Why Does Japan's Conservative LDP Accept Foreign Workers? The Contradiction Between Its Two Support Bases

Recently, while watching the policies on foreign nationals pursued by Japan’s ruling Liberal Democratic Party (LDP), I noticed something rather interesting.

The government is moving to tighten residency controls and crack down more firmly on rule violations by foreign nationals. Yet conservatives continue to criticize it, saying that its measures are too lenient and questioning whether it is genuinely serious about admitting fewer people.

The LDP is supposed to be a conservative party.

So why has it promoted the acceptance of foreign workers?

When you think about it, the reason is not particularly complicated.

The LDP has supporters who want it to limit the acceptance of foreign nationals and supporters who want it to accept more of them.

Conservatives Want to Protect the Country. Business Wants Workers

First, there are ideological conservatives.

These are people who value Japan’s traditions and culture, public safety, and social order.

They worry about changes to local communities caused by a rapid increase in foreign residents, abuse of the system, and cultural friction. They are also cautious about accepting foreign workers.

However, the LDP has another extremely important support base.

The business community.

Its circumstances are entirely different.

Factories, construction sites, nursing care facilities, and restaurants: more and more workplaces cannot secure enough staff with Japanese workers alone.

From an employer’s perspective, the work will not get done if the number of foreign workers is reduced.

In fact, Keidanren, the Japan Business Federation, has also called for the strategic acceptance of foreign talent and the development of the systems needed to support it.

In other words, conservatives say, “Do not let the number rise any further,” while the business community says, “We are short of workers, so let them in.”

They support the same party, yet their demands are exact opposites.

The People Who Profit When the Foreign Population Grows

There are also people whose businesses are built around the acceptance of foreign workers itself.

Companies that recruit workers from overseas, businesses that support employers in accepting them, and various services aimed at foreign residents.

As the number of foreign workers grows, these markets grow as well.

Meanwhile, some economists and policy experts believe that the movement of talent across national borders leads to economic growth.

Their position places priority on addressing labor shortages and improving economic efficiency.

In other words, those who want to promote the acceptance of foreign workers are motivated not only by ideology but also by concrete economic reasons.

While conservatives talk about “Japan’s future,” business owners worry about “next month’s shifts.”

Protecting the future of Japan and keeping a factory running next week operate on entirely different time horizons.

Side with Conservatives, and the Business Community Gets Angry

Seen this way, the difficult position of the LDP becomes clear.

If it drastically reduces the acceptance of foreign workers, conservatives will probably welcome the move. But companies struggling with labor shortages will push back.

Conversely, if it expands acceptance, the business community will welcome the decision, but some conservatives will leave.

In fact, in the 2025 House of Councillors election, Sanseito gained support by campaigning heavily on policies toward foreign nationals, and it also provided a home for conservative voters who had left the LDP.

However, the LDP went on to win a landslide in the 2026 House of Representatives election. Conservative votes have not simply continued flowing away in one direction.

In other words, the LDP must keep conservative voters on its side while also meeting the demands of the business community.

This is where the policy of “continuing to accept foreign workers while tightening oversight” comes in.

It leaves businesses a way to secure workers while allowing the party to tell conservatives that it is strengthening regulation.

Politically, it is quite a rational compromise.

But to people who want the actual number of admissions reduced, it will probably seem inadequate.

Is the LDP a Coalition of Interests Rather Than an Ideological Party?

This brings me to the nature of the LDP as a political party.

It presents itself as a conservative party, but it includes not only ideological conservatives, but also the business community, regional industry groups, and politicians representing a variety of interests.

Each of them has different demands.

The LDP’s strength probably lies in its history of absorbing these different interests into a single party and coordinating among them.

However, that strength is also a weakness.

Whenever it tries to make a decision, someone inside the party is bound to oppose it.

Policy toward foreign nationals is an issue that makes this contradiction especially easy to see.

Conservatives want the party to protect Japanese culture and social order.

The business community wants it to protect Japanese corporate activity.

Both say they want to “protect Japan.”

But one side wants to protect the nature of the country, while the other wants to protect the continuity of business.

And the LDP has to keep both sides happy.

When you think about it, that is an extraordinarily difficult job.

It promises conservatives, “We will protect Japan,” while promising the business community, “We will secure foreign talent.”

It would be impressive if it could achieve both at the same time, but it is hardly surprising that one side or the other ends up dissatisfied.

The LDP is often criticized for not knowing what it wants to do.

But perhaps the reality is the opposite.

It wants to do too many things. Worse, its different supporters want exact opposites.

Under those circumstances, it is only natural that the party cannot reach a unified position.
