Sakata Eio (坂田 栄男, Sakata Eiju, Honinbo Eiju, 'the razor' Sakata, b. 15 February 1920 - d. 21 October 2010) was a 9-dan, Japanese, professional player. He is known for holding a former record of 64-title wins; his dominance of Japanese go through the 1960s; being the first Japanese professional to reach 1,000-career-wins; and publishing several popular go books. He was called, the Inventor of Myoshu by Go Seigen and nicknamed, 'the razor' because of his fierce and brilliant moves during complex fights. He is considered one of the strongest players of the 20th century and, by many, one of the strongest players of all time. His teacher was Masubuchi Tatsuko 6-dan.
Cho Chikun 9-dan: Sakata played a very ordinary opening. He never schemed for an advantage there. It was when the stones started to become entangled that he displayed his true power. That was when he would start to read deeply, then read some more, and then still more. Therefore, it was natural that he often discovered exquisite moves during those times. Reading was his most deadly weapon, so concepts like 'the shape of stones' or 'positional judgement' did not even come into consideration. If he could exercise his reading skill anything was possible; by always searching for the best move there was no need to make a judgement about the position. Sakata's special strength lay in his determination to always keep the pressure on, not matter how much of an advantage he might enjoy.
Like Go Seigen, Sakata played a dodging, amorphous type of game, so it was natural that they both often traded territory on a large scale (furikawari). But whereas Go traded groups based on his intuitive appraisal of the situation, Sakata would do so based on the outcome of his reading. There is a great difference between the two styles.
Sakata clearly also plays flexible go, but it differs from the flexibility of Shuwa and Go Seigen. In contrast to the latter's 'intuitive flexibility', Sakata's flexibility is based on his analytical ability. He is perhaps the type who will try anything if he decides it can be read out. This is the difference between the analytical player and the intuitive player.
Perhaps the thing I recall most vividly from my own encounters with him was the vivid energy in the moves he made.
Sakata Eio 9-dan: My strong point was always my play in the middle game. I would not try to come up with stunning moves in the opening but merely bide my time until that phase was over with. The more complicated the position become the greater my confidence in my ultimate victory. Even today when I look back on myself during my best years it seems to me that I played a truly powerful game.
Takagawa Kaku 9-dan: With Sakata intuition played the most important role during a game. Most players, including myself, analyze the overall position and decide on our moves as a result of this comprehensive overview, but for Sakata his first impression of the layout of the board was the most significant. Not only that but intuition was the essential part of his decision to 'play' a move. On an elementary level this philosophy of go is diametrically opposed to mine.
I was always celebrated in a fashion for my endgame play while Sakata was not, but I think here he was terribly underestimated. His appraisal of the largest move on the board was always startling. I have rarely encountered anyone who could calculate the value of a move as well as he. But what startled me more than anything was the way he intuitively chose even his endgame plays. I would spend hours analyzing the final moves of the games only to find that Sakata, as usual, had outfoxed me.
Sakata also played an ambitious, greedy kind of game. He was always intent on taking territory and as a result he often left weak stones scattered about the board. Yet he was unrivaled in his ability to make life for those stones (shinogi). It was simply splendid how he could create formations that defied analysis. Even top professionals like myself could not always determine if one or another of his groups could be killed or not.
If one omits Go Seigen from the list he would have to be considered the strongest player of that era.
Yamabe Toshiro 9-dan: Sakata's go can be summed up very easily: he possesses an unparalleled mastery of reading which allows him complete freedom to pursue any variation to its conclusion. Also, his skill in the middle game is incomparable, whether he is attacking, lightly sidestepping a blow or making eyes for an endangered group of stones. He displays a bewildering array of moves, counter-moves, feints, and thrusts. His play is fluid and lively, never static. It is when the position becomes most complex that he plays his best.
As a professional I can usually predict correctly 80 per cent of the time what the next move will be during a game. But Sakata has a knack of proving my predictions false time and time again. I find myself thinking, 'Indeed, what a clever move that is.'

Sakata Eio is author of many books in Japanese. His Sakata no Go series, aimed at dan players, is still in print after more than forty years. The Fiery Games of Master Sakata Eio is a collection of self-commented games and has been reprinted in various forms since its publication in 1991.
- Upon becoming Honinbo for the first time, Sakata chose the name Honinbo Eiju (本因坊栄寿).
- In 1953, he beat Go Seigen in a Six Game Match, 4-1-1, taking a B-W-B handicap.
- In 1964, Sakata became the first person to hold both the Meijin and the Honinbo titles simultaneously and won seven titles (with a game record of 29-2).
- Sakata set a record with 64-title-match wins. Among Japanese professionals, the record was held until Cho Chikun broke it between 1999-2000.
- Sakata played 1,787 official games, with a record of 1,117-wins, 654-loses, and 16-jigos. He was the first Japanese professional to reach 1,000-wins.
- He retired in 2000 at the age of 80.
- Up until the 1990s Sakata and Takagawa Kaku played more games against each other than any other rivals in Japanese tournament history: 97. Sakata led the series by the lopsided score of 74-wins, 21-losses, 1-jigo and 1 unclear result. Takagawa once remarked, "... if Sakata had never arrived on the scene I surely would have captured dozens more titles."
- The game shown in the famous profile image (see image above) is from the 22nd Honinbo Final, game 5, 1967-06-12 against Rin Kaiho.
- In 1990, at the age 70, Sakata narrowly missed challenging for the 45th Honinbo Final due to a special rule in the case of a multiple ties. He lost his game in the final round, against Rin Kaiho, putting his record at 5-2 and initiating a three-way tie. He would have become the oldest player to challenge for a big title.
 Sakata was nicknamed 剃刀 (kamisori), which means razor. Razor sharp (the previous translation) would be something like 剃刀のような.
