It was 8.30pm on a sweaty night in Osaka and I was terrified.
I had just started out on what could only be termed a "men's night out" with a wealthy local businessman who didn't speak a word of English.
My Japanese being non-existent, my stomach churned over the coming hours of empty smiles and general confusion. I feared my partner in crime getting too drunk and passing out because I had no idea where I was staying and all my luggage was at his house.
His English-speaking wife left us to our own devices, and we walked through the bustling streets of the southern Japanese city. Desperate to be accepted, I practised a time-honoured form of communication used by men with absolutely no language or culture or probably anything in common: a series of well-timed grunts of approval for attractive ladies as they walked past. It at least drew a smile from my companion.
But privately, I worried I might be pushing the evening in a direction I wasn't entirely prepared for.
