The 15th International Turfgrass Research Conference (ITRC) will be held at the Karuizawa Prince Hotel West in Karuizawa, Nagano, Japan from July 12-16, 2025. This is only the second time that the conference will be held in Japan; it was first hosted in Tokyo in 1989. Karuizawa is a popular summer resort area for the residents of Tokyo, and it has convenient access from central Tokyo.
The combined knowledge of researchers and engineers from Japan and abroad will be brought together at the 2025 ITRC to help solve “existing issues” and encourage people in industry, government, and academia to work together to create a green and rich living environment that maximizes green space in society.
The event will feature keynote speeches, a practitioner seminar, oral and poster research presentations, a zoysiagrass symposium, graduate student contest awards, as well as an all-day technical tour visiting Saitama and Nagano.
A graduate student competition will once again take place at the 2025 ITRC. Competitions will be held for oral presentations and entrants will be divided into multiple categories based on their topic of research. The top contestants in each category will receive a complimentary ITS student membership and a modest cash prize. The presenting author of an accepted manuscript must be a graduate student at the time of the 2025 ITRC to be eligible for the competition.

The International Turfgrass Society (ITS) is a non-profit scientific organization established in 1969 to encourage research and education in turfgrass science. The mission of ITS is to promote personal communication among the international community of turfgrass researchers by organizing international conferences for the dissemination of research and information on all phases of turfgrass production and use. To this end, International Turfgrass Research Conferences are held at 4-year intervals.
Past conferences have been held in the United Kingdom (1969, 2005), United States (1973, 1993, 2017), Germany (1977), Canada (1981, 2001), France (1985), Japan (1989), Australia (1997), Chile (2009), China (2013), and Denmark (2022). Following the latest conference in Copenhagen, the ITRC will be held in Japan in 2025 for the first time in 36 years.
