In today’s information-overloaded society, people’s attention spans are getting shorter and shorter. It seems increasingly difficult to make your audience understand and trust you in a very short time. The renowned Japanese public broadcaster NHK has developed a set of communication techniques known as the “NHK Seven Principles of Credibility.” These principles help newscasters convey facts accurately and quickly within the limited one-minute news broadcast slot, earning viewers’ trust. Whether you are reporting at work, pitching a project, or communicating daily, these seven principles are extremely valuable references. Below is a detailed analysis of these seven principles to help you improve communication efficiency and build trust.
Principle 1: Clarify Your Communication Purpose — Know “Who You Are Speaking To,” “What You Are Saying,” “Why Say It Now,” and “Why You Should Say It”
The first step in communication is to be clear about your purpose. This not only shows respect for your audience but also lays the foundation for earning trust. NHK news anchors must repeatedly consider four key questions before reporting:
- Who is the audience?
You must visualize a specific listener, not speak vaguely. Picture who they are, what they care about, and what information they most need. - What content will you deliver?
Content includes two dimensions: facts and emotions. Facts mean objective data, numbers, event details; emotions mean your attitude, motivation, and emotional connection to the audience. Both are essential—facts alone feel cold, emotions alone may seem hollow. - Why say it now?
This relates to timeliness and urgency. Many important messages aren’t suitable to share at any moment. You must consider why it must be said now and what risks or losses delay might cause. - Why should you say it?
This concerns the speaker’s authority and responsibility. Why should others listen to you instead of someone else? Does your identity, professional background, or personal experience give you this right?
In workplace communication, we often neglect these basic “preconditions,” resulting in scattered topics and listeners unable to catch the point—thus losing trust. Asking and answering these four questions helps communicators clarify information and convey more targeted and persuasive content.
Principle 2: Keep Titles Within 13 Characters — Simple and Attention-Grabbing
Imagine the limited space for text captions below the screen during TV news broadcasts. NHK requires titles to be within 13 characters. Though a technical constraint, it reminds us that titles must be concise and clear in communication.
Why are short titles so important?
- First, attract attention. In an overload of information, a brief, sharp title lets people instantly grasp the core message.
- Second, easy to remember. Short sentences form clear impressions in the mind.
- Third, guide understanding. A proper title acts as a “roadmap,” helping listeners anticipate the topic.
For example: “New Product Saves 5% Costs,” “Lightweight Laptop Launched” — these titles not only convey product highlights but also spark interest and curiosity.
In practical communication, start with a news-like headline. Even in work reports, it helps others quickly understand your core point and want to listen further.
Principle 3: Deliver the Within 15 Seconds to Quickly Capture Attention
In a one-minute news segment, the first 15 seconds are critical. NHK broadcasters deliver the most important news—results, key events—within these first 15 seconds. This “conclusion first, then details” approach helps audiences grasp the main point quickly.
This principle is especially important in workplace communication. For example, when reporting project progress in a meeting, saying right away: “This quarter’s sales grew 10%, exceeding expectations by 5%” grabs attention and trust faster than “introducing background first, then data.”
When stating conclusions, use the journalistic 5W1H principle (When, Where, Who, What, Why, How) for more complete and clear content.
Principle 4: Keep Sentences Under 50 Characters — Use Clear and Concise Language
NHK strictly requires broadcast sentences to be no longer than 50 characters (including kanji, kana, etc.). Long sentences tire listeners and may cause comprehension difficulties.
Concise expressions bring three advantages:
- Easy to understand
Short sentences with clear structure help listeners focus on key points. - Easy to remember
Brief and powerful phrases are easier to store in long-term memory. - Avoid going off-topic
Long sentences often include redundant information and stray from the subject, reducing communication effectiveness.
In workplace communication, avoid complicated and lengthy expressions; learn to package ideas in short sentences for clearer logic.
Principle 5: Support Your Points with Facts and Data to Enhance Credibility
In NHK news reporting, data and facts are the cornerstone of trust. For example, say “Personal consumption grew 5.9% this year,” rather than just “consumption grew.”
Facts reduce subjective assumptions and make communication more authoritative.
However, data alone is not enough. You must translate data into language your audience can easily understand and combine it with emotional appeals, such as:
“This year’s 5.9% growth in personal consumption means a real improvement in people’s living standards and a restoring market confidence.”
This combination helps the audience accept information both rationally and emotionally.
Principle 6: Prepare a Topic Map in Advance to Avoid Losing Your Train of Thought and Boost Confidence
Forgetting lines during news or speeches is common. NHK suggests treating titles and keywords as a “topic map” to constantly remind yourself of the content structure.
When stuck, repeating the title or using simple filler sentences can help you regain your train of thought:
“As mentioned earlier, ‘New Product Saves 5% Costs,’ now I want to explain customer feedback…”
This self-prompt prevents breaks in logic and lets the audience feel your clear thinking and professionalism.
Principle 7: Adjust Your Expression Style to the Audience — Flexibly Use “NHK Style” or “Private Style” Communication
NHK news style emphasizes “quickly and accurately delivering conclusions,” prioritizing trust; private-sector news tends to “build suspense and attract interest.”
In communication, choose your style based on the audience and purpose:
- When needing quick understanding and trust, use “NHK style” — direct, conclusion first, then details.
- When wanting to spark interest and curiosity, adopt “private style” — gradually build the story and set suspense.
Mastering these two styles flexibly helps you navigate various situations with ease.
The “NHK Seven Principles of Credibility” is an efficient communication toolkit honed through long-term news practice. It emphasizes:
- Clear goals — know “who you speak to,” “what to say,” “why say it now,” and “why you say it.”
- Conciseness — titles under 13 characters, sentences under 50 characters.
- Deliver conclusions quickly — capture attention within 15 seconds.
- Balance data, facts, and emotions to strengthen persuasion.
- Prepare thoroughly to avoid losing your way.
- Adjust style flexibly according to the audience.
Whether you are a workplace newcomer, manager, or speaker, practicing these seven principles will significantly enhance your communication efficiency and trustworthiness. Next time you prepare to speak, try to think like an NHK broadcaster: who is listening, what to say, why now, and why you. Lead with a concise title and conclusion, support with facts and emotion, and deliver your points quickly and precisely. You will find your audience’s trust and understanding come faster than you expect.
