Takeda Shingen was in the Warring States Period. If you say that this samurai's opponents are all samurai. Then takeda is the most likely.

According to. Most of Takeda's soldiers are wearing red armor. Among them, the cavalry is called the Red Army. The infantry is known as the Hundred Steps Army, with a centipede flag painted on its back. Centipede is the messenger of the Japanese god of war monazite. There is also the flag of Takeda, which is very eye-catching and famous. It is called LAM Raymond Volcano. It means it is as fast as the wind, as quiet as the forest, as fire, as motionless as the mountain. If you see these elements in the movie. That must be Takeda Shingen.

The second possibility, the last samurai. Tom Cruise is so handsome. It's time for Japan to make wise reforms. If you see a musket fight, that's it. In the end, Katsumoto and Tom Cruise fought the Japanese with soldiers, muskets and cannons. Tom Cruise is wearing a red armor. You haven't seen it. I strongly suggest you go and have a look. Super classic.
