Inspired by a Tokidoki bag that I have, the Sakura Trees that are a famous attraction in Japan and the lovely priestess's that are the guardians of the peaceful temples. I also looked up the Japan flag and found a few images of the sun-burst version and the battle flag presentation looked really impressive and strong.
The priestess, though tranquil, carries on the proud battle flag of Japan through the cherri blossoms.
To the country that's home to all the manga and anime characters I have come to adore, thank you. I pray for the swift recovery of your land and people and eternal peace for your lost and fallen.
