In the present day, the majority of tombodama (Japanese glass beads) are made using modern equipment such as gas or oil burners and lamps, utilizing pre-made glass. However, when it comes to restoring especially ancient beads, the limitations of using pre-made colored glass become apparent. Shigeki Fujimura's Tombodama Workshop adheres to the traditional methods of the Edo period, as intended by the predecessor, creating colored glass from scratch and finishing the beads entirely with charcoal fire.
