The best looking result you can achieve by using Subsurface Scattering shader.
The other options could be also:
Mix Diffuse shader with Transparent shader - this will give you visible emission material trough it.
Translucent shader - the inside of the lantern will not be affected by light.
Diffuse mixed with Translucent - will be very close to Subsurface Scattering. You will want to mix it with Transparent shader.
Note that I've bumped Emission material to 20.
