2010 was a year of strong title defenses by Yoshiharu Habu and Akira Watanabe, and it also produced a new champion: Akihito Hirose won his first major title by taking the Oi. Here is a quick, source-backed tour of the biggest professional and women’s shogi highlights of the year.
In 2009, the modern shogi title scene featured dramatic seven game finishes in the Meijin and Oi, and a dominant sweep in the Ryuo. Below is a compact English recap of the year, with Japanese sources for readers who want to dig deeper.

For Japanese professional shogi, 2008 is remembered for two things above all: Yoshiharu Habu regaining the Meijin title (and securing the 19th lifetime Meijin qualification), and Akira Watanabe producing one of the most dramatic comebacks in modern title match history to defend the Ryuo crown.

1. The biggest story: the 21st Ryuo match and Watanabe’s comeback
The 21st Ryuo (2008 season) became famous for both its international setting and its reversal of fortune. Game 1 was played in Paris, and the title match itself turned into a rare “from 0-3 down” comeback: Ryuo Akira Watanabe lost the first three games to challenger (and Meijin) Yoshiharu Habu, then won four straight to take the match 4-3. With his 5th consecutive Ryuo defense, Watanabe also obtained the qualification for lifetime Ryuo (eisei Ryuo).
Ryuo match result: Watanabe 4-3 Habu (after trailing 0-3).
Notable detail: Game 1 was held in Paris.
2. Major title matches and champions (2008 season)
Several of the year’s biggest matches centered on Habu, who appeared repeatedly in title fights while also reclaiming Meijin. Here are a few key results from the major titles that concluded during the 2008 season.
Meijin: Yoshiharu Habu defeated Toshiyuki Moriuchi 4-2 to take the Meijin title (and obtained the 19th lifetime Meijin qualification).
Ryuo: Akira Watanabe defended against Yoshiharu Habu 4-3.
O-i (Oi): Koichi Fukaura defended against Yoshiharu Habu 4-3.
Oza: Yoshiharu Habu defended against Kazuki Kimura 3-0.
Kisei: Yoshiharu Habu took the title from Yasumitsu Sato 3-2.
3. Computer shogi: Gekisashi wins the World Computer Shogi Championship
In computer shogi, the World Computer Shogi Championship (WCSC) continued to be a major annual benchmark. The 18th tournament (2008) was won by Gekisashi (激指), with Tanase Shogi (棚瀬将棋) in second and Bonanza in third.

In the 2007 shogi season (April 2007 to March 2008), the title picture mixed long running dynasties with a few sharp turning points: Toshiyuki Moriuchi kept the Meijin, Akira Watanabe continued his early run as Ryuo, and Koichi Fukaura captured his first major title by taking the Oi from Yoshiharu Habu. (more…)
2006 was a year of familiar giants and a few clear signals of what would come next. Toshiyuki Moriuchi kept the Meijin crown, Yoshiharu Habu continued to pile up long-running title streaks, Yasuhiro Sato (Yasumitsu) collected trophies across multiple fronts, and Akira Watanabe’s Ryuo reign continued.
Shogi in 2005 featured a successful defense of the Meijin by Toshiyuki Moriuchi, another Ryuo defense by Akira Watanabe, and an especially busy year for Yoshiharu Habu, who held or won several major titles. This article summarizes the headline results and a few notable storylines from the year.
Note on seasons: Professional shogi title matches often span two calendar years. For consistency, I cite each title by its numbered term (for example, “the 18th Ryuo”) and the official season label used by Japanese sources.

2. A few 2005 storylines
Watanabe’s Ryuo defense and promotion
In the 18th Ryuo match, Akira Watanabe defeated Kazuki Kimura by four straight wins to defend the title. Japanese sources also note that this defense triggered Watanabe’s promotion to 9-dan.
Moriuchi holds the Meijin in a full seven-game match
The 63rd Meijin match went the distance. Toshiyuki Moriuchi defeated Yoshiharu Habu 4-3 to defend the Meijin title, underscoring just how narrow the margin at the very top can be even between long-time rivals.
Habu and Sato repeatedly collide in summer and autumn
Yoshiharu Habu defended both the 46th Oi and the 53rd Oza against Yasumitsu Sato, by 4-3 and 3-0 respectively. Earlier in the year, Sato defended the 76th Kisei against Habu 3-2. Their repeated high-stakes matches are one of the clearest through-lines of the 2005 season.

Shogi in 2004 was a year of shifting generations. Toshiyuki Moriuchi took the Meijin title back from Yoshiharu Habu, but the headline story at year’s end was a new name at the very top: Akira Watanabe captured the Ryūō crown for the first time.
Below is a compact, source-backed tour of the year’s biggest title matches and several other notable results (including women’s titles). The dates in the Japanese sources are written in “2004年度” terms (roughly April 2004 to March 2005), but the main title series listed here were played across 2004.
1. Major title matches (2004)
62nd Meijin (第62期名人戦): Toshiyuki Moriuchi (森内俊之) defeated Meijin Yoshiharu Habu (羽生善治) 4-2 and became Meijin again (2nd time overall).
75th Kisei (第75期棋聖戦): Yasumitsu Satō (佐藤康光) defended the Kisei title against Moriuchi 3-0.
45th Ōi (第45期王位戦): Habu won the Ōi title, defeating Kōji Tanigawa (谷川浩司) 4-1.
52nd Ōza (第52期王座戦): Habu defended the Ōza title against Moriuchi 3-1 (continuing his long Ōza run).
17th Ryūō (第17期竜王戦): Akira Watanabe (渡辺明) defeated Ryūō Moriuchi 4-3 to win his first major title.
Even from just these results, the year’s narrative is clear: Moriuchi rose to the top with the Meijin, Habu remained a constant force (Ōi and Ōza), and Watanabe’s Ryūō breakthrough opened a new chapter.
Other notable tournament results
22nd Asahi Open Shogi Championship (第22回朝日オープン将棋選手権): Habu won the tournament (final held May 25, 2004) over Kōichi Fukaura (深浦康市).
12th Ginga-sen (第12期銀河戦): Habu won again, defeating Tanigawa in the final (September 25, 2004).
25th JT Shogi Japan Series (第25回JT将棋日本シリーズ): Yasumitsu Satō won (final November 28, 2004) over Toshiaki Kubo (久保利明).
35th Shinjin-Ō (第35期新人王戦): Takayuki Yamazaki (山崎隆之) won (final November 4, 2004) over Shinya Satō (佐藤紳哉).
12th Kurashiki Tōka (第12期倉敷藤花): Ichiyo Shimizu took the title from Nakai 2-1.
What to remember about 2004
Moriuchi’s spring resurgence: winning the Meijin match against Habu set the tone for the year’s title picture.
Habu’s continuing dominance: even while losing Meijin, he still captured or defended major crowns and won big open events.
Watanabe’s arrival: the 17th Ryūō win (4-3) was a true turning point, introducing a new future long-term titleholder.

The 2003 shogi season (April 2003 to March 2004, following Japanese convention) felt like a swing year. Yoshiharu Habu reclaimed the Meijin, but the year ended with a completely different headline: Toshiyuki Moriuchi swept Habu to take the Ryuo and later wrested the Osho as well. Meanwhile, Koji Tanigawa continued to prove he could still win big matches at the very top, and a teenage challenger, Akira Watanabe, pushed Habu in the Oza.

The 2002 shogi season (April 2002 to March 2003, following Japanese convention) was a year of clear turning points. A new Meijin was crowned in decisive fashion, major titles moved between the familiar giants, and end of year results again left Yoshiharu Habu holding the game’s richest prize. Meanwhile, the annual awards highlighted both elite consistency and a quirky opening idea that was memorable enough to be recognized by name.

After a dramatic changing of the guard in 2000, the next season kept the title picture in motion. The 2001 season (April 2001 to March 2002, following Japanese convention) featured a Meijin match that went the distance again, a mid-year crown changing hands, and a late-year surge that left Yoshiharu Habu holding a familiar cluster of trophies. Meanwhile, annual awards highlighted both elite consistency and the kind of new ideas that keep opening theory alive.
