Yes I can agree with what Komusu said... I had to chuckle when he said that as an 'ex shakahuchi player'.... 
It's precisely that reason that many people pick up the shakahuchi and then quit. The deep sound is harder to get than the higher pitched sound of a smaller transverse flute or for instance a penny whistle.
Though the the lower deep sounding Shakahuchi is my favorite of flutes. It does require a ton of practice and discipline... but then so does anything good.
