I read your post very well and very helpful.
But I am just worry about your picture.
The picture which is expressed with sun shine in stripe is used by Japan empire until 1945.
And it is used for WW2 and lots of people were killed behind this flag.
In Japanese, it is kind of きょくじつき. For Asia, it is same meaning like Hakenkreuz of Nazi
So, I don't want to blame you about this but please notice its meaning.
Thanks
