Interestingly, though the first characters are different, the kanji for “walk” and “beanball” (pitching to intentionally hit the batter) are pronounced the same.

The first kanji in “walk” actually means “four”—four balls equals a walk! Meanwhile, the first kanji in “beanball” is “death.” Perhaps this is why they picked up the katakana version, based on the English “dead ball.”

Example sentences:

(いちろ  にせんよねん  しーずん  にひゃくろくじゅう あんだ  うっしん きろく  たっせい まし)
In the 2004 season, Ichiro set a new record with 262 hits.

(この しあいすずき とうしゅ  こんとろーる うまく いっない しきゅう ばかり だし いる)
Suzuki doesn’t have good control over his pitches in this game. He’s getting nothing but walks.

Japanese Baseball Vocabulary in Idioms

There are some baseball terms that show up in Japanese idioms. Knowing these common ones can help you understand more when you listen and sound more fluent when you speak.

A breaking ball is called a 変化球  (へんかきゅう) in Japanese. 変化球 is sometimes used idiomatically to respond to something that you weren’t expecting (e.g. a proposal or recommendation).

For instance:

(えっへんか きゅう ない )
What? Are you serious? Don’t throw me a curveball like that!

Also from the pitching world, Japanese uses the English word “strike,” only it’s pronounced ストライク (すとらいく). Idiomatically, a ストライク is something that hits a target or is right on the money:

(ことし  なつ  きゃんぺーん  すとらいく )
This year’s summer campaign is right on target.

Finally, although athletes in Japan are generally more low-key and don’t like to gloat, you’ll occasionally see a fist-pump or two when a player comes up big in the clutch.

This is called a ガッツポーズ (がっつぽーず), which comes from the English “guts” and “pose.” Non-athletes will sometimes pull a ガッツポーズ when they do something that goes down well—like a funny joke at the bar, or an idea that gets approved at an informal meeting.

Japan’s Love Affair with Baseball

Baseball has been around in Japan since the late 19th century. Whereas American baseball emphasizes getting big hits at big times, the Japanese style of play is more focused on speed and strategy.

For example, imagine the first batter in an inning gets on base. The next batter will almost always lay down a 送りバント (おくりばんと) — sacrifice bunt (literally “sending bunt”) rather than try to knock the ball over the wall—even if he’s the team’s top slugger!

A major reason for this is (わ). 和 is the spirit of togetherness which is the foundation of Japanese society. Japanese are taught from childhood to prioritize the needs and aims of their group rather than their individual desires. In so doing, they preserve group harmony, and get closer to achieving the group’s goals.

The slugger may really want to go for a home run, but the chances of bringing the runner home are greater if he plays the 送りバント instead. Plus, he doesn’t want to disagree with what his coach says! Hence, he calls up his 和 and lays down the bunt.

Robert Whiting’s excellent book “You Gotta Have Wa” delves into this concept in more detail and also explores the role of 和 in other organizations outside of baseball, such as business companies.

Japanese High School Baseball

In Japan, high school baseball is called 高校野球 (こうこうやきゅう).

Incredibly popular, it rivals the Japanese professional league in popularity during spring and summer tournaments. The high school level tournaments are played at 甲子園球場  (こうしえんきゅうじょう), Hyogo prefecture’s Koshien Stadium, a mecca for baseball fans in Japan.

The 甲子園 tournaments symbolize the purity and fleeting nature of youth for many Japanese, and scenes of players weeping onto each other’s shoulders after striking out are iconic.

Japanese Professional Baseball

Called 日本プロ野球  (にほんぷろやきゅう), or Nippon Professional Baseball (NPB for short), this is the Japanese pro league.

The two halves are the Central League and the Pacific League, which together comprise just 12 teams total. Of them, the 巨人 (きょじん), or the Yomiuri Giants, are by far the richest, most powerful and most popular.

Though the Giants are based in Tokyo, they have fans all over the country, and have provided the backdrop for several household-name dramas, movies and manga, such as 巨人の星  (きょじん  ほし)“The Star of the Giants.”

U.S. Major League Baseball

Major League Baseball (MLB) is メジャー (めじゃー) in Japanese, and it has an immense following in Japan.

Fans particularly enjoy keeping tabs on the Japanese who play in North America. Many feel a sense of kinship and pride in watching players who they saw star in the 甲子園 tournaments grow up to succeed in the big league—and abroad, at that.

Many former international MLB stars have also gone to Japan to play, with some even continuing on to settle in the country. This experience was dramatized (somewhat stereotypically, albeit comically) in the ’90s film “Mr. Baseball.”
