The japanese legislation about FCM is named Japanese Food Sanitation Law. It forbids the sale of FCM that could contain toxic substances (substances that could be dangerous for human health).
It does not provide a positive list such as european legislation but it provides specific requirements for food packaging or articles designed to contct food substances.

Japanese legislation can be reassumed with 3 specification:

1- General specification applied to all packaging (materials)
2- Requirements established for specific packaging (materials)
3- Specification applied to functional category of packaging.

1- General specification applied to all packaging (materials)

These general specification are applied to all food packaging/materials and they regards the use of certain heavy metals. Lead must not exceed 5% in tin plating and it must not exceed 10% in metal used for containers or packaging. Also in solder used in food packaging the use of lead is limitated.
An additional limitation is related to synthetic colors that are intended to be used in packaging.They must be specifically authorized by the Japanese Ministry of Health (i.e., listed in Appendix 2 of the Ministry's Enforcement Regulations) or must not migrate to food.
The specifications also prohibit the use of di(2-ethylhexyl) phthalate (DEHP) as a plasticizer for polyvinyl chloride (PVC) used in contact with edible fats and oils or in PVC packaging for foods containing oily ingredients.

2- Requirements established for specific packaging (materials)

.Material specific standards exist for metal cans, glass/ceramic/enamel articles, and rubber articles, including nursing apparatus. Standards also exist for synthetic polymers PVC, polyethylene (PE), polypropylene (PP), polystyrene (PS) and foamed polystyrene, polyvinylidene chloride (PVdC), polyethylene terephthalate (PET), polymethyl methacrylate (pMMA), nylon, polymethyl pentane, polycarbonate (PC), polyvinyl alcohol (PVOH), and synthetic resins made from formaldehyde.
Specific tests must be performed on these materials in order to evaluate compliance with Japanese legislation.
These tests include heavy metal limits, total non-volatile extractives under specified extraction conditions, as well as limitations on volatile content and residual monomer levels for some synthetic polymers.
Specifications also exist for specific applications such as packaging for food that is pasteurized under pressure, vending machines and packaging for food sold in vending machines..
These specifications generally include performance testing (such as strength testing, tests to look for pin holes in the packaging, etc.) to demonstrate that the packaging can withstand the conditions under which it is used. Japan has also established requirements for packaging for milky products.

Near the existing mandatory specification, established by Japanese Law, many voluntary standard have been developed by various organization. These regarding the creation of "approved list" of materials that can be safely used in food contact articles.
