Less than a month before my family wrapped up our time in Japan last June, Tim Wolput of Lean Japan Study Tours invited me to join him on a day-long gemba visit to two different lean thinking Japanese organizations in Tokyo â a local government ward office and dry cleaner.
I was particularly excited to go and see how kaizen principles were being applied in the government sector, as had visited many manufacturing organizations in Japan that Japan had adopted Toyota-inspired principles and management approaches, but hadn’t seen many examples in other industries.
I had discovered during the prior 17 months that Lean practices are less common in non-manufacturing sectors such as hospitals and that Japanese thinking is not synonymous with Lean thinking.
You can read about my experiences visiting many Japanese organizations in the category “Gemba/Site Visits”.
I managed to sneak in the trip the day before the movers came to our apartment to pack up our belongings and furniture, four days prior to our final exit from Tokyo as official residents of Japan!
I couldn’t pass up this opportunity to go to the gemba – especially for an intimate tour (there were just four of us) and time to talk with their leaders!
Pulling my kanban of Japan-related topics forward
Iâve been meaning to write about these visits for ten months â and I am especially focused writing about these visits and clear out my âbacklogâ of gemba visits to Japanese organizations, as I will be going back to Japan next month.
I have several interesting meetings and site visits lined up – including catching up with Tim, Mrs. Ogura of Ogura Metal and my co-host to Ashikaga, and of course my friend Mr. Isao Yoshino, and will be adding to my ever-growing personal kanban “waiting” queue!
There was so much to learn in these visits that I’ve separated my reflections and observations into several blog posts.
Kaizen, Kaikaku and and Customer Service in Japanese government

Our first stop on that June morening last year was to the Nakano Ward “city hall”. Nakano City (Nakano-ku in Japanese) is one of 23 wards or districts within the broader Tokyo metropolitan area.
It was inspiring to learn how a government bureaucracy is focused on delivering excellent customer service (omotenashi) thorough developing their people and creating an environment where improvement ideas are not only supported, but celebrated.
Our host for the visit was Mr. Nagata, who serves as the Councilor of their internal improvement group, called the Kaikaku Department (read on to learn about the history of the department’s name).

This post is based on what I learned from Mr. Nagata and his colleagues, and from Timâs explanations and commentary.
Nakano’s goals: Develop people to deliver customer value and satisfaction
The number one focus for Nakano City government is âomotonashiâ (the concept of Japanese hospitality).
The government’s main goals are to:
- Improve the satisfaction of Nakano residents / constituents by delivering excellent customer service
- Improve the satisfaction of Nakano-ku employees
- Improve the effectiveness and efficiency of city hall
Mr. Nagata explained that the ward delivers on its goals is by developing people to work self-reliantly to improve the satisfaction of constituents. In order for employees to âgive great satisfactionâ to constituents, employees must enjoy what they are doing!
History of kaizen and omotonashi in Nakano Ward

Tim and Mr. Nakano explained that thirteen years ago, local governments in Japan were in a âbad positionâ and experiencing the same economic crisis that was happening across Japan.
This was the same economic downturn that caused the Japanese town of Ashikgaga to seek a way to “revitalize” their city and their people through the use of 5S and other Toyota Production System (TPS) principles.
The Mayor of Nakano was passionate about omotonashi and for the government to deliver excellent customer service to the ward constituents.
He had some awareness of TPS and kaizen and wanted Nakano to develop itâs own unique version of TPS as a way to achieve their goal of excellent service.

Nakano City’s approachs to improvement
Mr. Nagata spent some time showing us slides and talking to us about how Nakano City Ward approaches improvement.
PDCA
He described PDCA as the foundation of Nakano’s problem solving approach. When talking about PDCA, he highlighted these points:
- First, develop an awareness of the problem (âkizukiâ). This can either be acknowledging problems that everyone sees easily or can be good ideas for problems that many might not even realize exist.
-
The Nakano Ward leadership structure is an inverted pyramid, with frontline employees being the power of improvement and omotonashi. The goal of using PDCA is to make an atmosphere where employees can easily bring forward their ideas for improvement.
- Find the root cause of the problem.
- Experiment with a simple solution and âsmall stepsâ. Donât make a solution too difficult â keep it simple and first see if it works. Itâs okay if itâs not perfect right away.
- Checking is the most important step! Understand why something worked or didnât work.
- Success isnât the primary focus â it is about learning and continuous improvement. Ultimately it is by learning that the workplace is revitalized and employees feel happy.
Side note:Â I found it interesting that at Nakano City Ward, as well as other organizations that I’ve visited such as this Tokyo hospital, use the Roman characters for P – D – C – A, not Japanese characters. This same phenomenon can be seen in advertisements and billboards throughout Japan. I’ve been told that using the Roman characters are used to highlight or call out special words or concepts.

“Chokoto Kaizen” – small improvements – bottom up
Kaizen are small, incremental improvements that are usually bottoms up.
These are the improvements that can be suggested and tested daily during the 5 minute stand-up meetings that are held by each area manager in Nakano City Ward.
Our hosts referred these types of improvement as “chokoto kaizen”. “Chokoto” is slang or informal way of saying the Japanese word for little “chotto”.
Making kaizen suggestions
Nakano Ward has a process for employees to submit improvement ideas (though they didn’t describe it in detail).

Officially about 70-100 ideas are submitted each year, though Mr. Nagata said that many are âjust doneâ and not submitted or tracked through the Kaikaku Department. Managers just support their staff in making the small changes.
Everyday kaizen is the key to Japanese improvement efforts
This is the first time that I had heard the term âchokotoâ in reference to kaizen (although it is also possible that my Japanese wasnât attuned enough on earlier gemba visits to hear it).
However, the importance of small, daily improvements done by everyone from the frontline to senior leaders was a consistent theme across all lean-minded organizations that I’ve visited in Japan – from Toyota Memorial Hospital to a company that manufactures equipment for electricians.

Kaikaku – large strategic improvements – top down
Kaikaku are larger, breakthrough changes that start with a top-down goal that is then broken down into smaller parts.
Groups of employees work together to develop more innovated creative tests of change.
Connection between Kaizen and Kaikaku
Nakano Ward leaders believe that Kaizen and kaikaku are both important. They supplement and complement each other.
No matter what, they explained that it is important to have a goal from the top first to provide direction (this sounds like hoshin kanri â or strategy deployment â to me). Without a goal, even small “chokoto” kaizen can be done in too many directions and isnât focused.
Shifting the focus from small change to breakthroughs
For the first thirteen years of their omotonashi improvement efforts, Nakano Ward focused their energy on chokoto kaizen.
Recently, the leaders found that the mindset for kaizen had been anchored within employees, but that innovation for bigger breakthroughs was not happening often.
The Mayor decided to change the name of the Kaizen Department to the Kaikaku Department to increase staff’s awareness that improvement is not just gradual small change, but also can be bigger ideas.

Celebrating improvement
Nakano Ward believes that celebrating their staff’s improvement efforts is important for engagement. They do this in several different ways.
Kaizen Newsletter
Nakano publishes a public relations newsletter every two months about improvement in the ward office.
The goal is to share ideas across the organization and celebrate the improvement efforts in a âlight and funâ way.

Omotonashi kaizen tournament
At the beginning of each year, all sections in the government office compete for the best kaizen event or idea.
The photos here are from the newsletter highlighting the 2016 omotonashi kaizen competition that was held a few months prior to my visit.
Other ways to celebrate and learn
All division managers get management training and are encouraged to participate in study groups to support their interests and ongoing learning.
Next up – Examples of Kaizen and Kaikaku in action
After talking with the leaders of the Kaikaku Department, we got to tour two floors of the Ward and talk with the area managers.
In my next post, I’ll share these examples of chokoto kaizen and kaikaki improvements and how they have delivered greater levels of omotonashi (customer service) to Nakano Ward Constituents.
