I like watching the old men smoke on the Shinkansen, there’s a certain furtive elegance to it. Not quite nonchalance but something akin to devil may care. ‘Nationality doesn’t matter,’ Tanaeda-San says, ‘culture is only the tiniest artefact, it’s a trait that grows over time or is embedded in youth.’ I’m not so sure, I tell him, our elderly carry themselves differently, almost fearfully at times, their retirement seems almost a gamble. ‘So so so so so,’ he says, and turns to watch his country sliding by the cabin window. ‘Then perhaps they need to consider not stopping.’
