“in BEPPU” is a solo exhibition style art festival that invites a group of internationally active artists to realize art projects that take advantage of regional characteristics. In 2017, Tanaka was in charge of the exhibition visuals at the exhibition in which Anish Kapoor was invited as one of the most important artists in the field of contemporary art. For PR materials and venue sign, he adopted a mirror sheet that looks like a mirror from the mirror work “Sky Mirror,” which is a masterpiece of the artist. The letters were made to stand out by making holes in the fumaroules of gas caused by volcanic activity, which is a characteristic of Beppu, and the work “Void Pavilion V,” which deals with the holes of works by the artist.
