Leave a Nest thrives to achieve global happiness by enhancing everyday life through science and education for future generation.

Leave a Nest Co., Ltd. started as a science venture company in June 2002 by 15 graduate science students. To resolve science graduate employment problems and the decline in interests for science among the younger generation, an in house training program for university students was developed and workshops in schools were also conducted. Today, we conduct more than 150 workshops per year throughout Japan. We also have a direct network with more than 100 companies, 2,000 teachers and 10,000 researchers. Together with our partners and supporting network, we aim to contribute to the world through Science and Technology by engaging in Science education, human resource training and research development projects.
