September

The moon when scattered things return to their original places. Water vapor becomes dew, day and night become equal in length, and people gather in their hometowns.

In September 2026, the structure of this regression is revealed particularly clearly. On the 8th, White Dew (白露The first dew forms on ), and on the 23rd, the autumnal equinox (秋分Day and night become equal on the 25th, and the Chuseok full moon rises two days later. The full moon closest to the autumnal equinox is called the Harvest Moon in the West, and this year's Chuseok moon is exactly that moon. It is an unusual arrangement where the roundest moon rises over a balanced position.

Scenes of September

Emotional Arc

City vs. Nature

September in the City	Nature's September
The first day of turning off the air conditioner and opening the windows, the office temperature debate ends.	Mist settles over the rice paddies at dawn, and dew forms on the spiderwebs.
The department store basement builds a wall of gift set boxes.	The rice plants change color day by day and bow their heads.
On the Friday right before the holiday, the roads get jammed red starting at 3 p.m.	The riverside silver grass bends down all at once in the direction of the wind.
When the holidays begin, the entire city center empties out and the alleys become quiet.	Only leafless red spider lilies are growing in the temple courtyard.
The number of people wearing light coats on the first subway train is increasing.	A formation of wild geese draws a line across the sky as it passes by.
The planner and diary display stands are coming back to the front.	A split chestnut burr has fallen under the chestnut tree.

Day vs. Night

September of the Day	September of the Night
With the humidity gone, even the distant mountain ridges are clearly visible.	The sound of grasshoppers becomes denser, and the sound of cicadas disappears completely.
The light enters lower than in summer, making the shadows longer.	If you sleep with the window open, you end up pulling the blanket over yourself at dawn.
The strong complementary contrast between rice and sky, gold and cobalt	Double lighting where orange streetlights and blue moonlight mingle
You sweat but it dries quickly, and it is cool in the shade.	The full moon rises unusually large and low.
The best temperature for a nap lasts for a few days.	A night when I end up making a phone call while looking at the moon on the veranda

Usage Concept

Design Concept

style	Concept name	Key elements	palette
Classic	Hangawi table setting	White porcelain and brassware, vertical Mingjo font, a page with large whitespace. The silhouette of the moon jar simplified into a geometric shape.	Rice Gold · White Porcelain Gray · Black
Modern and minimal	Equinox line	A 5:5 split layout that faithfully captures the day/night ratio of the autumnal equinox. A single sans-serif type, with a single circle as the only graphic.	Cobalt · Off-White · Indigo
romantic	Door pairing	Circular composition using the full moon as an object, soft gradation and halation, cursive handwriting	Harvest Moon · Misty Rose · Early Evening Nam Bora

Local Crafts	Harvesting and fermentation	Rough kraft paper texture, pressed text with a letterpress feel, hand-drawn grain illustration	Straw beige · crimson · dark green

Video concept

title	One-sentence concept
Until the dew forms	It captures a single blade of grass with a fixed angle throughout the dawn, showing only the process of water droplets forming, growing, and falling.
Empty city	We photograph the same intersection at the same time every day during the four-day holiday to compare the speed at which people leave and refill.
The person setting the table	The face never appears, and only the hands, bowls, cutting board, and fire follow.
Ten days of color transition	I photograph the same rice paddy at intervals for ten days and stitch together only the sections where the green turns golden.
On the way back	It captures the return journey, not the journey home. Food containers loaded into the trunk and the house receding through the rear window.
Same month, different window	On the same night in Korea, China, and Japan, the same full moon hanging on different window frames is joined together.

Branding Concept

Brand Type	September Campaign Direction
Beauty	Treat this as a rejuvenation season to repair the UV damage accumulated during the summer. Rather than harsh exfoliation, we suggest a layering routine focused on soothing, moisturizing, and coping with daily temperature fluctuations.
Food & Beverage	Putting the narrative of the “first harvest of the year” of fresh grains and fruits front and center. Separating gift demand from everyday consumption, the company operates both a premium line and small-package options for home use.
fashion	The month to decide on your first outerwear purchase. A double styling proposal that captures the temperature difference between midday and dawn directly in the lookbook composition.
Living & Interior	The season for opening windows. Approaching the theme of a “home with longer nights” by combining bedding replacement and lighting color temperature adjustment.
Travel & Leisure	Two main pillars: dispersed travel before and after holidays and day trips to nearby areas. Emphasizes a “less crowded September” that is one step ahead of the autumn foliage forecast.
Finance and Insurance	The starting point for reviewing the second half of the year and preparing for the year-end tax settlement. The concept of balance at the autumnal equinox can be translated into an asset allocation message.
mainstream	The opening of the Oktoberfest season overlaps with the demand for Chuseok gifts. We are operating both a festive casual line and a premium line for holiday gifts simultaneously.
Education and self-development	The second semester and the second half of the year begin together. If you frame it as a "second start" rather than the New Year, you can encourage a fresh start without feeling burdened.

Writing Concept

title	One-sentence concept
Where does the dew come from?	I superimpose the process of water vapor taking shape as the air cools overnight onto the process of a person recognizing emotions.
Two autumn starts	With a 22-day gap between meteorological and astronomical autumn, we follow why there are multiple criteria for defining seasons.
The moon two days after the autumnal equinox	I use astronomy to explain why the Chuseok moon in 2026 coincided with the Harvest Moon, and write about why this coincidence is beautiful.
People who don't go back	It calmly records the September of those who chose not to go to their hometowns for the holidays.
Geography on the top	Tracing the origins of the ingredients for the ancestral rite table, I draw a map of the September harvest on the Korean Peninsula.
The ninth sign of the seventh month	It explains why September remained out of order with its name through the history of calendar revisions.
