Kirin's Boardroom Welcomes 'AI Executive' CoreMate: How 12 Unbiased Personas Are Changing Decision-Making

Hello, wheat-lovers! Thank you for coming to Mugi-ya's note! (´∀｀)

Today, I want to share some news that made me blurt out, 'Wait, seriously!?'

It's about a major Japanese corporation that has officially introduced a management meeting support tool called an 'AI Executive'.

And apparently, it speaks without any sugarcoating...

Isn't that incredible?

'The same people are talking again.' Is your meeting okay?

Can I ask you something honestly?

Have you ever had an experience like this while participating in a meeting?

'I read the room and agreed with my boss even though I thought otherwise.' 'Only the same people ever speak up. So much for diverse opinions...' 'Even though I had a good idea, the atmosphere made it impossible to speak up.'

I've worked in back-office roles handling accounting, legal, and general affairs, and meetings are truly difficult.

Especially when it comes to topics close to management, everyone reads the room, and it ends with a vague sense of 'consensus...'

But in this day and age, that's dangerous.

The business environment has become too complex, and 'human-only judgment' is reaching its limits.

According to an April 2026 article in Forbes JAPAN, the environment surrounding companies is becoming increasingly complex due to geopolitical risks, inflation, and rapid market changes.

Mitsuharu Yamagata, Managing Executive Officer in charge of Digital and Information Strategy at Kirin Holdings, says this:

'It is becoming difficult to make good decisions with diverse perspectives using only the methods of the past.'

I don't think this is just a story for large corporations.

Even when creating content as a side hustle or trying to utilize AI, have you ever felt that information is exploding and you can't keep up with the decision-making?

I definitely have.

That's exactly why I thought Kirin HD's initiative was 'the real deal'.

An "AI executive with no bias" has appeared in management meetings.

Since July 2025, Kirin Holdings has fully integrated "AI Executive CoreMate" into its group management strategy meetings.

According to an article in Forbes JAPAN, this is a management meeting support tool independently developed by Kirin HD.

Its most notable feature is that it has been given 12 distinct personas.

• "A persona cautious about risk management"

• "A persona proactive about innovation"

• "A persona that prioritizes long-term perspectives"

...and so on, it seems to provide opinions from 12 different professional viewpoints!

Isn't that amazing?! (´∀｀)

Furthermore, this AI has ingested the past 10 years of minutes from board meetings and group management strategy meetings, internal key documents, and the latest external information to build these 12 personas.

It is truly an AI that can deeply reference Kirin's past discussions and internal context.

In actual management strategy meetings, CoreMate participates by posing questions in response to proposals or statements made by executives.

For example, comments like "How will you measure the non-financial impact of this initiative?" are displayed on a monitor, and someone shares them with the room by saying, "We have this opinion from the AI executive."

They say it really stimulates discussion!

"I honestly felt anxious that my reason for being might be halved"

What's interesting here is how the executives received the AI.

Looking back at the initial implementation, Mr. Yamagata says this:

"Although they didn't say it out loud, I think some executives felt a vague anxiety that 'my reason for being might be halved.'"

I thought this was a very honest comment.

The anxiety about incorporating AI into one's work is something that everyone feels the same way about, whether you are an executive, a regular employee, or a side-hustle writer like Mugi...

However, Mr. Yamagata continues as follows.

Instead of drawing up a perfect blueprint before moving, the shortest path is to improve accuracy while in motion.

These words really hit home for me.

When I first started using AI, I was initially nervous, thinking, 'Will I be able to use it properly?' or 'What if I fail?'

But there are definitely things you only understand once you actually try using it.

A 'brainstorming habit with AI' that even individuals can start today

In the article, Mr. Yamagata mentioned that he feels it is 'particularly effective' forbrainstorming during the meeting preparation stage.

This is incredibly useful even at an individual level!

I personally brainstorm outlines with Claude before writing articles, and when I'm stuck on ideas, I ask, 'What do you think about this perspective?' which has been a huge help.

It's a waste to use AI only as a 'search tool'!

I believe the smart way to use AI from now on is to use it asa 'dialogue partner with diverse perspectives'.

Just as a large corporation prepared 12 personas, if we also assign roles to AI, such as 'Try thinking from a risk perspective today' or 'What about from a long-term view?', we can gain unexpected insights♪

Summary: AI is starting to change management as a 'colleague that doesn't sugarcoat things'

To summarize what Kirin HD's AI executive CoreMate taught us:

✅ AI can bring 'diverse perspectives' to meetings ✅ A 'learning while moving' attitude is more important than a 'perfect blueprint' ✅ Even at an individual level, just using AI for 'brainstorming' improves quality ✅ At least in the case of Kirin HD, AI is positioned not as a replacement for humans, but as a partner for decision support

The era where large corporations seriously incorporate AI into management has arrived.

I think that means for those of us working as individuals or on side projects, whether or not we can properly use AI will become a major differentiator in the future.
