How are dual citizens perceived in Japan where in opposition to the Western world, which emphasizes on the duality (100% and 100%), "ha-fus" (halfs) are considered to only be partially Japanese (50% and 50%)?

During the spring semester of 2018, I had to make a trailer for a documentary on the subject of my choice for one of my classes. I thus decided to do it on "ハーフ (ha-fus)" - dual citizens in Japan. More precisely, I decided to focus on the French and Japanese ones. This short video was made in order to put some words on certain aspects of our daily life and I thought that it could be interesting to share it.
