Shogi star Fujii Sota has become the first player to hold all eight major titles after winning the Oza championship.

Shogi is a traditional Japanese board game similar to chess.

The 21-year-old Fujii faced Nagase Takuya, the 31-year-old defending champion of the Oza title, in the fourth match of the best-of-five series in Kyoto on Wednesday.

The players spent a long time pondering their moves, and Nagase gradually got the upper hand. After they had both used up their allotted time, they had to make their moves within one minute.

In that situation, Nagase failed to find moves that would lead him to victory. The balance then turned to Fujii, and Nagase conceded after the 138th move of the match.

Fujii won the series with three wins and one loss.

In his hometown, Aichi Prefecture's Seto City in central Japan, fans were joyful about Fujii's feat.

At an event to watch the game's development, a couple in their 70s said their hearts pounded when Fujii was in a difficult situation, and they were happy to see his come-from-behind victory. They said they wanted to thank him, and that they hoped he will keep up the momentum.

An 8-year-old boy said he felt good when Fujii won. The boy's mother said she hopes children have a mindset of never giving up, like Fujii.

Newspaper extras were handed out in Nagoya city.

A man in his 40s said he likes shogi and has been a fan of Fujii since his debut.

A woman in her 40s said her heart was in her mouth watching the game.

Another woman in her 40s said she thought Fujii's achievement was amazing, given his young age, and that she feels as if he were a relative. She said she wants him to create new records and history.

In 2016, Fujii made his professional debut at the age of 14 years and 2 months, the youngest ever to do so.
