◎ Book structure and features

1.
PUR binding optimized for handwriting
Since the core of this textbook is 'writing' learning, it is made with a PUR binding method that allows the book to open 180 degrees without being damaged, making it comfortable to write on.

2.
Before you start learning, start with a solid foundation!
Before starting full-scale writing study, we have covered basic knowledge such as 'Japanese parts of speech and sentence structure, basic Japanese sentence patterns' in the basic foundation section to help you study more smoothly.

3.
Writing training of just 3 sentences a day, for a total of 300 sentences over 100 days.
After laying the foundation, you will become naturally accustomed to Japanese by writing '100 representative sentences + 200 applied sentences = 300 sentences in total' for 100 days. Since you only need to write 3 sentences (1 representative sentence + 2 applied sentences) every day, Japanese will be naturally imprinted in your head and remain as a 'long-term memory' that you will never forget.

4.
Master Japanese conversation and grammar simultaneously while writing.
The 300 sentences included in this textbook are sentences that naturally incorporate basic conversational patterns and basic Japanese grammar frequently used by actual Japanese people. Therefore, by following the sentences, you can naturally master basic conversation and grammar at the same time.

5.
Scan the audio QR code, listen to 300 sentences, and repeat them.
In addition to just writing sentences, we've included 100 audio QR codes in the textbook so you can practice speaking along with the sentences you've written in the native speaker's voice. You can scan them with your phone anytime, anywhere to hear and speak along with all the sentences.
(You can also download the audio from the Siwon School Japanese website (japan.siwonschool.com))

6.
Manage your daily study schedule with the 'Daily Study Check Log'
When it comes to self-study, it is very important to ‘manage your study habits.’
Therefore, after completing each day's study, we provide a 'Daily Study Check Log' so that you can manage your own study by marking the study date and checking (O) that you have completed the study.
