Rick your right, all of the south east asia matchlocks (Japan, Vietman, Malaysia) were based on the ones made in Goa India which used the short lived European (Bohemian) version of the snap matchlock but the Indians used the Ottoman style matchlock as did the Arabs.

When the Japanese first saw the matchlocks that the Portuguese brought with them to Japan in 1543 they had nothing else to base their own version on. There is some evidence that the Chinese prefered the Ottoman style matchlocks.
