“My present self is formed almost completely of the people around me. I am currently made up of 30 percent Mrs. Izumi, 30 percent Sugawara, 20 percent the manager, and the rest absorbed from past colleagues such as Sasaki, who left six months ago, and Okasaki, who was our supervisor until a year ago.

My speech is especially infected by everyone around me and is currently a mix of that of Mrs. Izumi and Sugawara. I think the same goes for most people. When some of Sugawara’s band members came into the store recently they all dressed and spoke just like her. After Mrs. Izumi came, Sasaki started sounding just like her when she said, “Good job, see you tomorrow!” Once a woman who had gotten on well with Mrs. Izumi at her previous store came to help out, and she dressed so much like Mrs. Izumi I almost mistook the two. And I probably infect others with the way I speak too. Infecting each other like this is how we maintain ourselves as human is what I think.

Outside work Mrs. Izumi is rather flashy, but she dresses the way normal women in their thirties do, so I take cues from the brand of shoes she wears and the label of the coats in her locker. Once she left her makeup bag lying around in the back room and I took a peek inside and made a note of the cosmetics she uses. People would notice if I copied her exactly, though, so what I do is read blogs by people who wear the same clothes she does and go for the other brands of clothes and kinds of shawls they talk about buying. Mrs. Izumi’s clothes, accessories, and hairstyles always strike me as the model of what a woman in her thirties should be wearing.

As we were chatting in the back room, her gaze suddenly fell on the ballet flats I was wearing. “Oh, those shoes are from that shop in Omotesando, aren’t they? I like that place too. I have some boots from there.” In the back room she speaks in a languid drawl, the end of her words slightly drawn out. I bought these flats after checking the brand name of the shoes she wears for work while she was in the toilet.

“Oh really? Wait do you mean those dark blue ones you wore to the shop before? Those were cute!” I answer, copying Sugawara’s speech pattern, but using a slightly more adult tone. Her speech is a rather excitable staccato, the exact opposite of Mrs. Izumi’s, but mixing the two styles works surprisingly well.

“We’ve got quite similar tastes, haven’t we? I like your bag too,” Mrs. Izumi said with a smile.

It’s only natural that my tastes would match hers since I’m copying her. I’m sure everyone must see me as someone with an age-appropriate bag and a manner of speech that has a perfect sense of distance without being reserved or rude.

A convenience store is a world of sound. From the tinkle of the door chime to the voices of TV celebrities advertising new products over the in-store cable network, to the calls of the store workers, the beeps of the bar code scanner, the rustle of customers picking up items and placing them in baskets, and the clacking of heels walking around the store. It all blends into the convenience store sound that ceaselessly caresses my eardrums.

I hear the faint rattle of a new plastic bottle rolling into place as a customer takes one out of the refrigerator, and look up instantly. A cold drink is often the last item customers take before coming to the checkout till, and my body responds automatically to the sound. I see a woman holding a bottle of mineral water while perusing the desserts and look back down.

As i arrange the display of newly delivered rice balls, my body picks up information from the multitude of sounds around the store. At this time of day, rice balls, sandwiches, and salads are what sell best. Another part-timer, Sugawara, is over at the other side of the store checking off items with a handheld scanner. I continue laying out the pristine, machine-made food neatly on the shelves of the cold display: in the middle I place two rows of the new flavor, spicy cod roe with cream cheese, alongside two rows of the store’s best-selling flavor, tuna mayonnaise, and then I line the less popular dry bonito shavings in soy sauce flavor next to those. Speed is of the essence, and I barely use my head as the rules ingrained in me issue instructions directly to my body.

Alerted by a faint clink of coins I turn and look over at the cash register. It’s a sound I’m sensitive to, since customers who come just to buy cigarettes or a newspaper often jingle coins in their hand or pocket. And yes: as I’d thought, a man with a can of coffee in one hand, the other hand in his pocket, is approaching the till. I quickly move through the store, slide behind the counter, and stand at the ready so as not to keep him waiting.

“Irasshaimasé! Good morning, sir.”

I bow and take the can of coffee he holds out to me.

“Oh, and a pack of Marlboro menthol Lights.”

“Right away, sir.” I take out a pack of the cigarettes and scan the bar code. “Please confirm your age on the touch screen.”

As he does so, I notice him glance at the hot-food cabinet. I could ask him whether he’d like anything else, but when a customer appears to be dithering over whether or not to buy something, I make a point of taking a step back and waiting.

“And a corn dog.”

“Right away, sir. Thank you.”

I disinfect my hands with alcohol, open the hot cabinet, and take out a corn dog.

“Shall I put the hot food and cold drink in separate bags?”

“Oh no, don’t bother. Together’s fine.”

I put the can of coffee, cigarettes, and corn dog into a small-size bag. Until then the man had been jingling the coins in his pocket, but now he suddenly moves his hand to his breast pocket as though something has just occurred to him. Instantly I deduse that he will use electronic money.

“I’ll pay by Suica.”

“Certainly, sir. Please touch your card here.”

I automatically read the customer’s minutest movements and gaze, and my body acts reflexively in response. My ears and eyes are important sensors to catch their every move and desire. Taking the utmost care not to cause the customer any discomfort by observing him or her too closely, I swiftly move my hands according to whatever signals I pick up.

“Your receipt, sir. Tank you for your custom!”

“Thanks,” he says, taking his receipt and leaving.

“I’m sorry to have kept you waiting,” I say with a bow to the woman next in the queue. “Irasshaimasé. Good morning!”

The morning period is passing normally in the brightly lit box of the convenience store, I feel. visible outside the windows, polished free of fingerprints, are the figures of people rushing by. It is the start of another day, the time when the world wakes up and the cogs of society begin to move. I am one of those cogs, going round and round. I have become a functioning part of the world, rotating in the time of day called morning.
