A takeaway system for a small chain of teishoku restaurants in Sendai, covering a bowl, a bottle, a box, a bag and the paperwork that goes with them.
The chain had accumulated eleven kinds of packaging over fifteen years, all branded, none related. Aoba Packaging Studio replaced the lot with one device: a paper belly band in indigo, wide enough to carry across a lid or a handle, closed with an ochre diamond seal.
The band does the work of a logo. On the moulded pulp bowl it runs over the lid and under the base, holding the closure shut without adhesive and giving the customer a visible sign that the container has not been opened. On the gable box it passes through the handle. On the paper bag it hangs from the top edge like a tag. On the bottle it becomes a plain wrap-around label with the ingredient panel on the reverse. Five formats, one operation, one printing plate size.
Colour was reduced to two. The indigo is a single spot ink taken from the noren curtain at the chain’s original branch. The ochre seal is a die-cut sticker applied by staff at the counter, rotated to a diamond, and its placement is deliberately hand-controlled — no two are identical, and the studio wrote that into the operations manual rather than trying to eliminate it.
Everything is uncoated and unbleached where the food allows. The bowl is moulded bagasse. The box and bag are unlined kraft printed white. Chopsticks are untreated bamboo. The insert card is the same ochre stock as the seal and carries reheating instructions on one side and nothing on the other.
Cost fell by about a fifth against the previous mixture, largely through consolidating print runs.
The jury admired the economy of the system and the way a single component holds five very different objects together. It also noted the risk the studio accepted in leaving seal placement to staff, and judged that the resulting variation reads as care rather than as sloppiness. The entry missed the top award because the underlying containers are stock items, and the design contribution, while smart, sits on the surface of them.
Aoba Packaging Studio is a four-person office in Sendai, founded in 2019 by Kenta Murai after eight years at a Tokyo packaging manufacturer. It works with regional food producers and restaurant groups in Tōhoku, usually on budgets that rule out custom tooling, and has built a practice out of designing systems around stock formats. The studio runs a monthly clinic where local businesses can bring existing packaging for a free assessment. Murai has written a short book on belly bands. The studio's other three staff came from local print and food-service backgrounds rather than design schools, which Murai regards as an advantage when the work is mostly about operations. It has never worked with a client outside Tōhoku.
