In the 1970's and 1980's Japanese boxing had a number of notable domestic fighters. Among those was Jackal Maruyama. Here is a short documentary about Maruyama.
We're not totally sure when it was produced, or who by, but for those want to see some behind the scenes training and learn something about the first ever Japanese national Super Featherweight champion this is worth a watch. Even if it's not the most accessible of documentaries.
For those who haven't seen Maruyama fight before we really suggest fans check him out, and his third bout against Tsutomu Itokazu is well worthy of 15 minutes of anyone's time.
Some things don't fit in elsewhere on the site so have been put here as a result.
