The short answer: size to your genre, then material and weight
Choose a shamisen bachi (plectrum) in this order: (1) size and shape for your genre → (2) material → (3) weight. The bachi shapes the sound itself, and a mismatched one is not only hard to play but can injure your wrist. Beginners should start with an affordable plastic or wood bachi in the size their genre requires, and move up to ivory or tortoiseshell later.
First, match size and shape to the genre
The bachi’s size and shape follow the neck thickness (thin, medium, or thick). Nagauta (thin neck) uses a small, light bachi; jiuta and folk (medium neck) a medium one; Tsugaru (thick neck) a large, heavy bachi, because Tsugaru is played by striking. If the size is wrong you can’t hold correct form, so don’t compromise here.
Material changes tone and price
| Material | Tone | Price | Best for |
|---|---|---|---|
| Tortoiseshell (bekko) | Deep, soft | High | Performance / advanced |
| Ivory | Bright, clear | High | Advanced |
| Wood | Honest | Affordable | Intermediate / Tsugaru |
| Plastic | Practical | Cheap | Beginners / practice |
Weight affects playability and your wrist
A heavy bachi gives a stronger sound but strains the wrist over long sessions; a light one is easy to handle but may lack power in some genres. Beginners should take the genre’s standard weight as a guide and choose one they can swing without strain. Choosing a weight that spares the wrist is essential to playing for years.
Starting out
A plastic or wood bachi in your genre’s size is plenty to begin with; if your starter set includes one, practise with that. Move up to ivory or tortoiseshell once the instrument and strings are settled and you know the sound you want.
Care
Wipe the bachi with a dry, soft cloth after playing; oils and sweat can discolour natural materials. Keep it out of direct sun, heat, and dryness — tortoiseshell and ivory can crack or warp. If the tip chips or badly frays, replace it rather than playing on, as a damaged tip can harm the skin.
