Disassembly Toyota Mark II or Nissan Skyline in underground mines is not a myth, but a real practice that is actively discussed in the automotive community. Main reason: Japan has strict environmental laws JAMA Recycling Law, obliging the recycling of 95% of vehicle components. Mines are used as an alternative to traditional disassembly when it is necessary to isolate toxic materials (for example, mercury sensors in older models Mazda RX-7) or disassemble the machine with minimal impact on the environment. But how legal, safe and profitable is it?

In 2023, Rosprirodnadzor recorded 12 cases of illegal import into Russia of parts from mine disassemblies - mainly suspensions Subaru Impreza WRX STI and gearboxes Mitsubishi Lancer Evolution. The problem is that such parts often do not have certificates, and their technical condition cannot be checked without specialized equipment. Meanwhile, in Japan itself, mine dismantling is regulated Law on Industrial Safety in the Mining Industry (Article 66), but exporting parts from such sources remains a gray area.

Why are Japanese cars dismantled in mines?

The main reason is controlled environment. Mines provide:

  • πŸ”Ή Stable temperature (10–15Β°C all year round), critical for dismantling plastic bumpers and rubber seals, which crack due to temperature changes.
  • πŸ”Ή No moisture β€” in underground tunnels the humidity does not exceed 40%, which prevents corrosion of metal parts during storage.
  • πŸ”Ή Isolation of toxic materials: Lead-acid batteries, freon from air conditioners and oils are disposed of without the risk of entering groundwater.
  • πŸ”Ή Protection from vandals: rare models are stored in the mines (for example, Honda NSX Type R 1992), which can be looted in open areas.

Second factor - space saving. In Japan, landfill space is limited, and mines can accommodate up to 500 cars per 1000 mΒ² (versus 50 in an open area). For example, in the prefecture Fukushima the mine is operating Kamaishi Mine, where up to 200 cars are dismantled per month - mostly Toyota Crown and Nissan Cedric 1990–2000s.

If you buy parts from mine dismantling, require a certificate JAMA Recycling Certificate β€” it confirms that the components have been tested for radiation contamination (relevant for cars from Fukushima Prefecture).

Disassembly technologies: how it works in practice

The process starts with deactivation of dangerous systems:

  1. Fuel and oils are drained (including from the power steering and automatic transmission).
  2. Airbags turn off (SRS) - they are disposed of separately due to pyrotechnic charges.
  3. Batteries and electronics (units) are dismantled ECU, sensors ABS).

Next, the car is disassembled modular principle:

Module Disassembly time Specifics of the mine method
Body 4–6 hours Use hydraulic shears with remote control (due to the risk of rock collapse).
Engine and gearbox 2–3 hours Dismantling is carried out on suspended platforms to avoid contact with mine dust.
Electronics 1–2 hours All boards are checked for short circuits due to high concentrations of metal dust.
Interior 3–4 hours Seats and panels are cleaned with steam under a pressure of 120 atm. to remove fungus.

Features of mine dismantling - use of robots. For example, in a mine Hitachi Mine use manipulators Kawasaki RS08N, which are able to disassemble Mitsubishi Pajero in 8 hours (versus 12 hours manually). The robots also scan parts for microcracks using ultrasound - this is critical for suspensions and steering racks.

πŸ“Š How do you feel about buying parts from mine dismantling?
I trust if there are certificates
I only buy new or from open salvage yards
I would never take a chance
I don't know what it is

In Russia, purchase of parts from Japanese mine disassemblies not directly prohibited, but there are pitfalls:

  • πŸ“œ Customs regulations: Parts must be declared as "used" with country of origin. Without this, they may be confiscated under article 16.3 Code of Administrative Offenses of the Russian Federation (β€œViolation of customs rules”).
  • πŸ”§ Technical regulations: brake and steering parts (e.g. calipers Brembo with Nissan GT-R) must have a certificate of conformity TR TS 018/2011.
  • ☒️ Radiation control: cars from Fukushima, Miyagi and Iwate prefectures are tested for gamma radiation. Exceeding the norm of 0.23 ΞΌSv/h is grounds for disposal.
⚠️ Attention: In 2023, the Federal Customs Service of Russia blocked a batch of engines Toyota 2JZ-GTE from the mine Osarizawa β€” the documents contained incorrect VIN codes. Buyers lost 1.8 million rubles.

In Japan, mine disassembly is legal, but the export of parts is regulated Law on control over the export of strategic goods (Export Trade Control Order). For example, turbines Garrett GT28 with Subaru WRX may be blocked for export if they were dismantled in the prefecture's mines Akita (military facilities are located there).

Which parts from mines are dangerous to buy (and why)

Not all components from underground dismantling sites are created equal. The risk group includes:

  • πŸš— Suspension: shock absorbers Kayaba and racks Tein lose up to 30% efficiency due to mine vibration.
  • ⚑ Electronics: blocks ECU from Honda S2000 often have contact corrosion due to hydrogen sulfide in the mine air.
  • πŸ”₯ Fuel system: tanks and tubes from mines Ibaraki may contain traces of methane - this is a risk of explosion during repairs.
  • πŸ›‘οΈ Body panels: on Mazda RX-8 Often there are microcracks from rocks that are not visible to the naked eye.

Critical point: Parts from mines in Fukushima Prefecture may have hidden defects due to radiation exposure. For example, rubber seals Nissan 350Z becomes fragile 5–7 years after dismantling, even if it looks normal outwardly.

1. Require a certificate JAMA Recycling indicating the mine

2. Check parts with an ultrasonic flaw detector (service cost: ~3000 rub.)

3. Test electronics on a bench (especially units ABS and SRS)

4. Measure background radiation with a dosimeter (standard: up to 0.2 Β΅Sv/h)

How to distinguish parts from the mine from normal disassembly

There are 5 key signs:

  1. Marking: parts from mines are often stamped MINE RECYCLE or UNDERGROUND DISASSEMBLY.
  2. Metal color: components from mines Hokkaido have a grayish tint due to treatment with an anti-corrosion compound Zincrometal.
  3. Smell: new parts smell like plastic, while mine parts smell like dampness or sulfur.
  4. Documents: the invoice must contain a note Subterranean Source.
  5. Price: parts from mines are 15–25% cheaper than analogues from open dismantling (for example, an engine RB26DETT costs ~250,000 rubles. versus ~320,000 rub.).

If the seller avoids questions about the origin of the parts, this is a reason to be wary. For example, in 2026 at Avito 3 fraudulent schemes involving the sale of β€œmine” turbines were identified IHI, which in fact turned out to be counterfeits from China.

List of mines where cars are legally dismantled in Japan

Kamaishi Mine (Iwate Prefecture) - specializes in Toyota and Lexus.
Hitachi Mine (Ibaraki Prefecture) - sorts out Nissan and Infiniti using robots.
Osarizawa Mine (Akita Prefecture) - works with rare models Mazda and Mitsubishi.
Besshi Mine (Ehime Prefecture) - recycles cars older than 20 years.

Alternatives to mine dismantling: which is safer?

If you are looking for parts for restoration JDM-auto (for example, Nissan Silvia S15), consider these options:

  • πŸ”§ Official showdown in Japan: companies Japan Auto Recycle and Car From Japan They provide parts with a 6 month warranty.
  • 🌍 European warehouses: in Germany (ATU) and the Netherlands (Japanparts.nl) store parts from open disassemblies.
  • 🏭 New spare parts: for models up to 2005, analogues from Febi or Meyle (the price is higher, but there are no risks).
  • πŸ”„ Exchange between owners: on the forums JDM Buyers or NissanSilvia.com They often sell used parts with a proven history.

Cost of parts from alternative sources:

Detail Mine dismantling (β‚½) Official showdown (β‚½) New (β‚½)
Engine SR20DET 180 000 240 000 450 000
checkpoint Getrag 280 (for Mitsubishi Evo) 90 000 120 000 280 000
Turbine Garrett GT2860 45 000 65 000 120 000

Parts from the mines are only beneficial for rare models (for example, Toyota Chaser JZX100), where new parts are not available. For mass-produced cars, the risks outweigh the savings.

FAQ: Frequently asked questions about mine dismantling

Is it possible to import an engine from a Japanese mine into Russia?

Yes, but required:

  1. Declaration indicating the HS code (for example, 8407.34.000.0 for gasoline engines).
  2. Certificate of Conformity TR TS 018/2011 (registration cost: ~15,000 rub.).
  3. Radiation control report (if the car is from Fukushima).

Without documents, the engine will be confiscated at customs.

Which mines in Japan are the most reliable for dismantling?

Top 3 proven mines:

  • Kamaishi Mine β€” has been operating since 1998, specializing in Toyota and Lexus.
  • Hitachi Mine β€” uses robots, 1 year warranty on parts.
  • Osarizawa Mine - sorts out rare ones Mazda and Mitsubishi, but parts are 10–15% more expensive.

Avoid mines in Fukushima Prefecture - high risk of radiation contamination.

How to check if the parts from the mine are fake?

Verification methods:

  1. Request a photo of the part with markings MINE RECYCLE.
  2. Check the VIN code of the donor car through the service CarVertical.
  3. Use an ultrasonic flaw detector for metal parts (check cost: ~2000 rubles).

Counterfeits are often sold without documents or at a suspiciously low price (for example, an engine 2JZ-GTE for 100,000 rub.).

What parts from the mines can I buy without risk?

Safe to buy components:

  • Glass (windshields and side windows).
  • Plastic bumpers and spoilers.
  • Seats and interior elements (if they do not have electric drives).
  • Wheel rims (if there are no cracks).

Avoid buying electronics, suspension and fuel systems.

What happens if you buy a part from a mine with radiation?

Consequences:

  • Fine from Rospotrebnadzor up to 50,000 rubles. for the circulation of hazardous waste (Article 8.2 of the Code of Administrative Offenses of the Russian Federation).
  • Confiscation of the car if the part is installed and exceeds background radiation.
  • Health risk: prolonged exposure to even weak radiation (0.1–0.3 ΞΌSv/h) increases the likelihood of cancer.

Before purchasing, check the parts with a dosimeter (for example, Raex Pro for 8000 rub.).
