The end of
“only they can do it.”

AI turns that work into something anyone can do.

“The day they quit, everything stops.”

That's alright. There's still time.

When work depends on one person, the business stops

Over half of the Japanese companies
that closed down in 2024 were profitable.

According to Japan's SME Agency (2025 White Paper), 51.1% of companies that voluntarily closed or dissolved in 2024 were in the black. They didn't fail. But when judgment and know-how live only in one person's head, no one can take over, and a healthy business quietly disappears. DBA Japan provides corporate AI training that puts an end to “only they can do it.”

59.5%

Only one person
knows how to teach the work

In a Japanese government survey, the most common problem in workforce development was “not enough people who can teach” (59.5%), followed by “people leave after we train them” (54.7%).
When teaching depends on one person, training stops the day that person is away.

441

One resignation stopped the whole company

In FY2025, 441 Japanese companies went bankrupt due to labor shortages, the highest on record. 118 of those were triggered by the resignation of employees or key managers, also a record.
When work belongs to one person, losing that person is a business risk.

87%

They adopted AI, and nothing changed

In PwC's five-country survey (2025), Japanese companies that felt AI exceeded expectations: just 13%.
If work still depends on that one person, AI alone changes nothing. It's not a tool problem. It's how work is handed over.

FAQ

Frequently Asked Questions

What does “the end of only they can do it” mean?

It means taking the know-how and judgment that live only in one person's head (tacit knowledge) and, with AI, turning them into a form anyone on the team can use. In the training we work on your real tasks, down to handover, onboarding, and manuals, so quality holds even when that person is away or leaves.

How is the program length decided?

It depends on the course. The Intensive course runs about two months (20 hours), the Practical course about four months (22 hours), and the Foundation course about two months (10 hours). All meet the subsidy requirement of at least 10 hours.

Can the program be tailored
to my company?

Within the package, we tailor it to you, moving from workflow interviews into exercises that use your own real tasks. Fully bespoke development is not allowed under the subsidy rules, but in practice the content ties directly to your daily work.

Is the subsidy guaranteed?

It depends on requirements such as the subsidy program's ten labor management criteria. A certified social insurance and labor consultant runs a preliminary assessment. When the requirements are met, the approval rate over the past two years has been high, based on the consultant's record.

What is the minimum number of participants?

We can run it for a single participant, though the subsidy benefit is greatest with two or three people (up to 300,000 yen per person).

Can we take part from outside Tokyo?

Yes. Combining online and in-person sessions, we deliver nationwide, with experience at a ryokan on Sado Island.

When is payment due?

A 50% deposit, with the balance paid in installments. The subsidy is disbursed about six months after training ends, the standard lead time set by the Ministry of Health, Labour and Welfare.

Can the training be delivered in English?

Yes. Our representative holds Eiken Grade 1 (the highest level of Japan's national English proficiency test) and lived in the United States for five and a half years, so training and materials can be delivered in English.
