Tomato jam from Lake Toya—handmade with local ripe tomatoes. A taste of Hokkaido to take home.

Grown by Toya’s cool nights

Around Lake Toya, warm days and cool nights create a wide temperature swing. That climate concentrates sweetness and umami in every tomato.

We make our jam from ripe tomatoes harvested near Lake Toya in Hokkaido—the same landscape many visitors come to see. What grows here tastes like here.

Only three ingredients

Tomato. Sugar. Lemon juice. Nothing else—so the fruit can speak clearly.

  • Ripe tomatoes from the Toya area
  • Sugar
  • Lemon juice

Each jar is made by hand, slowly and carefully, so you still taste the freshness of the fruit.

Two faces of the same tomato

Same fruit. Two moods—like phases of the moon.

朧

Oboro

Fresh & light

Bright and gentle—closer to fresh tomato. A clean, refreshing sweetness that feels airy on the tongue.

朔

Saku

Rich & deep

Dense and indulgent—slow-cooked sweetness with a deeper tomato character. Bold enough for savory plates.

How to enjoy

Sweet or savory—both jars love company.

  1. With prosciutto

    Spoon Saku beside thinly sliced prosciutto. Salt and deep tomato sweetness make a simple, elegant bite.

  2. On yogurt

    A spoonful of Oboro over plain yogurt brightens breakfast—fresh, light, and not too sweet.

  3. Over ice cream

    Warm a little jam and pour over vanilla ice cream. Tomato becomes dessert in the best way.
