Japan’s largest online English platform with 24/7 one-on-one lessons, run by the DMM.com group.
DMM Eikaiwa is an online English-conversation service launched in 2013 and operated by DMM.com, one of Japan’s largest digital conglomerates. Headquartered in Tokyo, it is widely described as Japan’s largest online English-learning platform, and the same platform is marketed internationally under the Engoo brand.
Lessons are 25-minute live one-on-one video sessions booked on demand around the clock from a pool of 10,000+ instructors spanning 132 countries. The service supplies a large library of free, leveled teaching materials plus published textbooks and AI-driven practice tools, with no surcharge for choosing a particular teacher.
Commercially it runs as a monthly subscription, from ¥4,880/month (8 lessons) to ¥6,980/month for a daily lesson, with a Plus Native Plan unlocking native-English and Japanese-speaking instructors at roughly three times the price. The platform reports about 1 million lessons per month, suiting budget-conscious Japanese learners wanting high-frequency, flexible practice.
