All of those countries are free countries, including religion. Japan even has a pretty cool idea, with what they call freedom of ideology.
Yes and no,
& our societies are very much shaped by their histories,
Japan is it's own case in many respects I'd agree, but not without it's own religious oppression
France
The 1685 revocation of the Edict of Nantes created a state of affairs in France similar to that of virtually every other European country of the period, where only the majority state religion was tolerated. The experiment of religious toleration in Europe was effectively ended for the time being. In practice, the revocation caused France to suffer a brain drain, as it lost a large number of skilled craftsmen, including key designers such as Daniel Marot.
Upon leaving France, Huguenots took with them knowledge of important techniques and production – which had a significant effect on the quality of the silk, plate glass, silversmithing for which the Huguenots were renowned, and cabinet making industries of those regions to which they relocated. Some rulers, such as Frederick Wilhelm of Brandenburg, who issued the Edict of Potsdam, encouraged the Protestants to flee and settle in their countries.

During the French Revolution, the Catholic Church lost its power and influence. The Civil Constitution of the Clergy, passed in 1790, put the Catholic Church under state control.
([Today] most Catholic churches, Protestant temples, and Jewish synagogues are owned by the government. and those using them to worship are subjected to taxes)
Sweden
Liberalization and other faiths[edit]
In order to curb Pietism several Royal Decrees and Acts of Parliament were proclaimed in the 18th century, which forbade Swedish citizens to practice any religion besides mandatory Lutheran Sunday Mass attendance and daily family devotions.
Without the presence of a Lutheran clergyman public religious gatherings were forbidden.
It remained illegal until 1860 for Lutheran Swedes to convert to another confession or religion. From then, and unto 1951, it was legal to leave the Church of Sweden for the purpose of becoming a member of another officially recognised religious denomination. From 1951, it is legal to leave the church, without giving a reason. From 1951 and unto 1977 religious communities (i.e. abbeys, priories, convents and such) were not to be established without the permission of the Crown, but that clause was abolished in 1977.
Also note, that to the extent religious freedom has returned to Russia and China, so has faith & Christianity returned
