The Balcony Is Not Outside

My balcony in Tokyo is a metre and a half deep, just enough for one aluminium rail, one geranium nobody chose, and a futon draped over the bar at seven in the morning, still holding the shape of whoever slept under it. It has no chair. It has never needed one.

A balcony here is not a room you sit in, it is a room you use — a machine for airing, not lounging. Every morning is a small negotiation with the sky: futon out if the forecast holds, laundry pinned along the pole if the wind is dry enough, both pulled in fast if a cloud changes its mind. This is called hiboshi, sun-airing, and it is less a chore than a daily audit of whether the day intends to cooperate.

The building code decides more of this than taste does. A Tokyo apartment balcony is required depth, usually just over a metre, because it doubles as an emergency escape route shared with the neighbours on either side — which is why you will find a thin partition panel meant to be kicked through in a fire, and why nobody bolts a permanent table across it. My rail sits at exactly ninety centimetres, high enough to lean a futon on without it slipping, and the whole space cost me nothing extra beyond a pair of outdoor slippers and the geranium, which I have since forgiven for existing.

I have stood on balconies in Copenhagen built for the opposite reason — deep enough for two chairs and a small table, glassed against the wind, furnished the way a room is furnished, meant to be occupied rather than operated. I don't think either country has the truer idea of a balcony. I think one is asking the space to hold a person and the other is asking it to hold the weather, and mine, being smaller, has simply chosen its job.

By six in the evening the futon comes back in, still faintly warm on one side, and I fold it onto the bed before the warmth is gone. This is the only heating I trust completely, and the only one that costs a morning's attention instead of a bill.
