Lean or Sushi??

It’s time for everyone’s favorite game!!

Lean terms regularly applied in Japan don’t always get translated into English when the concepts are used in the United States. Reasons for this include lacking a concise literal translation from Japanese to English, or the Japanese term is used to preserve the integrity of the topic and an English translation makes it seem a little less authentic. Lean terminology translation does not always capture the essence of what it really means.

Either way, failure to translate can be both confusing and intimidating to non-users or individuals who are first being introduced to the concepts. It can certainly be hard to tell whether a word being used by a Lean practitioner is a Lean term or they are referring to sushi.

How confusing can it be? Take this little “Lean or Sushi?” quiz! (Print out your own quiz copy here!)

For every word, determine if it is referring to a Lean concept or something related to sushi.

Please note: this exercise is not intended to make light of the Japanese language, but rather to demonstrate that it is more important to understand the Lean concept and intent as opposed to proper application and memorization of the Japanese term in a sentence.

1.       Kaikaku is a LEAN term that means “revolutionary change” – it is a monumental shift in how a process is completed, while Kaizen is more gradual and “evolutionary.”

2.       Kazunoko is a SUSHI term for herring roe.


3.       Poka Yoke is a LEAN term for error-proofing a process so that there is only one way – the right way – to complete it and it is impossible to complete incorrectly.

4.       Tempura is a SUSHI term for battered and fried vegetables.

5.       Heijunka is a LEAN term for production level-loading so that peaks and valleys in production are minimized and work can be better standardized.

6.       Hanedashi is a LEAN term referring to machines automatically popping out completed components and setting ready for the operator to load the next one – this saves time for the operators on having to remove the components themselves.

7.       Hokkigai is a SUSHI term meaning surf clam.

8.       Nagara is a LEAN term meaning “while doing something” – for example, an operator could do two things at once like walking while assembling two components for preparation for the next step in the process.

9.       Nigiri is a type of SUSHI with a clump of rice beneath a piece of fish.

10.   Nama-tako is a SUSHI term for raw or fresh octopus.

11.   Hoshin Kanri is a LEAN term for strategic deployment.

12.   Hoisin is a SUSHI term for a sauce used in Chinese cooking, much like barbecue sauce.

13.   Gemba is a LEAN term referring to where the work actually happens. Managers should frequently “go to the gemba” to see for themselves firsthand what is actually occurring in their processes and obtain feedback from process operators.

14.   Genchi Genbutsu is a LEAN term for “go and see for yourself” – much like “going to the gemba” genchi genbutsu refers to going and seeing for oneself what issues might be occurring.

15.   Kim Chee is a SUSHI term for spicy marinated cabbage.

16.   Mizusumashi is a LEAN term for internal material handler running “milk routes” for replenishing supplies and is translated from Japanese as “water spider.”

17.   Mekajiki is a SUSHI term for broadbill swordfish.

18.   Muri is a LEAN term for overworking or overburden in processes. Muri creates excess strain and effort, and ideas should be collected on how to complete such processes with reduced wear and tear on process users.

19.   Kani-kamaboko is a SUSHI term for imitation crab meat.

20.   Kanban is a LEAN term for inventory management and scheduling similar to how supermarket shelves are replenished. Items are pulled from the shelves and replenished based only on what’s taken. Kanban helps prevent overproduction and excess inventory. (Here’s a link to “Personal Kanban” – interesting.)

21.   Koi is a SUSHI term for saltwater carp.

Koi, or saltwater carp, are often kept as ornamental fish and not eaten because of their colorful decorations.

22.   Seiketsu is a LEAN term referring to the fourth S in 5S – Standardize. This is having all operators properly sorting, setting in order, and shining in the same way to promote consistency and similarity across work spaces.

23.   Suzuki, in addition to being a car and motorcycle manufacturer, is a SUSHI term for striped bass or rockfish.

24.   Sumitomo, besides being a brand of vehicle tire, is a SUSHI term for cucumber salad.

25.   Yokoten is a LEAN term for sharing knowledge and learning across an organization.

26.   Unagi is a SUSHI term for freshwater eel. (Ross Geller has a different definition for unagi.)

27.   Muda is a LEAN term for non-value-added activities inherent in processes – reduction and eradication of waste activities is one of the pillars of Lean (along with respect for people).

28.   Ankimo is a SUSHI term for monkfish liver.

Lean or Sushi – QUIZ

Lean or Sushi – ANSWERS

Again, the key point to be made is that the concepts of Lean are more important than the terms we use to describe them. When I was first being introduced to the Lean tools we referred to the process of error-proofing as “error-proofing” and not “poka yoke”, and even today we in the United States don’t use the Japanese terms for 5S such as Seiketsu – we use Sort, Set In Order, Shine, Standardize, and Sustain. It’s important to use terms that won’t be intimidating or unsettling – bringing down any barriers to “changing for the better” must be applied as much as possible.

(Also, while published on April Fools Day this isn’t intended to be a prank, but at least we can have a little laugh about the similarities to the language used in both “industries.”)

Special thanks to Mark Graban and Russell Watkins for helping drive the idea of “Lean or Sushi?” Also, here’s a quick article from Ron Pereira about Lean and sushi converging.
