Entry Description

「hiroma and koma」

Nanaha Co, Ltd is a company that sends the “new form
of Japan” to the world through “mattcha”. They
provide high quality mattcha in menus that are
arranged modernly, such as mattacha latte. The space
inside the shop is desired to be a “modern tearoom”,
not a “Japanese style tea room”. According to the
owner, it is a way of expressing their feeling to make a
shop that allows the customers to enjoy the traditional
Japanese culture with a modern interpretation.

In Japanese tea ceremonies, tea rooms that are larger
than 4.5 tatami floor is called hiroma while venues
smaller than that are called koma. Tea rooms that are
exactly 4.5 tatami floor can be used both as hiroma
and koma.
In koma, no shelves, including daisu, are used. Tea is
made in the preparation area and then brought to the
room. Opposed to koma, where decorations are only
placed on the floor, in hiroma, tea is prepared inside
the room, where many decorations as well as shelves,
including daisu, are used. So to say, koma is the
world of wabi-cha and hiroma is that of shoin.
At nana’s green tea UMEDA KITA GRAND FRONT, I
have placed booths that are smaller than 4.5 tatami
floor. As the decoration inside the booths is very
plain, the customers can feel the atmosphere of koma.
However, if you look from outside, the booths look
like the decorations of hiroma. In other words, I have
created a modern tea room space, where you can feel
the two types of tea rooms that differ in size.
