilings), transports Yura and Noto (galley ceilings and walls), test ship Kurihama (galley ceiling), submarine rescue ship Chiyoda (galley ceiling) - surfaces coated to prevent fiber release; (2) asbestos-containing parts and products confirmed in use across SDF equipment as friction material in vehicle/motor braking parts and 'as sealing material or insulation on engines and steam piping' (エンジン、蒸気管などにシール材又は断熱材として) of aircraft, ships, missiles, vehicles and supplies, with respiratory protection required during disassembly because contact with powdered asbestos is possible.

- Limitations
- Fleet-level survey; this hull is not named. The eight-ship sprayed-asbestos list covers vessels in service at survey time - Teruzuki was stricken 1993 and sunk 1994, a decade before the survey, so non-inclusion is expected and is not evidence of absence aboard. The ships' engine/steam-piping insulation confirmation is fleet-wide and era-consistent with this hull's steam plant but does not establish ship-specific asbestos content, location, or quantity.

[5]Government of Japan written answer, Tobunsho No. 17 / Naikaku-Sanshitsu-187-17 (答弁書第一七号, 内閣参質一八七第一七号), 14 October 2014, House of Councillors record (question paper: s187017) [other_primary]

- historical_record
- Finding
- Official government answer confirming that as of 8 October 2014, sixty disaster-compensation claims filed by SDF personnel (excluding general-service staff) were grounded in illness caused by work involving asbestos exposure; 23 had received determinations and 37 remained undecided (with year-by-year breakdowns given). The sponsoring question paper asserted that asbestos had been widely used in SDF buildings and self-defense vessels as fireproofing and insulation material until prohibited, that JMSDF members' asbestos-related claims were particularly numerous, and that MOD was compiling a database of asbestos-containing buildings and vessels.

- Limitations
- SDF-wide personnel record naming no vessel; the answer confirms only the aggregate claim count and disposition - it does not break claims down by service or hull. The question paper's JMSDF framing is the member's assertion, not a government finding. The referenced asbestos vessel/building database is not public and its hull coverage (including retired/disposed ships like this one) is unknown - carried in gaps.

- Finding type
- asbestos_application
- Finding
- Class/era inference: this hull carried a fossil-fueled steam plant - Navypedia records for DD-162 two sets of Westinghouse geared steam turbines with Mitsubishi CE boilers at 45,000 shp on two shafts; Japanese references describe two Mitsubishi-Combustion Engineering two-drum water-tube boilers (40 kgf/cm2, 450 deg.C) feeding two Mitsubishi-Westinghouse-type all-geared turbines. A 1958-60 steam warship would have carried period-standard thermal insulation on boilers, turbines and steam lines plus gaskets and packing, and the JMSDF's own 2005 survey (ev-uss-teruzuki-dd961-03) confirms asbestos-containing sealing/insulation products were in service on ships' engines and steam piping across the fleet. Typical applications for the type: boiler and turbine lagging; steam-line insulation and flange gaskets; valve packing; insulation in accommodation and galley spaces.

- Limitations
- Inference from class plant data and fleet-level official confirmation - no hull-specific material specification, insulation survey, or abatement record located. Boiler count varies by source (Japanese references: two two-drum boilers; English-language references: '4 boilers' - likely drum-count versus unit-count discrepancy; carried in gaps). The MOD confirmation is fleet-wide and does not name this hull.

- The Kaijinsha print article was identified through the citation trail but not directly inspected; the disposal narrative is corroborated by multiple independent secondary sources. NavSource's 'Fate: Scrapped in 1993' conflicts (the 1993 date is the striking, not the disposal). Whether hazardous-material removal (including any asbestos) preceded the sinking is undocumented - era target-ship practice is described only in secondary sources. Whatever era materials remained aboard at sinking were disposed at sea.

- No qualifying ship-specific asbestos record located: no hull survey, abatement contract, hazmat disclosure, museum documentation, or docketed case naming Teruzuki, DD-961, or DD-162 was found in the sources searched (see search_ledger). DANFS carries no entry for this hull (it was never a commissioned U.S. Navy warship - U.S. registry DD-961 was program bookkeeping for the MDAP-funded offshore procurement). The modern NVR detail page for DD-961 returns an unpopulated shell (pre-1987 disposals are not yet populated). The JMSDF official site documents only in-service ships.

- Absence of a located public record does not prove absence of asbestos aboard - the hull was a 1958-60 steam destroyer in service to 1993, and JMSDF fleet records (ev-03) confirm the era's asbestos pathways. Japanese-language official records (JMSDF fleet histories, MOD asbestos-vessel database, Kure disposal documentation) may hold hull-level detail not digitized or publicly indexed.
