japan (noun) — sense 1

My own apartment, however, I was allowed to enter; and very pretty, I must say, it is. It is hung with Indian-silk, where the brightest of birds, and the gayest of flowers, disport themselves on a white ground. The screens and dressing-table are of black japan, while the mirror is set in exquisite silver filigree work, of which material are also the boxes of my toilette.
