“Sustainability Talks” is a symposium jointly organized by four prestigious universities: Ochanomizu University, University of Tsukuba, University of Tokyo, and Tokyo University of Agriculture and Technology. This event promises a dynamic pace, with speakers rotating every 10 minutes. We will convene 37 leading researchers to present cutting-edge research on environmental issues and sustainability across diverse fields, encompassing both humanities and sciences.

One of the highlights of this symposium is the rare opportunity to hear from professors outside your own university without leaving the University of Tokyo Campus. The event is open to everyone, regardless of university affiliation, major, or age. Non-university students are also warmly welcomed.

On Wednesday, professors from the University of Tokyo will deliver a keynote address, streamed live from the Komaba campus. On Mondays, Tuesdays, and Thursdays, professors from partner universities will present, streamed from their respective campuses.

While all sessions will be available online, there will also be in-person events and social gatherings at the Komaba campus. Additionally, selected recordings will be released post-event.

Whether you hear the terms "environmentally friendly meals" or "plant-based" and think they sound a bit expensive or out of reach, or you're already trying to be more environmentally conscious, we've selected some limited-time menus for this week that we'd like you to try. Most of the menus use soy products. You'll be able to get high-quality protein derived from soybeans, which is good for your body, and you'll also be able to reduce your meat consumption, which will help reduce your environmental impact. Why not take this opportunity to make a better choice for yourself and the environment?
