Nobel laureate Susumu Kitagawa discusses Japan’s research mindset, emphasizing curiosity and persistence in scientific discovery.
In a recent interview following his receipt of the 2025 Nobel Prize in Chemistry, Professor Susumu Kitagawa shared revealing insights into the research culture that underpins Japan’s scientific achievements. Celebrated for his groundbreaking work in chemistry, Kitagawa attributed part of his success to a distinctive Japanese mindset among researchers that prioritizes unwavering curiosity and persistence.
Susumu Kitagawa, who was awarded the Nobel Prize on October 7, 2025, has been a pivotal figure in advancing materials chemistry. His research contributions have opened new avenues in the understanding of porous materials and their applications in various fields, from environmental science to energy storage. However, beyond his technical accomplishments, Kitagawa shed light on the cultural ethos that fuels Japanese scientific progress.
‘Don’t switch off the light, even in moments of uncertainty or failure,’ Kitagawa advised, using a metaphor that resonated deeply with the scientific community. He explained that this phrase encapsulates the Japanese approach to research—maintaining a steady, inquisitive mindset irrespective of obstacles.
The Japanese research environment often encourages scientists to embrace challenges as opportunities rather than setbacks. This cultural attitude fosters resilience and innovation, qualities that Kitagawa believes are essential for scientific breakthroughs. “In Japan, persistence is more than endurance; it is a form of respect for the unknown,” he remarked.
Kitagawa’s reflections come at a time when global scientific collaboration and competition are intensifying. His perspective offers valuable lessons for research institutions worldwide, emphasizing the role of mindset in driving discovery. The determination to keep ‘the light’ on speaks to the broader human quest for knowledge and the refusal to succumb to discouragement.
Educational frameworks in Japan also reinforce this ethos, encouraging students and early-career scientists to explore boldly and remain engaged with their research subjects despite difficulties. Kitagawa’s comments suggest that fostering such an environment can have lasting impacts on a nation’s scientific output and innovation capacity.
As nations strive to excel in scientific domains, Kitagawa’s insights underscore the importance of nurturing not just technical skills but also the psychological and cultural dimensions of research. His recognition by the Nobel Committee not only acknowledges his individual achievements but also shines a spotlight on the societal values that support pioneering science in Japan.
In summary, Susumu Kitagawa’s Nobel Prize win serves as both a personal milestone and a testament to the enduring and distinctive research mindset in Japan. His advice to ‘never switch off the light’ offers enduring inspiration for researchers globally who seek to advance knowledge through perseverance and curiosity.
