Cup, Mug & Bowl - Tokyo Design Studio
Meet the Yamasaku Japanese stoneware mug, in jade green. On the outside, a speckled sand-coloured stoneware crowned with a deep brown rim. On the inside, a glossy jade green glaze that reveals itself with every sip, like a small pond at the bottom of the cup. Made in Japan, this 200 ml mug is just the right size for a green tea, an oolong, or an evening herbal infusion, and is both microwave and dishwasher safe.

Raw stoneware, jade green at heart
The appeal of this Yamasaku mug lies in its contrasts. The outside is all texture: pale, sandy stoneware speckled with dark flecks, with a gentle twisted relief that wraps around the cup and down the handle. The rim is dipped in a glaze so dark it's almost black. Then you lean in, and there it is: a luminous, glassy jade green interior, its depth shifting with the light and the color of the tea.
As is often the case with Japanese glazed ceramics, the drips and mottling vary slightly from piece to piece. Your mug will never be quite identical to the one in the photo, and that's exactly what gives it its character.
200 ml: the right measure
At 200 ml, this Japanese mug holds a proper cup of tea: enough to take your time, not so much that the last sip goes cold. The thick stoneware retains heat well and feels good in the hand. Its gently flared shape lets the aromas rise freely, which works beautifully with green teas, oolongs and herbal infusions.
Made for everyday use
This stoneware mug is microwave and dishwasher safe, and fully food safe. It's equally at home with tea, coffee, hot chocolate or a herbal infusion.
Frequently asked questions
Is the jade green mug identical to the blue Yamasaku mug?
Yes: same shape, same stoneware, same 200 ml capacity. Only the interior glaze color differs. The two pair beautifully as a mismatched duo.
Does the color hold up in the dishwasher?
Yes. The glaze is fired at high temperature along with the piece, so the color won't fade in the dishwasher.
Can it be used for drinks other than tea?
Of course. Coffee, hot chocolate, herbal infusions: this mug works for any hot drink.
A simple, thoughtful gift
Paired with a Japanese green tea or a herbal infusion, this mug makes a gift that earns its place every morning. A well-made, unpretentious object you'll be glad to reach for.
