A Rough Estimate of How Long It Takes to Reach 1 Dan in Go

Go 1 dan is a milestone rank that proves a certain level of strength among amateurs.

Here’s a rough guideline for how much study time you’ll need, depending on your prior experience.

If you’re starting as a complete beginner, many people take about a year to pass 1 dan.

However, if you can’t devote much time to Go, it’s not uncommon for it to take several years.

On the other hand, if you can focus intensely, you may reach it in half a year or even a few months.

If you have experience with other board games like shogi—where you’re used to reading ahead, or you already have study habits that fit you—you tend to improve faster.

What matters most is not short-term study volume, but consistency.

Building a habit of playing games and doing tsumego little by little every day is the quickest path to 1 dan.

Studying in longer blocks only on weekends is fine too, but even 15 minutes a day, every day, leads to improvement.

3 Effective Study Methods to Reach 1 Dan in Go

For those who aren’t sure what to do to pass 1 dan, here are three particularly effective study methods.

Let’s look at each in detail.

Play Games to Build Practical Experience

The most effective way to aim for 1 dan is to play lots of real games.

If you only learn knowledge in your head, you won’t develop skill you can actually use in games.

By repeatedly playing, your reading speed and accuracy, as well as your judgment, will naturally be trained.

Online Go services are recommended because you can play regardless of time or place.

You can easily find opponents that match your level.

With playgo.gg, you can enjoy games against humans or AI, so it’s a great tool for daily practice.

After each game, it’s important to review.

By looking back at where you went wrong and which moves were good, you can avoid repeating the same mistakes.

If reviewing the whole game is difficult, that’s fine—make it a habit to reflect on even just one point where you think the game was decided.

Whether you can review on your own after a game makes a big difference in how fast you improve.

Solve Tsumego to Get Stronger at Life-and-Death

It may seem plain and is often avoided, but it’s no exaggeration to say it’s the most important part of studying Go.

It develops your ability to read out variations, and your in-game decision-making improves dramatically.

Also, since the life and death of stones can heavily decide the outcome, tsumego strength often directly translates into results.

At the stage of aiming for 1 dan, it’s effective to repeatedly solve beginner-to-intermediate tsumego.

Rather than solving 10 very hard problems, aim to be able to breeze through 100 easy ones.

By repeating them, you’ll become able to judge shapes intuitively.

The key to doing it every day is to lower the hurdle as much as possible.

Even “one problem a day” is fine.

Work tsumego time into your daily routine.

For example, on playgo.gg, the home screen gives you one daily problem each from “Beginner,” “Intermediate,” and “Advanced.”

Just opening the app every day and solving these is more than enough as a first step toward building the habit.

Learn Through Books and YouTube

In addition to playing and doing tsumego, you also need knowledge input.

By learning basic knowledge such as fuseki, joseki, and tesuji, you’ll find it much easier to win.

First, here are some recommended books.

・The “Hitome (At a Glance)” Series (Mynavi Publishing)

A problem-collection series by Honorary Meijin Cho Chikun, ideal for building the fundamentals needed to aim for 1 dan.

Two especially recommended volumes are “Hitome no Tsumego” and “Hitome no Tesuji.”

If you repeat them until you can solve them at a glance, 1 dan is right around the corner.

・Go: The 7 Truly Important Ways of Thinking (Mynavi Publishing)

A book packed with the essence of Go.

If you internalize the thinking in this book, your blunders will almost certainly drop dramatically.

・Improve Your Instincts! Win More! Intensive Lessons on Stone Shape (Mynavi Publishing)

Learn “stone efficiency,” which is necessary for improving at Go.

Useful for raising your overall strength from fuseki to yose.

Next, here are some recommended YouTube channels.

・Pro Go Player Rishi Yanagisawa’s Go Classroom

A wide range of content from beginners to high-dan players, including tsumego, tesuji, game-record commentary, and talks with other players.

At the stage of aiming for 1 dan, the “Level-Up Videos for Dan Players” series is especially helpful.

・[Go] Shuma Sasaki

Explains with a focus on “what truly matters to get stronger,” making it suitable for people who want to learn fundamental thinking rather than superficial tricks.

・IGOPRO

Focused on tesuji, off-joseki lines, and explanations of patterns that frequently appear in real games, clearly explaining the reasons behind “why you play here.”

With careful explanations that even double-digit kyu players can understand, it’s recommended for aiming for 1 dan.

It’s important to try what you learn immediately in real games.

Keeping a balance with playing, and not neglecting input, will be the quickest path to 1 dan.

How to Get Officially Certified as 1 Dan in Go

Once your strength reaches the 1 dan level, you can prove your rank by getting officially certified.

There are two main ways to get certified.

Get Certified Through Tournaments

By participating in Go tournaments and achieving certain results, you can receive rank certification.

Amateur Go tournaments are held regularly across Japan, and many include divisions for kyu players as well.

In tournaments hosted by the Nihon Ki-in or local Go federations, the system is often that your rank is certified once you achieve a specified number of wins.

If it’s your first time entering a tournament, asking a local Go club or dojo can help—you’ll likely be introduced to tournaments that are easy to join.

Use the Nihon Ki-in / Kansai Ki-in Certification System

The Nihon Ki-in and Kansai Ki-in offer dan-rank certification systems through certification exams and correspondence courses.

A key feature is that even people who find it difficult to participate in tournaments can still get certified.

A common format is to solve designated problems and submit your answers.

As for difficulty, 1 dan certification problems cover a wide range of areas such as tsumego, fuseki, and joseki.

If you keep up the three study methods introduced in this article, you should be able to reach a level where passing is well within reach.

For details, please check the official websites of the Nihon Ki-in and Kansai Ki-in.

Summary

To reach 1 dan in Go, the shortest route is to consistently do three things: play games, solve tsumego, and study (input).

A rough guideline for study time is about one year, but your improvement speed changes greatly depending on whether you have the habit of touching Go every day, even a little.

Don’t skip post-game review, and for tsumego, focus on repetition of easier problems rather than tackling only very difficult ones.

For 1 dan certification, you can either participate in tournaments or use the certification systems of the Nihon Ki-in / Kansai Ki-in.

First, the initial step is to set up an environment where you can start casually.

With playgo.gg, you get AI games, tsumego, and matched games all in one place for free, so you can start practicing today.

Make good use of it and aim to pass 1 dan.
