This is perfectly legal and is used everywhere. Google "Minimum Advertised Price" or MAP. In Ireland, for example, there is a MAP on alcohol, meaning that you cannot advertise or sell alcohol below a certain price.
I think that people misunderstand what this is about. Tamiya is not putting up their prices. Tamiya will not make more money from this. This does not change the normal retail price. Tamiya wants to make sure that if there is a sale, the sale discount cannot go below a certain threshold. Tamiya wants to make sure that a retailer cannot use Tamiya as a "loss leader". Google "loss leader". You will still get your discounted Tamiya kit in a sale, if there is a genuine sale, such as Black Friday or a Christmas Sale.
This will protect honest traders from dodgy dealers and in turn it will protect the customers.
