Mr. Jean-Claude Kei Tago, Mr. Miura's colleague in his LUXMAN days, who played the role of the general manager for overseas operation, simultaneously formed his own international trading company KT International Ltd. at the time of foundation of A & M Ltd. (Air-Tight), in order to set up the world-wide marketing strategy and promote the overseas sales of the Air-Tight gears under the tight collaboration with Mr. Miura.

Both of them, forming an optimum partnership since then, have been boasting of the ever-unchanged cooperation under the tight friendship; this is the key point of the success of the Air-Tight brand in the global Hi-End Audio market.
