Minowa Yasuo makes a small number of Matcha bowls. This ash-glazed bowl is beautiful, and although it doesn't really have a left-hand side stamp in the style of Raku-yaki tea bowls, you can use Minowa's stamp as a guide.
It provides a nice contrast to matcha and has the right kind of austerity for matcha, with enough of the character of the fire that you will always know this one is yours.
