Japan doesn't have our constitution.
Our Constitution in no way forbids the government from protecting the citizens. That is the government's primary task.
So you think the Constitution of the United States would allow this:
To start, Japan doesn’t allow the preaching of Islam for conversion. That means no proselytizing or engaging in any behavior that would appear to proselytize Islam.
Japan also limits the number of mosques that Muslims can erect and instructs Muslim men that they should pray at home.
You should try actually reading it if you believe that to be the case.
Here's a good read for you:

To ban Islam you have to remove its status as a religion, which is what the Italians have done.
Italy: Islam Not Recognized as a Religion — Denied Religious Tax Status
Italy has denied religious status to Islam. Politicians cited extremist (fundamentalist) imams, polygamy and failure to uphold women's
rights by Muslim immigrants as obstacles to recognizing Islam as an official
religion in Italy.
And here in the US
we are paying for
extremist imams (like Rauf) and their wives to go on Middle Eastern junkets to raise money for Islamic supremacist Ground Zero mosques. Sick.

Rome, 27 August (AKI) – Mosques in Italy will not receive a share of income tax
revenue the Italian government allocates to religious faiths each year. Hindu
and Buddhist temples, Greek Orthodox churches and Jehovah's Witnesses will be
eligible for the funds, according to a bill approved by the Italian cabinet in
May and still must be approved by parliament.
Until now, the government
had earmarked 8 percent of income tax revenue for Italy's established churches.
The great majority of these funds go to the Catholic Church, although if they
wish, individual tax payers may elect to give the money to charities and
cultural projects instead.
The head of COREIS, one of Italy's largest
Muslim groups, Yahya Pallavicini, said he was bitter that Islam had been denied
the revenue from Italian income tax.
"Work should be begun on legally
recognising those moderate Muslims who have for years shown themselves to be
reliable interlocutors who are free of and fundamentalist ideology," he
said.
Islam is not an established religion in Italy and there is only one
official mosque in the country, Rome's Grand Mosque. Politicians from
the ruling coalition cite radical imams, polygamy and failure to uphold women's
rights by Muslims immigrants as obstacles to recognising Islam as an official
religion in Italy.
Until now, only the Catholic Church, Judaism and other
established churches including Lutherans, Evangelists, Waldensians and 7th-day
Adventists have received the income tax revenue from the Itallain
government.
