Mio Yamada has a deep voice with a reassuringly matter-of-fact quality about it. She tells me that her day, like every day in Rwanda, is going to be spent troubleshooting. This is mostly what life is about for her at the moment: dealing with electricity blackouts, water getting cut off ...This affects her business, running Kiseki, Rwanda's first Japanese restaurant, but it's also just everyday life.

"How to solve problems is always the main topic of the day" she says, when I ask what it's like for her living in the Central African country.

"It's completely different from Japan; you wouldn't have these issues unless there's been a huge disaster like an earthquake or a typhoon," she says. "Everyday here is like (there's just been) a big earthquake or typhoon, but I've already got used to it."
