Lacks transparency. Publishes some details, but doesn't show its workers are paid and treated fairly.

Last researched 23 October 2026 · 9 sources

Japanese food maker Inaba Foods, selling canned tuna, curries and pet food.

Until Inaba traces its fish and seafood to the boat or farm and has the conditions of the people who catch or farm it checked independently, it can't show that they are free and fairly paid.

Why it's graded Lacks transparency

  • Not met: Meets 1 of 6 Good requirements.
  • Holds the grade back: It relies on fish and seafood that it can't trace to the boat or farm. That alone means a poor grade until it takes steps to trace it and check the conditions of the people who catch or farm it.
  • It isn't Harm on record, because there's no serious confirmed problem on its record.
  • Lacks transparency is still a poor grade: in supply chains like this, workers who can't be seen to be treated fairly are usually underpaid or unprotected.

How grades are decided


Good requirements 1 of 6

  • Not met: Pays a living wage, or holds a strong fair-pay certificationLiving wage: no evidence
  • Not met: Respects worker rightsMost of its products are made in countries such as Thailand and China, where unions are heavily restricted, and it has no full supply chain audit.
  • Not met: Supply chain independently audited or certified, or at least 80% made in countries with strong labour standards
  • Met: No child or forced labour findings or links
  • Not met: Names the factories or farms that make its products, or is fully certified by a scheme that holds and audits that list
  • Not met: Traces its catch to the boat or farm and has crews' or farm workers' conditions checked independently

Red flags 3

  • Red flag: No evidence it pays a living wage
  • Red flag: Hidden supply chain, mostly in countries with poor worker rights
  • Red flag: Relies on fish and seafood it can't trace to the boat or farm
  • Red flag: Fails its category's raw-material check (means Lacks transparency)

Evidence

What we found

  • Risk across the industry, not a finding about this company: fishing fleets and processing plants have some of the worst documented forced labour, including trafficked crews held at sea for years.
  • Relies on fish and seafood from fishing boats and farms, where crews and farm workers, often migrants recruited into debt, have been held for months or years, beaten and denied pay, out of reach of factory audits. It hasn't shown any steps to trace its fish and seafood to the boat or farm or have the conditions of the people who catch or farm it checked, so it's graded Lacks transparency until it does.

Research notes Inaba light tuna cans are sold in Japan in versions labelled as made in Thailand and as Japanese products; the company runs Thai subsidiaries (Inaba Foods Thailand, Thai Inaba Food) and a plant in Qingdao, China, but does not say which sites can its tuna. In a 2017 Greenpeace Japan survey Inaba, one of two firms holding about 70% of Japan's canned tuna market, had no written sourcing policy and no rules on transshipment at sea; its tuna came about 80% from the western and central Pacific and 20% from the Indian Ocean. It publishes no vessel list, crew checks or supplier list. Its Australian arm sells pet food only.
