The 17th Annual PACTRIMS Congress
We are delighted to announce that the 17th Annual PACTRIMS Congress will be held from 13 to 15 November 2025 in the vibrant city of Osaka, Japan. Following our successful gathering in Bangkok last year, we look forward to reconvening in Osaka—a city renowned for its rich history, dynamic culture, and exceptional hospitality.
This year's congress will take place at The Ritz-Carlton, Osaka, an elegant venue situated in the heart of the Umeda district. Known for its blend of 18th-century European charm and modern luxury, the hotel offers state-of-the-art conference facilities, including the Grand Ballroom, which can accommodate up to 1,500 guests.
Osaka, often referred to as "Japan's kitchen," is celebrated for its culinary delights, from street food favorites like takoyaki and okonomiyaki to Michelin-starred restaurants. Beyond its gastronomic offerings, the city boasts a wealth of cultural landmarks, including the historic Osaka Castle and the bustling Dōtonbori district.
In 2025, Osaka will also host the World Expo, highlighting its commitment to innovation and global collaboration. This international event underscores the city's role as a hub for forward-thinking ideas and cultural exchange.
We invite you to join us in Osaka for an engaging and enriching congress experience.

A WELCOME NOTE FROM OUR LOCAL ORGANIZING CHAIRPERSON, PROF. KAZUO FUJIHARA
Dear Colleagues and Friends,
On behalf of the Local Organizing Committee, it is my great pleasure to invite you to the 17th Annual Congress of the Pan-Asian Committee for Treatment and Research in Multiple Sclerosis (PACTRIMS), taking place 13–15 November 2025 at The Ritz-Carlton Osaka.
Following the successful gathering of our community at the 16th Congress in Bangkok, where we strengthened regional and global collaborations, we are excited to bring this year’s meeting to the dynamic city of Osaka, known for its rich cultural heritage, innovation, and warm hospitality. PACTRIMS will return to Japan for the second time following the 6th Annual Congress of PACTRIMS which was held in Kyoto in November 2013 and hosted by Prof. Takahiko Saida, the first President of PACTRIMS.
This year’s congress will center around six key scientific themes that reflect both global advances and region-specific challenges in the field of MS and related disorders:
- Biomarkers and disease measurement in MS and other diseases
- How to manage aged patients
- PIRA and mechanisms of progression in MS
- MS, NMOSD and MOGAD criteria: Asian perspectives
- Meeting therapeutic needs in Asia
- Clinical academic careers and mentorship pathways
These themes aim to foster deep scientific exchange while addressing the evolving landscape of neuroimmunology in Asia. The program will feature plenary lectures, symposia, interactive sessions, and poster presentations, as well as focused opportunities for early-career professionals to engage in mentorship and career development.
Osaka offers a unique setting where tradition and progress coexist—from the historical beauty of Osaka Castle to the modern vibrancy of the Dōtonbori district. We hope this congress not only enriches your professional knowledge but also provides time for cultural discovery and meaningful connections.
As Professor of Multiple Sclerosis Therapeutics at Fukushima Medical University and Director of the MS & NMOSD Centre, STRINS, it is a true honour to serve as the Local Organizing Chairperson. I look forward to welcoming you to Japan and to an exciting, inspiring, and forward-looking PACTRIMS 2025.
Yōkoso! Welcome to Osaka, and welcome to PACTRIMS 2025.
Warmest regards,
Kazuo Fujihara, MD, PhD
