Is It Gemba or Genba?

Short answer: It is Genba (現場). But Gemba won. Jim Womack’s Gemba Walks settled the matter for the English-speaking lean world, and I stopped fighting about it around age 50.

The Kanji

現場 is two characters:

• 現 (gen) — actual, present, existing
• 場 (ba) — place, location

Together: “the actual place.” The place where the work happens.

The correct romanization is genba. There is no single consonant “M” in the Japanese language. There is ma, mi, mu, me, and mo — but not a standalone M. There is, however, the confusing “n” (ん) which appears in many words and can sound like “m” to the American ear before certain consonants. That is how genba became gemba.

How Gemba Won

Oddly, the lean community gets this right with other Japanese words that made it into the English vernacular — Genchi Genbutsu, Genjitsu — all correctly romanized with an “n.” But genba sounds like “gemba” to English speakers, and the spelling took over.

Jim Womack published Gemba Walks and it was game over. Consulting companies use Gemba. Books use Gemba. In speech, everyone except Japanese speakers uses the term Gemba. I even named this section of my site “Gemba Coach” out of practical reality.

I wrote about this years ago and swore I would fight it to the death. I lost.

Does It Matter?

Arguing about the romanization of Japanese words is like arguing about Latin pronunciation. As long as you understand the meaning — go to the actual place where the work is done, observe with your own eyes, grasp the facts — I am fine with either spelling.

Sort of. But it is Genba.
