Is Japan building its court house before enacting the laws?

In Japan, there has been a growing rumbling among clients for some time for more transparency in the media market. This has been partly fueled by the recession but also by the increasing internationalization of many domestic companies that are looking at their media spend as an investment and asking questions about pricing and delivery that they didn't before. Inevitably there has been a lot of discussion about media auditing as the way forward, however this may not be the best solution, or at least not yet. In Japan, however, the market is already very consolidated with the top three companies buying over 40 per cent of all media, so logically the ground is ripe for media auditing.
