花びらが
風に舞うよ
春の歌
Hanabira ga
Kaze ni mau yo
Haru no uta
Petals dancing
In the wind gracefully
Song of the spring.

Contact Us
If you have any questions or need more information, feel free to reach out to us. We welcome your feedback, bug reports and feature requests. Currently the site is in Public Alpha, so there are lots of bugs that we are already aware of.
Pricing - Free
Currently all content is free. And all content will be free for a long time. Vast majority of content will be free forever. Project is open sourced, so anyone can spin up their own Hanabira server.
It is possible that in the future certain features will be paid on main production hanabira.org platform to keep servers running and to recuperate development costs. But even in such case lots of features will remain freely available forever. Functionality that might become premium covers user specific features, such as progress tracking, word banks, SRS flashcards, ... Anyways, you can always slightly tweak the source code and you have full functionality for free.

Kanjidic Project
We are using the kanji dictionary from theKANJIDIC Project.
We took the KANJIDIC2 file, which is in XML format, encoded in Unicode/UTF-8, and contains information about all 13,108 kanji. You can download the filehere.
After downloading, we extract the file to XML format. Then, we use our custom Python script to convert it to a JSON file for easier processing. The resulting JSON file is approximately 50 MB in size.
