Interesting short video clip.
I think it is taken from the Weekly Sunday Fishing Tenkara Masters 1 video.
「テンカラの達人1」 出演、竹株渓遊、天野勝利、石垣尚男
[Tenkara Masters 1] Featuring, Takekabu Keiyū, Katsutoshi Amano, Hisao Ishigaki ]
The video is on YouTube, but not listed by the original video title.
You can find it in this previous forum post:

I have looked at the PARRMARK web pages many times before.
There are several pages about him. He seems to have also used this pen-name:
竹株希朗氏 , Mr. Masaru Takeyoshi, if that is the correct translation.
His casting style is very different from what is mainly seen taught today. From information on that website it is a difficult casting method to learn. His casting method appears to take a lot of energy. Not the 12:00 to 2:00 arc used now.
I could never figure out what ハイループ [hairūpu] means in the description of the lines he used.
Digital translation will translate ハイループ as High Loop.
I thought maybe it was an old line company name. Or a name for a type of line no longer made.
From the PARRMARK web page.
道糸 ：ハイループ4号
ハリス：ハイループ2号
Thanks for the links.
