Mr Minami’s experience also includes establishing and serving as Representative Director of the Japanese subsidiary of an overseas counter-drone systems manufacturer, where he led market entry, regulatory engagement, and local business development focusing largely on the defence sector, power plants, and airports. In addition, Mr Minami has held senior business development roles with multiple international technology startups, leveraging his deep industry relationships to support strategic expansion into Japan and to secure long-term commercial partnerships.

Key Locations of Contamination Across Japan

Japan, like many other parts of the world, is facing widespread PFAS contamination in water and soil, with recent government surveys detecting levels above provisional safety standards at numerous sites nationwide, including groundwater and river systems in major prefectures such as Osaka, Tokyo, and Okinawa[1] .

PFAS contamination has been detected near several US military bases, Japanese Self-Defence Forces facilities, and civilian airports across Japan. The contamination is primarily linked to the historical use of PFAScontaining aqueous film-forming foams (AFFF) for firefighting[2] .

Significant PFAS contamination has been identified or is suspected in water sources and soil near the sites across Japan which are outlined below[3] .

The use of these chemicals has led to widespread concerns over public health and the environment in Japan, with local residents' groups calling for greater transparency and investigation into the sources of pollution.

US Military Bases and Airfields: These facilities are frequently cited as sources of contamination, particularly in Okinawa and Western Tokyo, where elevated levels have been found in nearby water sources.

• Kadena Air Base (Okinawa): The largest US Air Force installation in the Pacific, it has been associated with high levels of PFOS/PFOA in nearby rivers and springs, affecting local drinking water supplies.

• Marine Corps Air Station Futenma (Okinawa): Significant contamination concerns, and local authorities have requested access for testing.

• Yokota Air Base (Tokyo): Spills of firefighting foam occurred between 2010 and 2012, and high PFAS levels have been found in groundwater and sewage near the base.

• Naval Air Facility Atsugi (Kanagawa Prefecture): This base has reported numerous releases of AFFF, leading to contamination in a nearby river.

• Misawa Air Base (Aomori Prefecture): High levels were found in a pond that drains runoff from the base and in the local wastewater treatment plant following a pipe burst.

• Marine Corps Air Station Iwakuni (Yamaguchi Prefecture): At least 12 spills of firefighting foams were reported between 1997 and 2016.

• Camp Hansen , Camp Courtney , and Camp McTureous (Okinawa): Surveys have flagged elevated PFAS levels near these Marine Corps camps.

• Sagami General Depot (Kanagawa Prefecture): "Forever chemicals" have been found in groundwater near this Army depot.

• Yokosuka Naval Base (Kanagawa Prefecture): High PFOA concentrations were reported in the base's wastewater in 2022.

Japanese Self-Defence Forces (SDF) and Joint-Use Facilities : PFAS contamination has also been identified at Japanese military facilities and airports, linked to PFAS-containing firefighting foams.

• Komaki Airport / Mitsubishi Heavy Industry Plant (near Nagoya): Water in the region is perpetually contaminated with PFAS from the plant and joint-use airfield.

• SDF Facilities Generally : Reports indicate that contamination has been found across various Japanese military facilities, though specific site details are less publicized than U.S. bases due to different transparency agreements.

• Hokkaido Airports : PFOS and PFHxS have been detected around airports in Hokkaido, likely due to the use of fire extinguishers.

Mr Minami’s vast network is particularly valuable in tackling these critical environmental challenges, including PFAS contamination at airports and fuel depots from firefighting foam residues and petrochemical exposure, one of the largest classes of untreated environmental liabilities globally. His extensive exposure to these markets and commercial landscape in Japan will be invaluable in helping ECT establish strategic partnerships and generate commercial agreements with some of the country’s largest contaminated sites.

Commenting on the appointment of Mr Minami, ECT Executive Chairman, Faldi Ismail, said, “Hirokazu’s appointment will play a key role in the acceleration of the Company’s commercialisation strategy for our REM technology, with Japan identified as a key market.

“His extensive experience building and commercialising businesses in Japan, combined with his deep understanding of regulatory frameworks and engagement with industrial stakeholders, will be a major asset to ECT. Hirokazu brings proven operational and governance expertise across complex, highly regulated industries, which will be invaluable as we continue to develop and ultimately deploy this technology.

“Japan, like many other parts of the world, is facing widespread PFAS contamination in water and soil, with recent government surveys identifying exceedances of provisional safety standards across multiple regions largely linked to the historical use of PFAS-containing firefighting foams, particularly at defence and aviationrelated facilities.

“This creates a significant market opportunity for ECT, with strong demand for effective and scalable remediation solutions. Japan’s increasing regulatory focus and commitment to environmental protection position it as an attractive market for the deployment of ECT’s REM technology and a key contributor to the Company’s long-term growth strategy.”

In connection with his appointment to the Advisory Board, the Company will issue Mr Minami a total of 3,500,000 performance rights, which will vest and convert into fully paid ordinary ECT shares as per the below Schedule.

The Board authorises the release of this announcement.
