Episode #18: How To Kill Your Brand With Public Speaking

Why do smart professionals still give bad presentations?

Even capable leaders sometimes sabotage their own messages because their slides are overloaded and their delivery is misaligned with how audiences absorb information. In Japan, where executive audiences expect clarity, structure, and respect for time, messy visuals and screen-reading can instantly weaken credibility.
Mini-summary: Presentation failure usually comes from preventable basics—slide design and speaker behavior, not content quality.

When presenters treat slides as the main event, they bury the audience in detail and force people to read instead of listen. In a real case, a highly fluent non-native English speaker with a world-class résumé still failed to persuade because the slide deck dominated the talk.
Slides that are dense, multi-colored, and filled with data turn your audience into analysts, not believers. If they need more than two seconds to “get it,” the slide is too complex.
Mini-summary: Slides should support your narrative, not compete with it.

How should executives design slides for clarity and persuasion?

Use zen-like simplicity. “Zen-like” means visual calm, not minimal thinking. Here’s what works:

• One idea per slide.

• Two main colors only, for contrast and focus.

• Remove anything nonessential. If a slide is unclear in two seconds, cut again.

• Favor white space and strong headlines over decoration.

This is especially important for audiences in 日本企業 (Japanese companies) and 外資系企業 (multinational companies) where decision-makers value quick comprehension.
Mini-summary: Simpler slides dramatically increase message retention and trust.

How can you use graphs without killing your story?

Graphs should be visual background, not a data dump. Many presenters overload charts to prove everything at once—long timelines, multiple comparisons, too many labels. That produces confusion, not conviction.

Better approach:

1. Show the full graph as context.

2. Then isolate the turning point on a separate slide.

3. Add a pop-up style highlight with one huge key number.

Your audience remembers the story you pull out, not the clutter you put in.
Mini-summary: Use graphs to guide attention to one proof point at a time.

What delivery mistakes instantly destroy audience engagement?

Two habits ruin even strong content:

1. Standing in front of the monitor and reading slides with your back to the audience.

2. Accepting dim lights that help the screen but hide the audience.

Instead:

• Stand audience-left of the screen so listeners see you first, then the slide (left-to-right reading).

• Face the audience and speak to them, not the monitor.

• Keep lights up so you can read reactions and adjust in real time.

These are basics of プレゼンテーション研修 (presentation training) and are essential for competing in high-stakes executive settings.
Mini-summary: Great delivery is about connection—eye contact, positioning, and visibility.

• Make yourself, not the slides, the centerpiece.

• Don’t bombard people with multi-colored visuals—design for zen clarity.

• Don’t stack graphs—two max per slide.

• Stand audience-left, facing the audience.

• Keep the lights up so you can see and be seen.
  Mini-summary: These five moves prevent “persuasion suicide” and lift executive impact immediately.

• Simple, single-idea slides make your message easy to remember and hard to resist.

• Graphs should highlight one proof point at a time, not everything at once.

• Delivery matters as much as content: face the audience, control your position, keep lights up.
