Toshikazu Kawaguchi's BEFORE THE COFFEE GETS COLD (Tr Geoffrey Trousselot)

How could I spend a January in Japan without giving what seems to be the most popular Japanese novel in recent memory a try? Especially if it's a time travel story?

I mean, the elevator pitch for Before the Coffee Gets Cold, is dead captivating: a dingy little basement cafe's secret to modest success is that it can send you backwards in time, but the duration of the visit is only as long as it takes for a fresh cup of coffee to get cold. There are other restrictions even tighter, but this is the one that's in the cover blurb, indeed, the title; I'm not going to spoil the others except to observe that the usual quandaries of time travel stories don't apply here. You can't change the past from this café. But you can do some very special things if you accept the risk. 

Author Toshikazu Kawaguchi made his bones as a playwright and adapted this novel from a stage play, so there is also a limitation on where things take place. It's all about the cafe. And, still very play-like, most of the meaning is transmitted through dialogue, though some exposition is carried out the old fashioned way, too.

You'd think the results would thus be a bit dull, but they're anything but. For instance, among the stories this scenario lets Kawaguchi tell is one about a pair of regular customers, a husband and wife coping with early onset Alzheimer's. The husband has forgotten the wife completely, but with the help of the cafe and its kind-hearted staff, she discovers a kind of hack he concocted to communicate with her beyond the reach through time his failing memory could otherwise grasp. No, you're the one who's crying. I merely have something in my eye.

Kawaguchi's characters all have to be exceedingly clever to get any utility out of this very limited form of time travel. Watching them figure out ways to work within the limitations is as interesting as seeing the outsized emotional impact of their successes is moving. I can certainly see why this little novel has gotten several sequels. It's simply exquisite.
