The Nagado Daiko has approximately 1.6 Shaku or 19 inch diameter heads and are 18-20 inches tall.
I use white oak barrels and they can be ordered with white or natural steer heads and your choice of stain - Natural, Red Mahogany, Ebony or Red Oak. I can also do a gloss black paint.
This one is a Red Oak finish.
$900 - $1,800 depending on finish and heads
Here it is on the stand getting a first stretch of a white cow hide head.
We can also build any custom size drum with your choice of wood. Of course availability, cost and delivery will change a bit....
