Nigauri

I read Koso Kaku ‘Sakamoto Ryoma Jiten’ (Tokyodoshuppan.)
Koso Kaku says there are many fictitious stories about Ryoma Sakamto.
Many stories referred to the running novel of ‘ Tenkamusojinnketsu Kainandiichikiden Kanketsusenrinokoma.’
It was posted to Sanyo Shinbun at Kochi in Meiji Era. Kaku pointed out several fabricated stories.One of them is this;
though it is said that Ryoma practiced swordsmanship at Edo, it is a false story.
The nigauri has its flowers.
