The room, more spacious than a koma (smaller tearoom) of two tatami mats, yet retaining a sense of tension must be credited to Joan Urakusai, who explicitly said 'a room of two and a half or one and a half tatami mats is like a torture to the guest(s).'
二畳の小間と違ってゆとりがありかつ緊張感を失わない室内空間は、「二畳半、一畳半は客を苦しめるに似たり」と言い切った如庵・有楽斎の面目躍如と言うべきだろう。
