She felt her mother stroking her back over and over, her hand warm through the thin cotton of her blouse. The comfort of it made her feel like crying forever. But eventually her sobs subsided. They stood side by side, gazing out at the rain falling on the hydrangea bushes and the sodden black planks of the fence.

“The whole time I was pregnant with Yoko, I was terrified.” Mrs. Kobayashi’s voice was faraway and musing. “But the second time, when I knew I was pregnant with you, I wasn’t afraid at all. I remember saying to your father when we left the doctor’s office, ‘I’m so happy. I’m really looking forward to having this one.’”

Mrs. Nishimura would treasure these words for years to come.

That night, Mrs. Kobayashi had a recurring nightmare. She was running lost through empty streets, searching in vain for the bomb shelter where everyone else was hiding. The streets were dilapidated, with ghostly forms floating in and out of slatted wooden doorways.

Mr. Kobayashi shook her awake, and as she came to consciousness she heard her own high-pitched moaning. “You were dreaming,” he said.

For a long time afterward, she lay listening to the rain splash against the cement floor of the laundry area. She thought of other nightmares she’d had over the years. More than once she had dreamed Shohei was outside in the night, standing silent in the lane. She couldn’t see him but she knew, as one does in dreams, that he was wearing a white suit like a Cuban musician. In her dream she would scream out, “Take me with you! Please! Don’t leave me here!”

Many times she had woken in the dark and realized, as if her brain was in slow motion, that she had given her child away.

Nighttime reminded her that life, at its core, was fraught with danger.

As soon as Kenji Kobayashi had returned from Manchuria, he had come to the Asaki house with his baby boy. Mrs. Kobayashi avoided his eager, hopeful eyes. She had always known, in a vaguely scornful way, that he carried a secret torch for her. But she felt no respect or admiration. He was a charming ne’er-do-well, a wild card, which appealed to some women but not to her. And he was short. She would never feel safe and protected again, being married to a man no taller than herself.

“Look at the little darling!” cooed Mrs. Asaki, cradling Teinosuke in her arms. “Look, Yo-chan. This is your baby brother.”

They sat down to a simple meal of noodles and broth, garnished with nothing but seven-spice, chopped chives from their garden, and three slices each of hard-boiled egg. “There’s no meat,” said Mrs. Asaki. “I’m sorry…”

“It tastes fine,” her brother insisted. “It tastes like Japan.” His voice choked up a little. “It’s good to be back. It’s so good to be back.”

Mr. Asaki cleared his throat irritably. “You should have worn something else,” he said. “We don’t need a constant reminder of our humiliation.” Everyone looked at Mr. Kobayashi’s belted khaki uniform with its stiff standing collar.

“Yes, sir.” The young man gave a half bow of apology. “Of course.”

They lingered over tea in the parlor. Little Yoko retreated to a corner, where she played quietly with the flat Chinese marbles her uncle had brought her.

Masako, who had been napping in a nest of floor cushions, began to stir. “Here,” said Mrs. Asaki, handing Teinosuke to her sister-in-law. She hurried over to pick up the baby girl, who was parting her tiny mouth in a yawn. “Two babies in the house!” she marveled to the group at the table. “What good fortune!”

Teinosuke was all sharp angles, with none of Masako’s plumpness. His oblong skull was bald but for a layer of fuzz. It was like holding a tiny, querulous old man. Mrs. Kobayashi set him free on the tatami matting and he crawled slowly under the table, like a dying insect.

“How precious!” said Mrs. Asaki. “He’s crawling!” She bounced her daughter-to-be on her lap, and Masako gurgled with joy. Mrs. Kobayashi hated to admit it, but her sister-in-law had a knack with babies. Her own child wouldn’t even miss her when she was gone.

“This is a good cigarette,” said Mr. Asaki, exhaling slowly.

“Have another, sir,” said Mr. Kobayashi. The men inhaled with deep satisfaction as if, now that the war was over, the worst was behind them.

Mrs. Kobayashi felt hysteria rising up within her.

“Yo-chan,” she said quietly, “come sit at the table.” The child came willingly, clutching her marbles in one hand and dragging her floor cushion behind her with the other. She hesitated as she approached, as if sensing the force field of her mother’s emotions.

“Put the cushion here,” said Mrs. Kobayashi, patting the floor beside her.

While everyone continued chatting, she rested her hand on her daughter’s back where no one could see. She ran her hand up and down over the small shoulder blades. The child smiled up at her, with a soft look in her eyes that was exactly like Shohei’s.

Mrs. Kobayashi’s hysteria subsided a little. I can do this, she thought. I’m getting through it, one minute at a time. She forced Masako out of her mind. Over and over she stroked this small person beside her, the only person whom it was safe to love.

Afterward, she and her husband-to-be went for a short stroll to Umeya Shrine. They chatted pleasantly of China ’s history, of people they knew in common, of the crayfish she and Mrs. Asaki had caught in the Kamo River. At one point he cleared his throat. “I know I can’t fill my brother’s shoes,” he said. “But I’ll do my best for you and Yoko.”

“I’m in your debt,” she murmured demurely.

He said nothing about the child she was giving up. For this she was grateful. During their long marriage, it would never come up between them.

Growing up by the sea, Mrs. Kobayashi had heard tales of tsunami as tall as skyscrapers, looming over villages for several moments before crashing. Life’s destructive force, said the grownups with hushed reverence. So heartless, it’s majestic.

That night she lay upstairs in the Asaki house with a sleeping child on either side. There was a faint roaring in her ears. She thought of villagers looking up at a wall of water, a split second before their annihilation.

This new life ahead, this feudal arrangement straight out of history books, had been beyond her ability to imagine. But now, for the first time, she saw how it would be. It would be ordinary. That was the shock of it. They would eat noodles and play with babies and talk about the new restaurant on the west side of town. No one would acknowledge the brutality of it. No one would even notice.

How would she survive? She had no inner resources; she had been rich and pampered all her life. What defined her? Nothing but frivolous memories from her old life. Picnic parties in the mountains with friends from work…the first time Shohei had asked her to tea…one lovely evening when she had glimpsed a star through a hole in her oiled paper umbrella…little Yoko taking her first steps, in a pair of pink kidskin shoes.

Sometimes, if she remembered hard enough, the old romance and possibility and joy bubbled up in her once more like ginger ale.

If this feeling was all she had left, then she would curl her whole being around it. Like a barnacle, she would hold tight while the tsunami crashed over her. I will protect my core, she thought. I will not become a hard, bitter woman.
