Thank you for reading.
Today, I would like to discuss a Japanese workplace practice that may see unusual from a Western perspective: “nommunication” — the tradition of building workplace relationships through after‑work drinking.
■ Introduction
In discussions about Japanese corporate culture, nommunication has long been a topic of debate. For decades, company drinking gatherings have been valued as a way to strengthen team cohesion, yet they are also criticized as outdated and misaligned with modern work styles.
Personally, I am against any drinking event that feels forced. However, from a practical management standpoint, I do believe that well‑designed informal gatherings can play a meaningful role in facilitating smoother communication and decision‑making.
Drawing on my experience as a business leader — and on the differences I have observed between Japanese and Western communication styles — I would like to re‑examine nommunication in a modern context.
1. Nommunication has long functioned as an “informal information channel”
At drinking gatherings, people often share honest thoughts and small concerns that never surface in formal meetings. I have frequently gained insights during such occasions that later informed important management decisions.
Examples include:
Honest opinions that are difficult to express in meetings
Subtle organizational dynamics and atmosphere
Candid feedback from younger employees
Early signs of upcoming opportunities
Small discomforts or unstructured issues that have not yet been verbalized
In Japanese companies, roles are not always clearly defined through job descriptions as they are in Western organizations. Ambiguity is often compensated for through “reading the air” and relational cues. Because of this, informal channels have historically played a significant role in supporting the quality of decision‑making.
2. Differences in communication styles between Japanese and Western companies shape attitudes toward drinking culture
When I worked for a foreign company, a European colleague once told me, “I don’t understand why coworkers go drinking together after work.”
This reaction stems not only from cultural differences, but from fundamentally different communication structures.
● Characteristics of communication in Western companies
Clear job descriptions → roles and responsibilities are defined in writing
Information is exchanged in official meetings → informal channels are unnecessary
Flat hierarchy → no need to drink with one’s boss
Strong respect for personal time → after‑work hours belong entirely to the individual
Psychological safety is ensured through systems → no need to rely on alcohol
● Characteristics of communication in Japanese companies
Flexible role boundaries → many areas cannot be covered by documents alone
“Atmosphere” and relationships influence how work progresses → informal channels matter
Strong hierarchy → honest opinions rarely surface in formal settings
Weak ties support information flow → casual conversations affect work quality
Voices from the frontline often struggle to reach leadership → drinking gatherings become a venue for upward communication
In short, Western companies simply do not need nommunication, which is why the practice often feels foreign to them.
3. Forced drinking is unnecessary — but eliminating it entirely creates “blind spots” in information flow
In today’s compliance‑focused environment, mandatory drinking events are no longer acceptable. Younger generations also value personal time more, and preferences have diversified.
However, completely eliminating informal gatherings can create challenges:
Fewer opportunities for casual conversation
No space for honest opinions
Harder for employees to find the right moment to seek advice
More difficult for leaders to sense organizational temperature
Reduced access to frontline insights
Nommunication has historically functioned not merely as a tradition, but as an information‑supplementing mechanism shaped by Japanese organizational culture.
4. My conclusion as a business leader: drinking gatherings can be valuable — if properly designed
I do not endorse drinking events unconditionally. However, with thoughtful design, they can become a healthy and effective tool for organizational communication.
Key principles for designing modern nommunication:
Participation must be completely voluntary
Small groups enable deeper conversation
Managers should never pressure anyone to drink
Keep the duration reasonable
Respect the values of younger employees
The purpose should be “relationship‑building and information sharing,” not drinking itself
By redefining nommunication as a light, modern form of dialogue — rather than a relic of the past — it can continue to serve as a meaningful and healthy practice.
