What is King Jim Kori Jirushi?
It is a decorative rubber stamp made with every part clear, so you can see exactly where the design will land. King Jim, the Tokyo company behind KITTA masking tape, sells it under its HITOTOKI brand for decorating planners, notebooks and gift wrap. Its news release describes it as looking like ice, which is what the name refers to.
The stamp bodies are acrylic with a rubber face. Designs include animals, plants, sweets and repeating patterns, which King Jim says suit decoration.
Why does being transparent matter?
You aim by sight: the face is visible from above, so you can line a print up with the last one. King Jim lists this as the main benefit, along with seeing how much ink the face has taken before pressing, which helps you spot a patchy print early.
Seeing the face also helps when you stack prints or chain a pattern, and when you change ink colors between impressions. King Jim says some designs are drawn to join or overlap for patterns, and it fills solid areas with fine dots so ink doesn’t bleed through to the back of the paper.
What sizes and sets are there?
Small is 22 × 22 mm, large is 33 × 33 mm and long is 22 × 66 mm, each 18 mm tall, plus six-piece boxed sets. The long size came with the second set on September 10, 2025; King Jim says it suits dividing a planner page and “partial stamping”, inking only part of a design.
| Item | King Jim’s figure |
|---|---|
| Small | About 22 × 22 × 18 mm (0.9 × 0.9 × 0.7 in) |
| Large | About 33 × 33 × 18 mm (1.3 × 1.3 × 0.7 in) |
| Long | About 22 × 66 × 18 mm (0.9 × 2.6 × 0.7 in), about 27 g |
| Six-piece box | About 72 × 72 × 20 mm (2.8 × 2.8 × 0.8 in), about 80 g |
| Pad | About 35 × 35 × 20 mm, face 25 × 25 mm, about 12 g |
The first launch had 20 small and 10 large designs plus six six-piece sets, 36 items in all. A six-piece box holds six stamps. King Jim’s launch release and the Cat set’s store page list three of 22 × 22 mm and three of 22 × 44 mm in it, not the 33 mm large size, and the three-size boxes of the second set add a 22 × 66 mm stamp (the Manga box lists four small, one 22 × 44 and one 22 × 66).
What ink pad goes with it?
King Jim’s own pad uses oil-based pigment ink for paper and dries quickly. Released on September 10, 2025, it comes in 8 original colors. The firm face keeps ink off the surrounding area and lets you use a corner to color parts of a design separately, and King Jim says the pad dries out slowly even with the lid open.
Because the stamps are not self-inking, you could also use another pad. Check the ink is made for rubber stamps and your paper; we haven’t tested any.

When did it launch and what did it win?
King Jim announced it on April 11, 2024 and put it on sale on May 24, 2024. The first-year target was 380,000 stamps. The second set and the pad followed on September 10, 2025, with a 250,000-unit target, per King Jim’s August 5, 2025 release.
That release says the first set won a Good Design Award 2024, the Bungu-ya-san Taisho 2025 idea award, and second place in the stamping-and-sorting category of the Bungu Sosenkyo 2025. Shumibun reports a third set on sale from July 29, 2026, with colored acrylic types, so the all-clear description now covers the original transparent line, not every item.
How does it compare with other stamps?
It is a pad-inked decorative stamp, so it trades convenience for placement. The Daigo isshoni. Point Stamp is self-inking and prints a word, with no pad. Midori’s Paintable Stamp Half Size is pre-inked and prints a fixed layout. Kori Jirushi suits scrapbook-style decoration where you want many colors and exact spacing.
How much does it cost?
At launch King Jim listed ¥530 (about US$3.40) for a small, ¥580 (about US$3.70) for a large and ¥2,400 (about US$15) for a six-piece set, all before tax. For the second set it listed ¥580 (about US$3.70) small, ¥680 (about US$4.30) large and long, ¥2,700 (about US$17) for a six-piece set and ¥690 (about US$4.40) for the pad.
King Jim’s online store prices are higher, and include tax: ¥704 (about US$4.50) for a small, ¥825 (about US$5.20) for a large or long, ¥836 (about US$5.30) for a pad, ¥2,904 (about US$18) for the Cat set and ¥3,267 (about US$21) for the second-set boxes. We read no explanation for the difference. Singles fall in our $$ band ($5–20) near its lower edge; boxes sit near its top.
The store showed the Cat set as unavailable on October 31, 2026. We found no US listing at Yoseka Stationery that day and could not check Amazon or JetPens.
Where is it made?
King Jim doesn’t say on the pages we read. None of its releases or store pages we opened give a country of manufacture, and King Jim is based in Tokyo. Check the package. For King Jim’s other recent designs, see the twip book clip.
Frequently asked questions
What does Kori Jirushi mean?
King Jim's release gives the reading as kori-jirushi. The name uses the Japanese word for ice, which fits the ice-like look; King Jim doesn't explain it further.
Are the stamps really fully transparent?
The handle is acrylic and the face is rubber, both clear, in the original line. In July 2026 King Jim's colored acrylic types were added, per Shumibun, so check the item before buying.
Is this a self-inking stamp?
No. Each stamp needs an ink pad. King Jim sells its own Kori Jirushi pad, and the stamps are described as suited to using several inks.
Which size should you buy first?
In our view, a small and a large from one set. King Jim says each six-piece box groups designs by theme and mixes sizes, so a set is the simplest start.
How do you clean it?
King Jim says the acrylic handle wipes clean of ink and dirt easily. It gives no cleaning advice for the rubber face in the pages we read.
What ink does the Kori Jirushi pad use?
King Jim says it is an oil-based pigment ink for paper that dries quickly, in 8 original colors. It does not list the colors by name on the pages we read.
Can you buy Kori Jirushi in the US?
We could not confirm it. We found no US listing at Yoseka Stationery on October 31, 2026, and Amazon and JetPens block our checks.
