Is frequently breaking the ichi no ito common?

Hi, this is my first time posting on here :slight_smile:

I’ve been playing shamisen for almost two years now and recently I’ve been noticing that my ichi no ito has been breaking more often. Is that normal?
I’ve gone through three of them in the past six or so weeks and I’m wondering if is there any way I can prevent them from breaking as often?

Just to confirm, your ichi-no-ito is the thickest string, right?

If that’s the case, then it’s off for it to be breaking so rapidly. Ichi-no-ito have the most robust construction and are generally used the least in typically playing.

Check that your bachi and koma haven’t acquired a sharpened edge due to use.
