They use this tea pot and other similar models. I've had both gyokuro and sencha from it many times and both have always been wonderful.
I was concerned about the leaves having room to spread out and not being full immersed in the water.
However this teapot is less wide and taller, doing the same job, just vertically It holds only about 1.5 cups and when I've put 1 cup in it is about 2/3 full so the leaves are well immersed in the water and spread out in the basket.
The basket makes it much more easy to clean and the glass exterior is very aesthetically pleasing. The lighting hits it in such a way that makes the green in sencha come out more.
