120mm Honenuki Azumagata (Round Fish Bone Tweezer)

Tweezers in Japan are referred to as Kanto or Kansai style. These terms refer to two different regions of Japan (Tokyo is in Kanto while Kyoto and Osaka are in Kansai). Historically, the Kanto region consumed more fish with tender flesh so the rounded tweezers were more practical. In the Kansai region, however, more firm-fleshed fish were consumed, which required tweezers that could reach deeper to pull out the bones.

The Kansai-style tweezers, known as the Honenuki Azumagata or round tweezers, are suited to removing smaller bones or pin boning.
