The Japanese Ministry of Health, Labour, and Welfare (MHLW) aims to improve and promote social welfare, social security, and public health services in a comprehensive and unified manner. In addition, it undertakes work to promote the improvement of the working environment, employment security, and human resource development.
Whilst in relation to regulation of nanomaterials, the majority of Asian countries lie quite far behind the US, EU and Australia, the MHLW has encouraged companies to take necessary precautions when manufacturing nanomaterials.
In a report [pdf] published by the OECD WPMN in 2010, the following developments relevant to the regulation of nanomaterials by the MHLW were outlined:
Thus, while there are no nanomaterial-specific regulations as yet, workplace safety practices are being actively promoted. The OECD WPMN report on the topic also indicates that data gathering is underway in order to support any regulatory changes necessary.
