The Japan Sports Council (JSC), which is managing the construction of the new stadium for the 2020 Tokyo Olympics, has announced that it will not use the Sourcing Code for Sustainable Timber that has been published by the official Tokyo Organising Committee for the Olympic Games (TOCOG). Rather, stadium construction will abide only by current regulations, which rely on corporate self regulation and which have been subject to longstanding criticism by NGOs and other experts. Due to inadequate regulation, it is estimated that as much as 12 percent of timber imported by Japan may have been logged illegally, a level far higher than that of other advanced economies. 

The Sourcing Code published by TOCOG has also been criticised by NGOs as 'inadequate and unsustainable'.
