We have created a 5-7-5 method to help people memorize the map of Japan more easily. It turned out to be quite fun, so we decided to release it on Kindle and share it with a wider audience. Currently, the Kindle version is only available in Japanese, but we plan to introduce it in other languages, such as English. We would love for everyone who is learning Japanese to check it out.
