Japan Gastroenterological Endoscopy Society

What Japan Gastroenterological Endoscopy Society does

The Japan Gastroenterological Endoscopy Society (JGES, 一般社団法人日本消化器内視鏡学会) is a Japanese professional medical society founded in 1959 and headquartered in Tokyo, dedicated to advancing gastroenterological endoscopy research, education, certification, and clinical standards. JGES serves practicing gastroenterologists, endoscopists, endoscopy technicians, and nurses across Japan through eight regional branch chapters, the board-certified specialist system (消化器内視鏡専門医), the screening-certified physician system (スクリーニング認定医), and the WEGECA women endoscopist career support committee. It also engages an international audience through JGES International conferences, webinars, and a list of 24 Japanese institutions accepting overseas trainees.

The society's product portfolio spans three peer-reviewed journals (the Japanese-language journal via J-STAGE/KaLib, Digestive Endoscopy with impact factor and DEN Open open-access via Wiley), post-graduate education seminars delivered exclusively via e-learning since 2022, an endoscopy video library, a comprehensive handbook, and the Minimal Standard Terminology (MST 3.0). Its principal technology platforms include the JED Project (Japan Endoscopy Database), a multi-institution endoscopic database that feeds the JED White Paper and supports observational research, and AI Medical Device Guidelines governing clinical use of AI-based image-diagnosis support software. JGES convenes the 111th Annual Congress in 2026 at PACIFICO Yokohama and participates as a constituent society in Japan Digestive Disease Week (JDDW), alongside reciprocal programs with ESGE, ASGE, WEO/ENDO, UEG, DDW, and KSGE.

Revenue is generated through annual membership dues differentiated by age and member type (¥10,000-15,000 regular, ¥5,000 associate), event registration and hands-on seminar fees (¥1,000-10,000 per attendee tier), journal subscription and licensing income via Wiley and J-STAGE, and one-time or periodic examination and certification processing fees. JGES is governed as a nonprofit general incorporated association with no parent company, no external shareholders, and no disclosed revenue. Industrial sponsorship is concentrated among endoscopy equipment manufacturers including Olympus and Fujifilm Medical, which co-sponsor congresses, seminars, and JGES International webinars.

Scale indicators5 records

Recent moves6 records

Expansion highlights6 records

Others

• Digestive Disease Week (DDW): DDW is the largest U.S.-based GI congress where JGES participates through joint ASGE-JGES symposia. While not a society, DDW functions as a competing international platform and a relevant benchmark for JGES's own congress scale and sponsorship economics.

Broad incumbents

• United European Gastroenterology (UEG): UEG is Europe's largest GI congress organizer and a broader gastroenterology umbrella (vs. JGES's endoscopy focus). JGES participates in UEG Week and shares the same scientific publishing and CME infrastructure model, making it a comparable international society peer.
• World Endoscopy Organization (WEO): WEO is the global umbrella for GI endoscopy societies and co-hosts the ENDO congress, in which JGES participates as a partner society. WEO competes with JGES for international mindshare while also being a downstream channel for JGES's content.

Regional players

• Korean Society of Gastrointestinal Endoscopy (KSGE): KSGE is the principal Korean GI endoscopy society and an Asia-Pacific counterpart to JGES. KSGE Days is a JGES-endorsed international event, and the two societies share overlapping specialty culture, certification models, and OEM sponsorship dynamics (Olympus/Fujifilm).
• Chinese Society of Digestive Endoscopy (CSDE): CSDE is the principal Chinese endoscopy society and a relevant Asia regional peer given the large Chinese endoscopy workforce. CSDE competes for international trainees, OEM sponsorship, and journal submissions — particularly relevant to JGES International's growth path.
• Asian Pacific Society for Digestive Endoscopy (APSDE): APSDE is the Asia-Pacific regional federation for digestive endoscopy and a logical peer given JGES's geographic concentration and growing international ambitions. APSDE provides an alternative channel for regional CME and congress participation that overlaps with JGES International.

Direct peers

• American Society for Gastrointestinal Endoscopy (ASGE): ASGE is the primary U.S. professional society for GI endoscopy and JGES's flagship international counterpart. The two societies co-host the ASGE-JGES ESD course and run joint symposia at DDW, making them directly comparable as GI endoscopy standard-setters, certifiers, and congress organizers.
• Japanese Society of Gastroenterology (JSGE): JSGE is JGES's domestic sister society for gastroenterology more broadly, and the two co-organize JDDW. JSGE overlaps with JGES on hepatology and GI disease education, publishing, and congress programming in Japan.
• European Society of Gastrointestinal Endoscopy (ESGE): ESGE is JGES's formal cooperation partner and the dominant European GI endoscopy society. Both societies operate board certification, publish peer-reviewed journals (Endoscopy for ESGE), run annual congresses, and develop clinical guidelines — a near-perfect functional peer.
• Japan Society of Hepatology: Japan Society of Hepatology is a co-constituent society of JDDW alongside JGES, sharing the same Japanese specialist society model (board certification, journal publication, branch chapters, annual congress). It is a directly comparable domestic peer for governance, revenue mix, and operating scale.
