展覧会『SAND ROOM (Emptiness passport in a handful of sand)』にて、訪れた人に一握りの砂をおさめた、砂の旅券（パスポート）を発券しました。それぞれの砂の旅券には、その時までに流出した砂の総重量を表したシリアルナンバーが振られています。
砂の旅券を通して流出していく砂は、同じ砂の上にいた人々が互いに地続き上に存在しているということを表します。
At the "SAND ROOM (Emptiness passport in a handful of sand)" exhibition, visitors were issued with the "Emptiness Passport" containing a handful of sand. Each passport was assigned a serial number representing the total weight of sand that had flowed out by that time.
The sand that flowed out through the passports represents that the people who were on the same sand existed on the same land as each other.
