Career

YouTube

Fumiya established his YouTube channel, FumiShun Base, with his younger brother, Shunya, on December 2, 2015, but they did not post their first video until September 6, 2016.

While studying in the Philippines, he continued to upload videos in his YouTube channel as a means to update his parents of his whereabouts.

He started uploading YouTube contents for Filipinos on May 31, 2017. His first video was a reaction video of Sarah Geronimo's Kilometro. From then on, he started gaining Filipino subscribers.

In April 2018, his channel hit 100K subscribers awarding him with the YouTube Silver play button. On March 7, 2019, he hit the one million subscribers mark, awarding him with a gold play button.

Some notable vlogs were his song covers of Iñigo Pascual’s Dahil Sayo, Daniel Padilla’s Simpleng Tulad Mo, Juan Karlos’ Buwan, Maja Salvador’s Dahan Dahan, and Ex Battalion's Hayaan Mo Sila which was featured in Rated K.

Other notable vlogs are his auditions to PBB Otso in Araneta Cubao and Cebu.

When the channel started, Japanese was the primary language used in his videos. English subtitles were added since most of his subscribers were Filipinos. After his stint in PBB, he shifted to a mixture of English and Tagalog. Subtitles were no longer added.

This posed a problem for his growing fanbase. With the growing demand from Japanese subscribers, he established the Hiragana FumiShun Base (ふみしゅんべーす) YouTube Channel on April 13, 2020. This channel uses pure Japanese.

The main concept of the main FumiShun Base Channel's content is his exploration of the Filipino culture. When he started being active as an actor, his content shifted to his daily life as a celebrity. The dynamics of the channel shifted and the original flavor was lost. To better categorize his content, he established Fumi (later on renamed Fumi Vlogs / ふみ) on May 17, 2020. On May 25, a week after the launch, the channel has reached 10,000 subscribers.

This channel features a more personal content, leaving his main channel to focus on his exploration to the Filipino culture.

His FumiShun Base channel went back to its original content and the change was felt in the faster rise of subscribers. On June 15, 2020, he hit the 2 million subscribers mark. This was momentous for Fumiya for it is the first time that he was able to celebrate a million subscriber milestone since he was inside the PBB house in his first million.

On May 31, 2024, Sankai, as content creator uploaded a 42-minute "My Last Vlog," announcing his YouTube channel "FumiShun Base" closure to focus on himself as musician instead. His debut single, "BENG," was released on June 12.

Business Fumiya's dream was to establish his very own clothing line. Most of his business ventures are aligned to this dream.

Fumiya opened the official shop for his YouTube channel on June 22, 2019. The shop features his original designs from when he started his channel. Items were sold out on the first week.

He also did a collaboration with Livertineage Japan. His designs were released for pre-orders on February 7, 2020.

Fumiya opened FumiShun Base Hamamatsu, his first business venture, on February 16, 2020. The establishment is a museum which exhibits Fumiya's memoirs from his childhood, life as a vlogger, and his life in the Philippines. FumiShun Base merchandise are also being sold.
