NPB All-Time Wins Leaders: Kaneda’s 400 and the Last Pitchers Chasing 200

Masaichi Kaneda won 400 games in Japanese professional baseball. No one else has reached 360, and no one ever will again. Japan’s single-season record of 42 wins is higher than the modern MLB mark of 41, which tells you something about how both leagues used to treat starting pitchers — and how completely that has changed. Here are NPB’s career and single-season wins leaders, why the numbers collapsed, and the handful of active arms still chasing 200.

Key Takeaways

• Kaneda’s 400 career wins is the NPB record. For scale, MLB’s leaders are Cy Young at 511 and Walter Johnson at 417.
• Victor Starffin (1939) and Kazuhisa Inao (1961) share the single-season record at 42 wins — one more than Jack Chesbro’s post-1900 MLB record of 41.
• In Japan, 200 career wins is the pitching benchmark for the Meikyukai, the honor society that requires 2,000 hits from position players. It functions roughly as MLB’s 300-win club does.
• NPB starters work on six days’ rest, roughly 25 starts a season, against about 30 to 33 in MLB. That structural difference caps modern win totals below 20.
• Yu Darvish (208) and Masahiro Tanaka (203) have cleared 200 across both leagues. Masanori Ishikawa, at 188 and age 46, is the closest to doing it in NPB alone.

Franchise notes for readers new to NPB: the Kokutetsu Swallows became the Tokyo Yakult Swallows, the Nishitetsu Lions became the Saitama Seibu Lions, the Nankai Hawks became the Fukuoka SoftBank Hawks, and the Hankyu Braves became the Orix Buffaloes. The Kintetsu Buffaloes were absorbed into Orix in 2004 and no longer exist.

Masaichi Kaneda: 400 wins

Kaneda is the only 400-game winner in Japanese history and, by consensus, the greatest pitcher the country has produced.

He signed with the Kokutetsu Swallows at 17 in 1950 and spent most of his prime piling up victories for a bad team — which makes the total more remarkable, not less. A heavy fastball and a sharp curve did the work.

The supporting numbers are the ones that will not be touched: 14 consecutive seasons of 20 or more wins, 4,490 career strikeouts, 365 complete games and 5,526.2 innings.

He was also fastidious about his own maintenance, building routines and a diet around keeping his left arm intact — unusual for the era. After moving to the Giants he remained an ace, and reached 400 wins in 1969.

Tetsuya Yoneda: 350 wins

Yoneda ranks second with 350, and his nickname captured why: opponents called him the Gasoline Tank, for a fuel supply that never seemed to run out.

He joined the Hankyu Braves in 1956, reached double-digit wins in his second season, and then did it 18 years in a row.

The durability markers are extraordinary. His 949 career appearances rank second all-time behind Hitoki Iwase’s 1,002, and his 5,130 innings rank second behind Kaneda’s 5,526.2.

He pitched through punishing schedules without a major arm injury, starting and relieving as needed. It is a career that the modern division of labor makes literally impossible to repeat.

Masaaki Koyama: 320 wins

Koyama won 320 games on the strength of what may be the best control in Japanese baseball history. They called him the Precision Machine.

He arrived at Hanshin as a tryout signing in 1953, an unknown, and worked his way to the front of the rotation on sheer volume of practice. In 1962 he won 27 games and carried Hanshin to the pennant.

After a trade to the Tokyo Orions — the franchise now known as the Chiba Lotte Marines — he kept winning, and became the first pitcher to record 100 victories in each of Japan’s two leagues.

His philosophy was simple and unfashionable: refuse to walk anyone, live at the bottom of the zone. It produced 74 career shutouts, third all-time, and it still reads as an instruction manual for pitchers.

The comparison worth making: 42 wins exceeds the modern MLB record of 41, set by Jack Chesbro in 1904. Only the 19th-century American totals — Old Hoss Radbourn’s 60 in 1884 and the rest — sit above Japan’s mark.

Victor Starffin: 42 wins (1939)

Starffin was the dominant right-hander of Japanese baseball’s early years and the first pitcher to reach 300 career wins.

In 1939, as the Giants’ ace, he won 42 games. That total has never been beaten, only matched, by Inao in 1961.

He stood 191 centimeters, unusually tall for the era, and threw downhill at hitters who had seen nothing like it. That season he appeared in 68 games and worked 458.1 innings.

His life outside baseball was harder than his pitching line suggests. Starffin was a Russian émigré whose family fled the revolution, and he built a career in a country that regarded him as a foreigner throughout. Asahikawa, in Hokkaido, named its ballpark Starffin Stadium in his honor.

Kazuhisa Inao: 42 wins (1961)

Inao matched the record 22 years later as the unquestioned ace of the Nishitetsu Lions, and the workload behind it was, if anything, heavier: 78 appearances and 404 innings in 1961.

His nickname was Iron Arm, and the moment that made him a permanent part of Japanese baseball lore came in the 1958 Japan Series. Nishitetsu lost the first three games. Inao then pitched four in a row and won all four, and the country produced a phrase that survives today: Kami-sama, Hotoke-sama, Inao-sama — “God, Buddha, and Inao,” ranking him with the divine.

Precise command and a hard slider were the tools. Pitching on no rest, repeatedly, was the job.

Jiro Noguchi: 40 wins (1942)

Noguchi won 40 games in 1942, and the innings total attached to it is the largest in Japanese history: 527.1, with a 1.19 ERA.

Set that against a modern NPB starter’s 150 to 180 innings and the scale becomes hard to process.

The detail that makes him singular, though, is that he hit too. On days he did not pitch, Noguchi played the field, and he put together a 31-game hitting streak that stood as the Japanese record — a mark that still ranks among the longest ever.

A two-way player carrying a wartime roster on both sides of the ball, decades before anyone used that phrase.

How a Pitcher Earns a Win in NPB

NPB scores wins under the Official Baseball Rules, the same code MLB uses, so the mechanics will already be familiar: a starter must complete five innings, leave with the lead, and have the bullpen hold it. Relievers face no innings minimum and can be credited when their team takes the lead while they are in the game, or when the official scorer judges them the most effective reliever after a starter departs early with a lead.

The part worth emphasizing is the dependency. A win requires run support and a bullpen that does not blow it, neither of which the pitcher controls. It is the least individual of the traditional pitching statistics — a fact that matters a great deal to everything below.

Why Showa-Era Aces Could Reach 30 Wins

Rest and pitch counts

Thirty-win seasons happened because pitchers were used in ways that would now be considered malpractice.

There was no concept of six days’ rest. Front-line starters went on two or three days, and sometimes on consecutive days. They also picked up wins in relief between starts, which roughly doubled their opportunities compared with a modern ace.

Nor was there a pitch limit. The complete game was a moral good, and pitchers built their craft around it — not throwing maximum effort to every hitter, but pacing themselves across nine innings. That is how a single arm absorbed 400-plus innings in a year, and how the win totals climbed to where they did.

Mechanics and conditioning

The delivery philosophy differed too. Rather than hunting 150 kilometers per hour on every pitch, Showa-era starters worked from the lower body in a smooth, repeatable motion, and dialed effort up or down depending on the hitter. Conserving energy was a skill, not a compromise.

Conditioning was built on distance running rather than sports science. Pitchers ran long and often to build the leg strength that short rest demanded, and the prevailing theory held that arms got stronger by throwing more. The sheer training volume of the era produced bodies that could survive the schedule.

Why 20 Wins Is the Modern Ceiling

Bullpen specialization

Twenty wins is now the realistic maximum, and specialization is the main reason.

The old ace aimed to finish what he started. The modern one hands off: starter, middle relief, setup, closer, in defined roles. Once a starter passes the fifth inning and approaches 100 pitches, the game leaves his hands.

Which means a pitcher can be flawless, leave with a lead, and watch the win evaporate on one swing against a reliever. That uncertainty — outside his control entirely — is what makes 20 wins so difficult to assemble.

Six days’ rest and the 100-pitch limit

Two management systems set the ceiling.

The first is the six-day rotation, standard in Japan and a real difference from MLB, where starters typically work on four days’ rest. Six days limits an NPB starter to roughly 25 starts a season, against about 30 to 33 for an MLB counterpart. Reaching 20 wins from 25 starts requires a winning percentage above .800.

The second is the pitch limit. Removing starters around 100 pitches to protect their arms has made the complete game nearly extinct. Leave with the lead and the outcome belongs to the bullpen.

Fewer innings and fewer starts, together, are what turned 20 wins into the modern wall.

Quality starts versus wins

A quality start — six or more innings, three or fewer earned runs — measures what a starter actually did. Wins do not track it closely.

The reason is the dependency described above. A perfect quality start earns nothing if the offense is shut out, and a strong outing is erased when a reliever surrenders the lead.

Quality starts exist precisely to strip the luck out and evaluate the pitcher’s own work. The predictable result is one of modern baseball’s recurring characters: the unlucky ace, with an excellent quality-start rate and a win total that badly understates him.

Darvish and Tanaka have both cleared 200 across the two leagues. The open question is whether anyone will do it in NPB alone again.

Masanori Ishikawa: 188 wins

Ishikawa is 46 years old, in his 25th season, and has never worn another uniform than Yakult’s.

In 2025 he extended his own NPB record by winning a game in a 24th consecutive season. He now needs 12 more for 200 — and his would be a pure NPB 200, not a combined total.

He is 167 centimeters tall, which has never mattered much. Command, a deep mix of breaking balls and meticulous self-maintenance have kept him on a mound as the league’s oldest active pitcher.

Accumulating wins in your late 40s under a specialized bullpen system is close to impossible. It is a race against time, and Japanese fans are watching it closely.

Takayuki Kishi: 174 wins

Kishi passed 170 wins in 2025 and, at 41, remains a fixture in the Rakuten rotation.

His signature is a curveball that seems to drop from a great height, paired with a four-seamer that appears to rise. The delivery looks effortless, and the command that comes out of it is used as a teaching model for younger pitchers.

Building 174 wins as an ace for two organizations, Seibu and Rakuten, in the specialization era is its own kind of proof. He continues to work in Sendai, the city known in Japan as the City of Trees.

Hideaki Wakui: 170 wins

Wakui has reached 170 wins as of September 2026, on the back of remarkable stamina.

He has pitched for four organizations — Seibu, Lotte, Rakuten and Chunichi — and won games for all of them, which speaks to an unusual ability to adapt. Along the way he won a Sawamura Award, Japan’s Cy Young equivalent, and became the first pitcher to lead the league in wins with three different teams.

Now in his 40s, he holds a rotation spot without having suffered a major injury. He needs 30 more wins for 200 and Meikyukai membership — a steep climb, and one worth watching.
