There is so much more that we can learn from Teigo Iba. In 1894 (27th year of the Meiji era), viewing the ravaged Besshi mountains, Iba commented: “Leaving the Besshi mountains so degraded would violate the natural order.” He believed that humankind is part of nature and so to destroy nature is inimical to all that is right and proper. Whereas this sensibility looms large in the cultures of East Asia, a pioneering spirit tends to animate the cultures of Europe and the Americas, with humankind at the pinnacle of a hierarchy. This powerful idea, namely, that humankind is part of nature and nature will take revenge if people do not respect it, is deeply embedded in Japan and the wider East Asian region. So we can readily appreciate why Iba embarked on a reforestation project, which at its peak involved the planting of more than two million saplings annually. As a result, forests once more flourish on the slopes of the Besshi mountains. This devotion to the planting of trees shaped Iba’s life during his retirement.
