"Japan is an impossibly expensive destination for British visitors".

False. Just as prices acquire hitherto-unknown heights when you arrive in Japan so, too, does the concept of generosity.

I was in Japan one Sunday evening, I had no negotiable currency, and there was no way to get from a small provincial airport into town. The distance of four miles was walkable, but in the growing dark only just. Furthermore, the direction signs were (understandably) written entirely in Japanese - a language with which I am not familiar. So I asked for advice in the still-open (but only just) car rental office.

Namizato, the manager, did not hesitate. He grabbed some keys, barked at the office junior and invited me to join him in a top-of-the-range Nissan for the ride into town.

I know his name is Namizato because at the end of the ride he handed me his card with a smile. "Call me if you need any help," he said.

You can easily spend pounds 500 a night for a hotel room in Japan, but a ryokan or minshuki (modest bed-and-breakfasts) cuts this to only pounds 20 or so. Bed was a futon, breakfast was simply rice with a raw egg.

For lunch, I tried a "greasy chop-stick" sort of cafe. Lots of locals were slurping at soup (considered polite) and attacking bowls over-full with food: it was one stab with the chopsticks at the stir-fried noodles, then another at the rice. Sparring with a bowl of each filled me for the rest of the day and most of the evening, and cost a modest pounds 2.50.

The most effective antidote to the humidity of a summer afternoon in Japan is tea. Cafes in markets tend to be the cheapest places to eat and drink, so I subsided into a pokey little place which was situated opposite the fruit vendors and ordered some tea.

The man looked troubled, and said it would take him a few minutes to boil the kettle. The wait was rewarded with a hot, delicately flavoured brew, which I savoured for at least half-an-hour. Only when I came to pay did it become clear that this modest establishment was actually the man's home. It was with immense grace that he declined my offer of few precious yen.
