The J8M Shusui (Literally Autumn Water", used as a
poetic term meaning "Sharp Sword") was essentially the 
license production version of the Me-163 Komet.

The 2 aircraft actually differ quite a bit in performance.
Once the Germans were able to send a Komet example and some technical blueprints,
it had to be adapted to Japanese manafacturing capabilities.

As a result the copied HWK rocket engine produced 500lb less thrust.
The Japanese version was also essentially more "fragile", with the
cockpit armour plating being removed to save weight, and the Main wing spar 
and Vertical tail being built of Plywood and wood. 

It also carried less fuel and slightly less ammo. 
This ended with an aircraft 410kg lighter when empty than the Komet
but this was not enough to offset the effects of the weaker engine.
