Again, This is the symbol of the Amakusa Jesuit Christians, not Christianity itself. I will tell you what the Japanese think of this group from their perspective. I do not care if you think it's true or not, this is how they're taught the story goes from their perspective.
Also, I would like you to know, yes Japan Persecuted Christians. But you know that book made into a movie Silence ? There's a VERY good reason why it takes place in 1639 after 1638 after this rebellion. A good reason why the Christian persecution became so ridiculously strong in Japan is because of the Shimbara Rebellion.
Roughly, what these Amakusa Jesuit Christian jackasses did was in response to Overtaxation from their local Idiot lord, they took over all the territories in the Shimbara peninsula, conscripted everyone, from children, elderly etc and force converted them to Christianity, then armed these people with guns and forced them to fight the Edo government's army. Knowing the Colonial Jesuits of the time, they likely murdered and persecuted unbelievers among st those they force ably conscripted.

The result was a bloody revolt that was so bloody, the entire population of the Shimbara Peninsula was wiped out. Keep that in mind, from their perspective, essentially every person who had lived in the Shimbara Peninsula had been conscripted and died by these Jesuit nutcases. Oh and Amakusa Jesuits had guns, LOTS of guns from the Portuguese Jesuits who were SO HELPFUL in giving them so many.
You can bet your ass the Japanese weren't pleased with this at the time. They kicked the Portuguese and their hated Jesuits out and then began persecuting Christians to the extreme, particularly hunting and murdering Jesuits to prevent another Shimbaran rebellion.
The Shimbaran Rebellion was also a big reason as to why the Tokugawa slowly tightened their control on Gun usage to absurd levels, hence why so many Edo period shows and Dramas ignore guns.
And btw, the Jesuits of this time period were extremely corrupt. How corrupt? The Portuguese Jesuits used Papal Donations to lease an entire city through "Donations" in the 1570's, much like how they got Macau. The Catholic Church was not pleased, needless to say.
