Yayoi

Yoshinogari separated residential, ceremonial, productive and funerary enclosures by moats and palisades. This zoning reveals authority, but calling the settlement a 'kingdom' is an interpretation of the park, not a title found in an inscription.

The Wei zhi describes numerous countries of Wa and Himiko as a ruler chosen after disturbances. The text attests to diplomacy and hierarchy in the third century, although it does not unequivocally locate Yamatai.

Most agricultural tools were of wood: hoes, spades and rakes were made with stone or iron blades. Toro preserves this perishable infrastructure that usually disappears from other sites.

Linen and silk textiles, cooking and storage ceramics, wells and large homes extend life beyond warriors and priests. Regional differences prevent designing a single 'Yayoi' costume valid for a thousand years.

The rice paddy is a landscape technology: it combines hydraulic engineering, seeds, calendar and cooperation. Its transfer from the peninsula required adapting varieties and practices to local soils and climates.

Bronze and iron followed different trajectories. Bronze became monumental and ritual in dōtaku, while scarce iron improved edges; stone and wood continued to work alongside both.

Dōtaku with thin walls evolved from sound bells into objects of visual display. Burying thirty-nine together at Kamo Iwakura was a deliberate action, although it is unknown whether it closed, protected or transferred authority.

Himiko is described by a Chinese expression related to spiritual practices. Translating it simply as 'shaman' can obscure the Wei perspective and the combination of ritual, diplomacy and government.

Rice, metal, mirrors, beads and people circulated through the Korea Strait and the Inland Sea. Shared moulds of dōtaku and imported pottery connect communities without the need for a central power directing all exchange.

The embassy of 238–239 turned objects into diplomacy: Wei conferred titles, textiles and mirrors on Himiko. The written list documents the narrated gift, but does not allow us to recognise today which specific specimens arrived.

Red pottery, mirrors, dōtaku and painted vessels built regional repertoires. At Karako-Kagi, fragments with drawn buildings inform how a community imagined its architecture.

Early dōtaku could sound via clapper, but many later ones grew and thinned until privileging visibility. Calling them bells does not guarantee that the thirty-nine at Kamo Iwakura were sounded.
