Since the Great East Japan Earthquake which struck on March 11, 2011, Japanese companies have realized the importance of adaptation to address climate change issues. Some Japanese companies that implement BoP in developing countries have consequently shifted their focus on harmonizing their BoP and adaptation businesses with the aim of expanding the market and creating social impact. The next challenge is to create the "triple leap" that can contribute to three improvements: raising BoP income; preventing a decrease in BoP income caused by climate change; and halting the progress of climate change through clean technology. All three improvements are important for the creation of a sustainable world. If companies are contributing to only one of these improvements, they have huge potential to evolve towards the other two.
