How We Picked This List of Online Japanese Courses
In order to compile the most comprehensive and accurate list, the team at Coto Academy have used several criteria as our standard for measurement. First, we evaluated teacher access, whether the course offers direct access, live instruction, or none at all. Next, curriculum structure. We measured what each course offered in terms of JLPT alignment, real-world application, etc. Price is a key factor in evaluating any product, so this will be used quantitatively for transparency. With busy schedules in mind, flexibility was our last key metric; some courses offer minute-at-a-time lessons, with others having scheduled class times. Altogether, this can act as your one-stop guide for picking an online Japanese course.

Course 1: Coto Japanese Academy
Price: Group sessions from ¥1,900(~$12); private lessons from ¥3,800(~$24)
Pros: Prestigious academic institution, small class size.
Cons: Point-based, quantity-favoring pricing structure instead of straightforward pay-per-lesson.
Coto Academy checks all the boxes when it comes to learning Japanese online. The Tokyo & Yokohama based academy offers high-quality lessons online from the same teachers who lead the lessons in their classrooms. This makes it best suited for those who desire structured progression, conversational mastery, and direct access to a teacher. When it comes to course content, Coto Academy has all the bases covered. Options include part-time, semi-intensive, JLPT, and business focuses. Classes emphasize real conversations that are applicable in daily life in Japan. When choosing classes, Coto offers the option of small group sessions of six or fewer students, or private one-on-one lessons.
Course 2: Marugoto
Price: Free for self study; 6 tutor-proctored classes: 210 AUD(~$150)
Pros: Proprietary textbook pairing.
Cons: Free course lacks conversational practice & instructors.
Marugoto has the advantage of being an online platform with its own complementary textbooks. These textbooks are based upon the JF Standard for Japanese language education. This framework focuses on language learning for mutual understanding, as opposed to a strict grammar focus. Marugoto’s online courses are in a self-study format. JF Standard’s online Minato platform hosts these courses. However, there is also access to tutor-proctored group sessions. As of this moment, online courses are only available for A1 & A2 levels of the JF Standard. Because of this, there is a very low level cap for learning; however, textbooks continue through the intermediate B2 level.
Course 3: Preply
Price: 50 minute lesson rate set by tutor; however, usually ranging ¥4,000 – ¥7,000(~$25-$45)
Pros: Endless selection of tutors, many native languages supported.
Cons: Lack of quality control; lessons have no overarching standard to meet.
What makes Preply unique is its position as an online tutor marketplace rather than a rigid school structure. You can select from thousands of tutors, giving you endless control over the content of your lessons, flexibility, and one-on-one practice. With tens of thousands of tutors, Preply may be a good option if it is difficult to find Japanese courses elsewhere in your native tongue. Preply is simply the host platform, while course content is entirely created by the individual tutors. This has upsides and downsides, as Preply is not highly selective of its tutors, but the freedom allows for very customizable learning.
Course 4: Japanese Online Institute
Japanese Online Institute has a variety of different courses, structured for distinct goals, and highly qualified teachers to lead their online classes. Offering group classes as well as one-on-one, whatever your preference is, JOI offers a flexible token-based system. There is a good variety of course structures, with the focus of the structured courses being on grammar for passing specific JLPT levels. You can start any of their courses with 2 free 50-minute lessons.
Price: Monthly package plan starting at 4 lessons for ¥6,320(~$40)
Drawback: Course structure segregates grammar from conversational, instead of a comprehensive approach.
Course 5: IRODORI
Price: Completely free textbooks and course.
Pros: Great for learning survival Japanese.
Cons: IRODORI does not offer any sort of tutor or live teacher support.
IRODORI offers a free trial with a similar setup as Marugoto by pairing the course with their own published textbooks. Similarly paired with a published textbook and backed by the JF Standard, this course has an entirely different target demographic. This online Japanese course is catered to foreigners living in Japan, with the goal of teaching skills to get through everyday situations. Currently, only 3 textbooks are published, up to A2 JF Standard level, so this course is for very basic Japanese learners. If you happen to come from a Southeast Asian country, the odds are they support your native language with 10 translations from that region. The coursework is visual-heavy, making the free self-study program easy to manage.
Course 6: Duolingo
Price: Free, ad-heavy version; Super Duolingo is currently $12.99 monthly
Pros: Short, fun lessons.
Cons: No teachers or in-depth grammar explanations.
This may be a familiar name, but don’t overlook its convenience. If you are pressed for time throughout your daily schedule, Duolingo is great for short, spontaneous lessons with a genuinely large course behind it. Duolingo may not have a teacher to speak with, but it does offer interactive listening and speaking/response content. It also offers clear progression through compounding grammar and vocab lessons based on useful unit themes. The interface is built like a game, making lessons more rewarding and engaging, great for occupying occasional free time with a learning habit.
Course 7: SNG Online Japanese Language School
Price: Starting at ¥49,500(~$315) for a 30-hour course.
Pros: Ezoe Method of teaching grammar is effective for visual learners.
Cons: Private lessons are expensive at ¥7,000/hr after 6 pm.
Another established language school in Tokyo that has brought its education online in recent years. What makes this offering unique is their proprietary “Ezoe Method”. This is a visual-heavy approach to teaching grammar. They make use of flashcards and color coding to improve understanding. This may be a good choice for those of you who struggle with traditional classroom methods or reading textbooks. Their course offerings are a wide range of levels and focuses, in group or private formats.
Course 8: GenkiJacs Online
Price: 50-minute private lessons are ¥6,600(~$40); 10 lesson package includes a free bonus lesson.
Pros: Personalized curriculum, highly interactive format.
Cons: Can be intimidating for beginners and less socially outgoing learners.
Genki Japanese and Culture School is a long-standing institution with physical branches in Tokyo and Fukuoka. Offering lessons online, these at the moment are exclusively offered in private format. The lessons place a large emphasis on active, strictly Japanese communication throughout the class time. This may be a good choice for the intermediate to high-level learners who are comfortable communicating in Japanese already.
Course 9: Akira Online Japanese School TOKYO
Price: Starting at ¥37,100(~$235) per month for an N4/N5 level, once-a-week package, plus ¥30,000(~$190) initiation fee.
Pros: Personalized, JLPT goal oriented lessons.
Cons: Comparatively, very expensive.
Akira Online Japanese School offers a strategic 1-on-1 private tutoring experience for Japanese learners. Instead of casual conversation, Akira uses their own strict learning cycle consisting of: preparation assignments, intensive conversational lessons during the Zoom lesson, immediate review, and external testing such as JLPT mock-tests to measure progress. It is designed for working professionals and busy students who want a personalized program focusing on practical communication and grammar. They have a variety of lesson plans, with pricing varying by JLPT level focus. Lessons are packaged in monthly plans with 1,2, or 3 weekly lessons, and a one time fee of ¥30,000.
Course 10: NativShark
Price: As little as $15.49(~¥2,450) per month for a yearly subscription.
Pros: Much more in depth than other casual learning.
Cons: You miss out on real-time conversational practice and personalized feedback from a real teacher.
NativShark is a self-study platform designed to eliminate the guesswork of language learning. If you find traditional textbooks overwhelming, NativShark organizes everything into simple, short lessons broken down into “phases” starting from the fundamentals (N5/N4) and moving into everyday conversation. The progression is categorized into grammar lessons, vocab & kanji practice, and then dialogue listening. It would be our recommendation for solo learners who want more depth and structure than Duolingo offers, but still want to study casually instead of committing to actual live classes.
