What Is Wakoucha? Discover Japanese Black Tea in Tokyo.

KAGUWA is a specialty tea shop dedicated to wakoucha, or Japanese black tea.

Unlike the black tea many people are familiar with, wakoucha is made from Japanese tea leaves and offers a much softer, rounder flavor. It has very little bitterness, and instead carries a gentle natural sweetness along with a delicate, almost floral aroma.

At KAGUWA, the focus is not just on drinking tea, but on experiencing its fragrance.

There are no artificial flavorings — only the natural expression of the tea leaves, carefully cultivated in different regions of Japan. Each cup tells a quiet story of its origin.

The space itself is small and serene, designed to slow you down. As you sit at the counter, time seems to soften. The tea is often paired with seasonal Japanese sweets, enhancing both the flavor and the feeling of the moment.

In many ways, this experience reflects an important aspect of Japanese culture — an appreciation for subtlety, for silence, and for what is not immediately visible.

I believe that after learning how to cook Japanese food, experiencing tea in this way allows people to connect more deeply with Japan.

It becomes less about understanding, and more about feeling.

Cooking opens the door.
Tea allows you to step inside.

And somewhere in that quiet space, you may discover a different side of Japan — one that stays with you long after the journey ends.
