What Is Kaishi? The Folded Paper Tea Guests Carry for Sweets
Oct 01, 2026
Quick answer: kaishi (懐紙) is folded paper carried by guests in chanoyu. It is most commonly used as a small personal plate for wagashi, but it can also be used for wiping fingers or the lip area after drinking tea, depending on the procedure and school. The word is older than tea ceremony itself: kaishi originally means paper carried inside one's clothing and was also used for writing poetry and notes.
What is kaishi?
Kaishi is one of the standard personal items a guest brings to a tea gathering.
Urasenke's introductory utensil guide describes it primarily as paper used when eating sweets and notes that guests carry it with them. Omotesenke likewise defines kaishi as paper kept on the person during a tea gathering and used for sweets, tea and parts of the kaiseki meal.
Unlike a bowl, whisk or kettle, kaishi belongs to the guest's personal kit rather than the host's permanent set of tea utensils.
What does “kaishi” mean?
The characters 懐紙 literally refer to paper carried at the breast or inside one's clothing.
Historically, folded sheets could be kept inside the kimono and used whenever paper was needed. Long before modern tissues or notebooks, this made kaishi a portable writing and practical paper.
That older meaning helps explain why the same word appears in both tea culture and the history of Japanese calligraphy.
What is kaishi used for in tea ceremony?
The most familiar use is for sweets.
When wagashi is served, the guest takes a sheet or folded portion of kaishi and uses it as a clean personal surface for the sweet. A sweet pick or kuromoji may then be used depending on the type of confection and serving method.
See why Japanese sweets are served with matcha.
Is kaishi a plate?
Functionally, it can become one.
JAANUS describes guests placing sweets onto the stiff paper they have brought with them. The beauty of kaishi is that a flat stack carried on the person can become a small disposable plate exactly when needed.
It is therefore better understood as multipurpose personal paper than as a dedicated ceramic substitute.
Is kaishi used when drinking tea?
Yes, in some procedures.
Urasenke's guide to drinking usucha instructs the guest to clean the part of the tea bowl touched by the mouth with the fingers, then clean the fingertips with kaishi.
Omotesenke's glossary also records kaishi being used to wipe the drinking area of the bowl in koicha practice.
The exact action varies with school and type of tea, so a single etiquette sequence should not be presented as universal.
Is kaishi the same as a napkin?
Not exactly.
A napkin has one primary dining function. Kaishi historically combines several roles: sweet plate, wiping paper, writing paper and portable sheet for small practical needs.
That flexibility is why translating it simply as “napkin” loses much of the meaning.
Is kaishi always white?
No.
Plain white kaishi is common and highly versatile, but tea shops also sell seasonal papers with coloured edges, watermarks, printed motifs or subtle decoration.
Urasenke beginner reports even mention students bringing seasonally illustrated kaishi to practice. Decoration can therefore add seasonal character without changing the basic function.
Are there different sizes for men and women?
Yes, traditional tea practice recognizes different sizes.
Urasenke states that men's kaishi is larger and women's smaller because the paper is carried inside clothing. Omotesenke's glossary similarly distinguishes a larger size used by men and a smaller size that can be used by both men and women.
Exact commercial dimensions vary, so it is better to follow the requirements of the tea school you practise.
Do guests bring their own kaishi?
Yes.
Urasenke lists kaishi among the standard personal items students should bring to beginner practice, alongside fukusa, fan, sweet pick, kobukusa and fukusa case.
This is important: kaishi is not normally something the host hands to each guest as disposable tableware. It belongs to the guest's prepared kit.
How is kaishi carried?
Traditionally it is folded and kept inside the kimono.
Today practitioners wearing Western clothing often carry it inside a fukusa-basami or similar tea wallet together with other small guest utensils.
The principle remains the same: the paper is kept clean, flat and ready to use without becoming a loose object in the tea room.
What is the difference between kaishi and fukusa?
- Kaishi — paper carried by the guest; commonly used for sweets and small wiping tasks.
- Fukusa — silk cloth used during temae for purification and handling of utensils.
One is paper and usually guest-facing; the other is textile and closely tied to the host's preparation.
What is the difference between kaishi and chakin?
- Kaishi — dry paper used by the guest.
- Chakin — reusable white cloth used damp by the host to wipe the tea bowl.
They can both participate in keeping the bowl and hands orderly, but they are not substitutes.
Why is kaishi connected to poetry?
Because kaishi existed as carried paper before it became one of the familiar personal items of chanoyu.
Omotesenke's glossary records a second historical meaning: paper used for writing waka, linked verse and poetry. Kyoto National Museum preserves thirteenth-century examples known as the Kasuga Kaishi, sheets carrying waka composed at poetry gatherings.
That history explains why museum searches for “kaishi” can produce calligraphy rather than tea accessories.
Can old kaishi become a hanging scroll?
Yes.
A historically important poem, letter or calligraphic sheet originally written on kaishi can later be mounted and preserved as a scroll. Urasenke even lists waka or hokku written on kaishi among the kinds of calligraphy that may appear as a hanging object in the tokonoma.
This creates an interesting loop: paper once carried on the body can later become the central visual object in a tea room.
See what the hanging scroll means in a Japanese tea room.
What kind of paper is kaishi?
Modern tea kaishi is usually a clean, absorbent Japanese-style paper made to fold neatly and handle sweets without falling apart immediately.
Historically, several high-quality Japanese papers were used as carried paper. Omotesenke mentions papers such as danshi, sugiharagami and hōshogami in the broader writing-paper sense of kaishi.
JAANUS describes danshi as an important Japanese paper that was folded and carried as kaishi and also used for cakes and tea-related wiping.
Is kaishi disposable?
Modern tea kaishi is normally treated as personal paper and used sheets are not returned to the host.
That is one reason it is carried as a stack rather than as a precious individual object. The value lies in having a clean, prepared sheet at hand.
Do you need kaishi for matcha at home?
Not if you are simply making matcha for yourself.
It becomes useful when you serve Japanese sweets in a tea-like setting, attend a tea gathering or want to practise guest etiquette. For casual use, it is also an elegant way to serve a small wagashi without adding another dish.
Kaishi in one sentence
Kaishi is the folded personal paper carried by a tea guest, used especially as a plate for wagashi and for small wiping tasks, while preserving an older Japanese tradition of portable paper for poetry, notes and everyday use.
