Last night, I successfully identified the individual whose name was inscribed inside the lid of the wooden box. This breakthrough came after I shifted from automated AI searches in samurai registers to the manual examination of Tokugawa family documents available online through museum databases. Every single piece of this jigsaw puzzle is finally complete! I'm excited to share the news with him tomorrow, which happens to be a bank holiday in Japan. Meanwhile, disappointing as it is for someone working in this very field, I can't help but think: what a miserable job the AI did compared to a human eye!
