Japanese thatched roofs have seemingly been around forever. Japanese thatchers keep thatching. Tourists keep coming. This phenomenon, that I gloss as persistence, is often explained as the prime product of capitalism, religion, or environmental conservation. These reified explanations depart from an individuated subjectivity or sense of agency that arises from within. Instead, this thesis approaches persistence as a matter of emergence - one that is comprised of relations (of relations). I submit that Japanese thatched roofs persist by time bouncing, where people feel their way around their worlds which we are inevitably intertwined with. This approach does not simply capture how one is related to another and crucially foregrounds the very medium of which these relations co-occur (in doing and knowing) in the first place. The stuff of time is the simultaneous - that and as we already are.
