History
Yuasa
In 1909, Shichizaemon Yuasa established Yuasa Iron Works to modernize the family business, founded in 1666 as a charcoal trading business. Yuasa Iron Works began producing storage batteries in 1915, and three years later Yuasa Storage Battery Co., Ltd was established. Soon after, Yuasa Storage Battery Co., Ltd began making Japan's first automotive batteries. In 1925, Yuasa began making dry cells, and in 1941 they began making alkaline cells. The dry battery business was later spun off into Yuasa Dry Battery Co., Ltd, which later merged back into Yuasa Storage Battery Co., Ltd to form Yuasa Battery Co, Ltd, later renamed to Yuasa Corporation.
GS
In 1904, Genzo Shimadzu Jr. (島津 源蔵, Shimazu Genzō; b. 1869 d. 1951) developed a high-capacity lead-acid battery to supply backup power to his factory during outages of Kyoto's then unreliable power grid.
Begin with the source’s own compact description: “GS Yuasa” is company. The dossier treats that line as a proposition to test through Yuasa and company, not as a finished interpretation.
Why this record matters
The phrase “company” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q931156. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1909, 1666, 1915 and 1925.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
