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.

1. Major title matches (headline results)

Title Term Champion (result) Challenger Score
Ryuo 18th Akira Watanabe (defended) Kazuki Kimura 4-0
Meijin 63rd Toshiyuki Moriuchi (defended) Yoshiharu Habu 4-3
Oi 46th Yoshiharu Habu (defended) Yasumitsu Sato 4-3
Oza 53rd Yoshiharu Habu (defended) Yasumitsu Sato 3-0
Kio 30th Yoshiharu Habu (won title) Koji Tanigawa 3-0
Osho 55th Yoshiharu Habu (defended) Yasumitsu Sato 4-3
Kisei 76th Yasumitsu Sato (defended) Yoshiharu Habu 3-2

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.
