Japan has a history of Jingoism, but the most severe forms of Jingoism I have ever seen come from Ancient Israel in the Old Testament.
State Shinto is extremely patriotic and nationalistic. The belief is that the Emperor is a descendant of Amaterasu.
To die for the Emperor earns you the highest honors and enshrinement at Yasukuni home of the war dead.

Japan has a history of practically worshipping the ground they walk on, calling their island archipelago the land of the gods, and considering their people Divine, and their land sacred.

That can be a bad thing, but what if every nation were to elect a Shinto Emperor, enshrine every soldier who dies for the country, enshrine and venerate the heroes and builders of the nation, and embrace a highly patriotic nationalism Religion.
As long as they respect other country's sovereignty, I see Jingoism as potentially a good thing.
I love to see passionate fervent warriors who have something to live for, labor for, and die for, and Shinto Jingoism accomplishes that.

Prayer:
Emperor Hirohito,

I consecrate myself to thee for all eternity.
May I never grow weary in serving thee and the soldiers of Yasukuni Shrine.
I am an eternal being, so my prayers may not be answered for up to a thousand years.
Either way, may I for eternity be building you an Empire, the Empire of the rising sun.
May I forever be building Benito Mussolini a Roman Empire for eternity as well, but I am prisoner, POW of Yasukuni Shrine, and the Religion of Japan is my Religion, so Japan is where my loyalty and commitment comes first and foremost.
I offer up all my suffering and prayers and sacrifices for the land of the Kami.
