Cairn 70



This monument was erected on the occasion of Toyota Motor Corporation’s 70th anniversary. The form which looks like a reversed cone is derived from a model of ‘Minkowski Spacetime’ in physics. The model represents the hope to grow into the future in harmony with the earth. The monument contains 221 pieces of memorial stones which are donated from affiliates of Toyota Group around the world. The rhythmical arrangement of the stones is based on the Pythagorean musical intervals that conveys the intention of harmonious global network of the group in the future.
