Samurai From Nowhere aka Dojo Yaburi (1964)
This is standard Samurai movie fare for the 60's but of good quality. I was surprised to find this on YouTube and it's well worth you checking out. The story is well done and covers a lot of various characters. As in most Japanese movies there's a variety of humor, drama, and action.
Ihei Misawa (Isamu Nagato) is an impoverished Ronin with a heart of gold. He rescues a young woman Tae (Shima Iwashita) from being married off to a noble and is trying to find work to pay off boarder guards to get them to the next prefecture and safety. Both of them are living with an alias, hiding out from the authorities.
In addition to hard labor, Ihei is making money by taking on various dojos matches in the area. Fortunately, Ihei is a great swordsman and would like to eventually teach his sword techniques in a dojo of his own. Ihei even competed in a festival match with Gunjuro Ohba (Tetsuro Tanba) but they were too evenly matched. Unfortunately, what money he makes sometimes ends up helping other people where he's staying.
