JTTAA stands for "Japanese Table Tennis Association Approved". Blades that are used in local and national tournaments in Japan must all be registered in the Japan Table Tennis Association. In the association they actually have crew to select blades in order to ensure the quality of the baldes, both imported or locally-made, are premium. Unqualified blades are not allowed to registered. So JTTAA is indeed a sign of quality, Japanese are so conscious in their effort of quality control.
