Jlpt N1 Old Question -

He never sent it.

He addressed it to the old cram school’s address, knowing it would return as undeliverable. He sealed the envelope. Then he walked to the post office, bought a stamp, and dropped it into the red mailbox.

Twenty-five years ago, Kenji was a scholarship student at a second-rate university in Tokyo. His father had lost his job, and his mother’s small illness had become a large debt. With tuition overdue and eviction looming, he had done something shameful: he had stolen the enrollment fees from the petty cash box of the part-time cram school where he taught.

The Unpaid Debt

Kenji shuffled through the cardboard box in his closet, the scent of mothballs and forgotten time wafting up. He was looking for an old savings account passbook. Instead, his fingers brushed against a creased, yellowed envelope. On the front, in fading ink, was a single word: “Sensei.”

Kenji turned and walked home. For the first time in twenty-five years, he did not feel the weight of a card in his pocket. He only felt the quiet, bitter grace of a letter that would never arrive.

He took out a pen. Slowly, deliberately, he wrote on the blank postcard: jlpt n1 old question

August 12, 2023. ¥600,000.

Why? That was the question that haunted him as he held the envelope now, retired, his daughter grown. At first, it was poverty. Then, pride—he wanted to send ¥500,000, to prove he was more than his mistake. Then, the shame of the delay itself. Each passing year made the blank card heavier. A postcard that should have taken a year became a decade. A decade became a lifetime.

Sensei paid back the missing money from his own pension. He gave Kenji a receipt for the amount, and a blank postcard. "When you can repay the debt," he said, "write the date and the amount on this card. Then send it. Not before." He never sent it

He was caught the next day. The police were called. He was 22, his future reduced to a single, crushing sentence.

Then the owner, an elderly man named Mr. Yamamoto—whom everyone called Sensei —had dismissed the police. He had looked at Kenji, not with anger, but with a tired disappointment that was far worse. "You taught my students kanji," Sensei had said quietly. "You taught them that 'trust' is written with the radical for 'person' and the word for 'speech.' And yet, you chose to erase the person from your own word."
