When Kit first arrived in Tokyo it was to work for an exclusive and very expensive language school that catered to the wives of high-ranking executives expecting to be sent overseas.

The job was well paid and secure in the way that only Japanese jobs back then could be. It was also fantastically boring. Although what finally drove Kit out were the classroom posters, one of which read, Talent requires reformatting what you know. Having identified the Japanese as the world’s first post-modern race, Per Sorenson had created post-modern language tuition, ideally suited to a country where people inevitably told you something by telling you something else.

Kit’s second job paid substantially less but catered to a wider variety of students, one of whom was Mrs. Oniji. It was only later that Kit discovered A1 Language Learning was owned by her husband.

When Kit resigned from A1 it was on the understanding he would continue to give Mrs. Oniji her monthly lesson, and that was ten years ago. She’d been thirty-one and he’d been twenty-five. The arrangement had continued happily until six months earlier, when they’d somehow ended up in bed.

“Are you happy?”

It was unusual for Mrs. Oniji to ask such questions. And the fact she felt able to ask a question quite that personal came as a shock.

“Why?” asked Kit.

“Just wondered,” she said.

Pushing her down, Kit pulled aside the sheet and stilled the hand that came up to cover her breasts. “I’m not unhappy,” he said, positioning himself over her.

Mrs. Oniji sighed. “That makes two of us, I guess…”

Most people when they mention Tokyo mean the twenty-three wards. Metropolitan Tokyo is actually formed of twenty-three wards, twenty-six cities, three towns, one village, and two islands. For Mrs. Oniji the city was smaller still, contained within only three wards: Chiyoda-ku, Chuo-ku, and Minato-ku.

Within these could be found the restaurants of Akasaka, the shopping district of Ginza, and Marunouchi itself, the centre of all things commercial and political. It was in Marunouchi that Kisho Oniji had offices.

Inevitably enough, the restaurant to which she took Kit was in Akasaka, set back behind Hitosuki-dori and separated from the bustle of the street by wooden fencing and a quiet garden. In its courtyard a senior and junior salaryman were finishing one of those clipped conversations that looked—to outsiders—like the verbal equivalent of a punishment beating. Whatever was said, the younger of the two bowed deeply and turned for the exit, standing aside to let Mrs. Oniji pass.

Kit doubted she even noticed.

Walking into the restaurant was like walking into a bamboo grove; dried lengths had been used to divide the low room into waiting area, bar area, and restaurant proper. Not by making walls, because that would be far too obvious, it had been used to suggest where walls might be, as if each upwards stroke of bamboo existed to provide structural supports for a wall that had never been built.

Maybe the lengths were real, or perhaps they were cast from resin. Whatever, the light within each was bright enough to illuminate its skin like neon bars on a cage. There were three dozen such strands, rising from a slate floor and disappearing into the ceiling. The tables were also slate, the chairs wooden. A length of counter was lined with rattan stools, each claimed by someone smart enough to pass muster. The tables might need reservations, but despite complaints Café Ryokan resolutely refused to take reservations for places at the bar.

It was a million miles from Pirate Mary’s in Roppongi, where bozozoku bikers mixed with Western expatriates, Tokyo’s art crowd, and a smattering of Japanese students who believed, sometimes rightly, that they were living dangerously.

“Another sake?”

Kit shrugged, caught himself, and smiled. “Sounds neat…”

The Japanese woman opposite repeated the words to herself and Kit could see her think them through, consider all possible meanings to be found in the phrase, and fail to come up with one that made sense of being offered a drink.

“Slang?”

Nodding, Kit watched her file away the word for later use.

“We should eat,” she said.

Fragments of sea urchin slid across Kit’s bowl, and even black pepper did little to improve their taste, which was over-rich and slimy to the tongue.

This was, he knew, the entire point of eating ezobafun. Its texture being as important as its taste, maybe more important. He could tell himself ezobafun tasted like Mrs. Oniji at the mid point of her cycle, but still his throat tightened with every fresh piece. No amount of sake was enough to wash it down, and he was drinking a lot of sake.

“Slowly,” said Mrs. Oniji. “It is best to eat ezobafun slowly.”

Kit looked up from his bowl.

“Savour it,” she suggested.

He nodded doubtfully.

“You like this place?”

Ordinarily yes, he wanted to say. Only today he was late getting home and Mrs. Oniji and he had at least another three courses to go. The mistake had been in not booking a restaurant himself. Still, Kit understood the compliment she was paying in bringing him here.

“It’s very elegant,” he said. “Very sophisticated.”

“Elegant,” said Mrs. Oniji, turning the word over in her mouth. “Sophisticated.” She got the stress slightly wrong both times and swallowed the middle of her second word, but her English was still infinitely more impressive than Kit’s Japanese, which consisted of five hundred or so words or phrases and could be reduced to the three that mattered.

Domo arigato, Dozo, Sumimasen.

Thank you, Please, I’m sorry.

“There is a difference?”

“Between…?”

He’d been too abrupt. “Let me see,” he said, pushing his bowl aside, while he explained why the arrangement of bamboo in the rock garden outside was elegant while the American woman at the bar was sophisticated. The weather, clothes, food, Impressionist art, and books, these were the things Mrs. Oniji and Kit discussed during their weekly meetings.

“I thought, perhaps,” said Mrs. Oniji, “we could go late-night shopping…” She waited for Kit to nod, his acceptance that this was a good idea. “I need a dress for New York.”

He could hear the simple pride in that sentence. She was flying to America for a week’s holiday, with her sister, her sister-in-law, and her mother. Her husband was too busy to make the trip—Kisho Oniji was always too busy—but his would be the money that paid for first-class flights, the hotel near Central Park, and, quite probably, the presents that all three women would buy him at the Takashimaya department store on New York’s Fifth Avenue.

Standing up, Kit pulled back Mrs. Oniji’s chair. He had been her English tutor for ten years, her friend for three, and her lover only recently. He was not proud of cheating on his wife, but life with Yoshi was infinitely more complicated than most people realised.

Neither Mrs. Oniji nor Kit noticed the man who watched them collect their coats and it would have made little difference if they had. Hiroshi Sato had been selected for the absolute averageness of his looks, height, hair, and complexion.

He was nearly invisible.

Waiting a few seconds, Kisho Oniji’s personal assistant pushed back his stool, dropped a 10,000-yen note onto the counter, and followed the couple outside.
