Japanese tea pots

Hey teafriends

I got this japanese teapot for my greens, but it is so big, 450 ml, and I am used to gongfu style. It is difficult with japanese greens tho, they are so fragile

How should i use this? Make a big brew with less leaves and let it steep longer or on the contraty i should use less water, more leaves, shorter steep times?

Thank you all :)
