Looking for methods to study Japanese efficiently? In this article, we will learn about the “Spaced Repetition System”, abbreviated as SRS, which translates to Spaced Memorization System.
The SRS Method generally uses front-and-back Flashcards to present information to the student, where they need to try to remember the meaning or a similar idea.
In this article, we will delve deeper into the spaced memorization method, also known as the Anki method. It is a very popular method for learning the Japanese language.

The SRS Method (Spaced Repetition System)
The SRS is a learning method that uses spaced repetition to help students memorize information more efficiently. The idea behind the SRS is to present study material at increasing intervals, which helps transfer information from short-term memory to long-term memory.
Here is a more detailed explanation of how an SRS works:
- When you learn a new word, kanji, or expression, the first review is done in a short period of time (for example, a few hours or a day).
- If you remember the information correctly, the interval before the next review increases (for example, two days).
- If you continue to remember the information correctly in subsequent reviews, the interval before future reviews continues to increase (for example, four days, one week, two weeks, and so on).
- If you fail to remember the information during a review, the interval is reduced, and you start reviewing it more frequently again.
The SRS is an effective technique for learning vocabulary, kanji, and grammar in Japanese, as it helps focus on those pieces of information that are more difficult to remember while reviewing the easier information at longer intervals.
There are several tools and apps available that use SRS, such as Anki and Memrise. These apps allow you to create your own flashcards or use predefined sets of cards from other users. Additionally, they automatically manage review intervals based on your performance, making it easier to adhere to the method.
To make the most of SRS, it is important to study frequently and review the material regularly. Additionally, combining SRS with other learning techniques and practice in real contexts can further improve retention and understanding of the Japanese language.

Which tool to choose?
By using tools like Anki and Memrise, you can take advantage of SRS to enhance your Japanese learning and retain information more efficiently. However, it is important to remember that regular practice and combining different learning techniques are essential for success in mastering the Japanese language.
Spaced repetition alone is not enough; it is also essential to practice listening comprehension, speaking, reading, and writing in real contexts and apply the knowledge acquired.
Additionally, it is important to consider your preferences and learning style when choosing between Anki, Memrise, or other SRS-based tools. Some people may prefer the interface and more gamified approach of Memrise, while others may appreciate the customization and flexibility of Anki. Try both tools and see which one fits your needs and preferences best.
Manual SRS Method with Flashcards
You may have noticed that the apps used employ a Flashcard system, cards with front and back, which are perfect for learning using SRS, even if they are made manually.
To use SRS manually, using flashcards, follow these steps:
- Choose the material to be studied: This can include words in Japanese, phrases, grammar, Kanjis, or any other material you want to memorize.
- Create a list of items: Write each item to be memorized on a card or paper, with the information on one side and the translation or meaning on the other side.
- Classify the difficulty of each item: Assess how easily you can remember each item on a scale of 1 to 5, for example. Items with difficulty 1 are those you can easily remember, while items with difficulty 5 are those you have difficulty remembering.
- Create a review schedule: Based on the difficulty rating of each item, set a review schedule for each of them. Items with difficulty 1 can be reviewed every two weeks, while items with difficulty 5 should be reviewed daily.
- Review the items according to the schedule: Revisit each item on the review date and try to remember the meaning or translation before looking at the other side of the card. If you remember, place the card in the less frequent review pile. If you forget, place the card in the more frequent review pile.
- Adjust the review schedule: As you continue to review the items, you can adjust the review schedule based on your ability to remember. Items that you remember easily can be spaced further apart in your reviews, while items that you have difficulty remembering will need to be reviewed more frequently.
Using SRS manually requires a bit more organization and discipline, but it can be a great way to memorize information effectively. By adjusting the review schedule based on your ability to remember, you can optimize the learning process and make studying more efficient.

Spaced Review Table
Here is a time table you can use as a reference for reviewing items using SRS:
| Difficulty | First Review | Second Review | Third Review | Fourth Review | Fifth Review |
|---|---|---|---|---|---|
| 1 | 1 day | 2 days | 4 days | 1 week | 2 weeks |
| 2 | 1 day | 2 days | 4 days | 1 week | 2 weeks |
| 3 | 1 day | 3 days | 1 week | 2 weeks | 1 month |
| 4 | 1 day | 4 days | 2 weeks | 1 month | 3 months |
| 5 | 1 day | 5 days | 1 month | 3 months | 6 months |
Studies, Results, and Evidence
The effectiveness of spaced repetition has been demonstrated in various research studies. A 2011 study published in the Journal of Experimental Psychology showed that the use of spaced repetition significantly improves information retention compared to cramming.
See below for other studies, results, and evidence of the SRS method:
Ebbinghaus, H. (1885): The German psychologist Hermann Ebbinghaus was the first to study spaced repetition. In his pioneering work, he discovered the so-called “forgetting curve,” which describes how information retention decreases exponentially over time unless it is reviewed periodically.
Bahrick, H. P., Bahrick, L. E., Bahrick, A. S., & Bahrick, P. E. (1993): In this study, the authors found that spaced repetition is effective for long-term knowledge retention. Participants who used spaced repetition to learn vocabulary in foreign languages showed significantly greater retention of learned words, even after an interval of up to 5 years.
Cepeda, N. J., Pashler, H., Vul, E., Wixted, J. T., & Rohrer, D. (2006): In this study, the authors demonstrated that spaced repetition improves performance in learning historical facts as well as retention of words in foreign languages. They also showed that the ideal review intervals depend on the desired retention time.
Karpicke, J. D., & Roediger, H. L. (2007): This study showed that spaced repetition is effective not only for improving information retention but also for increasing understanding of the material. The authors found that students who used spaced repetition to learn expository text performed better on comprehension and retention tests than those who studied in a massed manner.
These studies and others show that spaced repetition is an effective learning technique that can significantly improve retention and understanding of information in various fields of study, including language learning such as Japanese.
