As scientific archaeology takes hold in Japan, our understanding of the nat
ure and content of Japanese prehistory is changing radically. All of the pe
riod boundaries of Japanese prehistory are being rewritten, and many new 'a
rchaeologies' are growing up around particular scientific techniques. New p
ublications in English give greater access to archaeological thinking in Ja
pan, while Japanese publications focus on ever-narrowing aspects of prehist
oric lifeways. Policy changes are giving archaeologists more access to the
imperial tombs, and rescue teams are under less obligation to 'save everyth
ing' as selective preservation is instituted.
