Particularly in junior high school and high school, visitation days where parents are free to come observe their children's classes are quite common in Japan. They're just as much to check in on your kid as they are to get a feel for how classes are conducting. While they are likely embarrassing for some children and a bit stressful for teachers, many parents look forward to seeing how their kids spend time at school.

But while a lot of parents would want to commemorate the day with pictures or a video to look back on for memories' sake, many schools understandable prohibit photography and recording to protect the privacy of students. That was the case for Tsukiyo Ono (@tsukiyo_ono), who recently attended open classes for for her daughter and son in high school.

That didn't stop Ono from finding a way to make some memories of her daughter's school days. Ono is a professional water painter, so she decided to apply her skill to watching her children's classes and sketching them--all within the brief 50 minute class period. The level of detail and effort is super impressive!

In such a brief amount of time, Ono was able to vividly capture the classes of her daughter and son, right down to the details of letters an numbers written on the blackboard. Ono says she simply sketched from what she saw, and it's safe to say she was really invested in getting some pictures to fondly remember her children's school days before they graduated. You can really get a sense for the atmosphere of the classroom.
