In 2018, after Naoki drew a GPS art message of support for victims of the Hualien earthquake, he became known across Taiwan as "Naoki Sensei" (Teacher Naoki). This led to an official Japan-Taiwan friendship meeting with the Mayor of Hualien.
In 2019, he completed a bicycle circumnavigation of Taiwan (~1,000km). Then in 2023, he achieved the unprecedented feat of running around Taiwan β 1,135km in 24 consecutive full marathons. In Taiwan, he's affectionately compared to the "third most famous Japanese person" after Hiroshi Abe and Naomi Watanabe.
