He creates his artworks while growing vegetables and caring for his family.

Animation creator Naoyuki Niiya gave Harada some vegetables from his farm.
Niiya was Harada's colleague at an art university in Tokyo long ago, and participated in anti-government demonstrations with Harada. However, now that his parents are very elderly, he has returned to his hometown to care for them.
Even though Niiya has less and less free time every day, he continues to self-publish manga and engage in various creative activities little by little. (https://kiyubaru.exblog.jp/34380620/)

Creators are those who never stop creating, no matter what the situation.

While many Japanese creators avoid mentioning political issues, Niiya is an animation creator who simultaneously speaks out about politics, which is one of the reasons Harada trusts him.

We have a preference for creators who steadily create works while struggling with the daily reality of life, rather than creators who win big awards or make headlines in the media.
