The Story Behind the Words — Iemoto’s Essay —
Iemoto speaks about “lack of sleep”
I’m the Iemoto—the head of ORERYU SOUHONKE. "lack of sleep". These words bring out a person's true feelings, even before the neatly arranged façade. The words I thought I could say, but couldn't, I put into my heart with a little exaggeration. That alone sparks a conversation and makes you and those around you feel a little lighter. That's what's so interesting about “GOROKU T-shirts.“
It's okay to have days to dress up. But in the end, don't hide your feelings and take responsibility for your choices. What's interesting about “Sleep Deprivation“ is that it makes you laugh at first, and then leaves a strange impression on you afterwards. The meaning changes when you look back on your own day, not just someone else's. Including those changes, the story becomes the story of the wearer. That's why "lack of sleep" is not just a word you just read. The clothes you choose in the morning, the conversations you have with your friends, the moments you want to stand out in, and the signals that make today's actions just a little more interesting.

The words I thought I could say, but couldn't, I put into my heart with a little exaggeration. That alone sparks a conversation and makes you and those around you feel a little lighter. That's what's so interesting about “GOROKU T-shirts.“ Even the same word has different meanings depending on the experience of the wearer. That's fine.
A joke has someone to take it from. Look at the place and the person, and don't force yourself on people who can't laugh. It's chic to include that consideration. Be prepared to be laughed at, and don't forget to respect others.
If you're going to give it as a gift, choose someone with whom you can laugh about “lack of sleep.“ Even the time you spend imagining the other person's face becomes part of the gift. Clothing becomes more than just cloth, it becomes a signal between people.
You don't have to force yourself to become a different person on the days when you wear "sleep deprivation." Laugh at yourself, accept who you are now, and walk with dignity. A list of words is a small flag that makes you interesting that day. ― Iemoto, ORERYU SOUHONKE
