Shop Japanese Koinobori in compact 40 cm windsocks, mid-size 50–70 cm fish streamers, larger 100 cm options and a blank 3-piece craft set. The current collection includes cloth, fabric, satin and silk designs in multiple colors, plus a Maneki Neko-themed streamer and plain Koinobori that can be decorated at home or in the classroom.
Koinobori are fish-shaped streamers best known for their association with Children's Day in Japan on May 5. Traditional and modern displays can differ in color, number and arrangement, so this collection focuses on helping you choose the actual size, material and design you want rather than assigning a fixed family meaning to every color.
Before ordering: Check the individual product page for the exact variant, size and current availability. Materials vary by listing, and the collection does not claim that every streamer is handmade, made in Japan or designed for permanent outdoor exposure.

How to Choose a Koinobori Size
40 cm Koinobori are the easiest to place in small spaces, indoor displays and compact balconies. 50–60 cm streamers add more presence while remaining manageable for most home displays. The 66–70 cm options work well when you want the fish shape to stand out clearly from a distance. Choose the 100 cm variant only when you have enough clearance for the body to extend and move without repeatedly hitting walls, branches or railings.
The blank craft set is different because it combines approximately 25 cm, 45 cm and 70 cm pieces. That stepped sizing works especially well for a classroom project or a custom three-fish arrangement.
Cloth, Fabric, Satin or Silk Koinobori
The current collection does not use one universal material. Some products are listed as cloth or fabric, several use satin, and others use silk. Choose based on the specific appearance and handling you prefer rather than assuming one material is automatically more traditional or more durable.
Satin and silk surfaces should be kept away from rough hooks and abrasive walls that could snag them. Fabric and cloth craft pieces may be easier to handle for casual decorating, but their exact weather resistance is not documented across the collection. For all of these lightweight streamers, indoor storage during severe weather is the safer default unless the individual product gives more specific outdoor-care guidance.
Japanese Koinobori Prices
Current prices across the collection run from approximately $9.99 to $22.99 depending on the product, color and size selected. The compact 40 cm options are generally at the lower end, while larger 70 cm and 100 cm variants can cost more. The live product page and selected variant are the source of truth because prices can change.
What Is Koinobori?
Koinobori are carp-shaped windsocks traditionally displayed in Japan around Children's Day, celebrated on May 5. The carp has long been used as an image of vigor and perseverance, and modern Children's Day displays commonly express hopes for children's healthy growth and future.
You may see guides that assign one exact family member to every Koinobori color. Historical arrangements have included color conventions, but contemporary sets and household displays vary. For shopping purposes, it is more useful to choose the size, colors and number of streamers that suit the display you are building.
Children's Day Koinobori Displays
A Koinobori display can be as simple as one fish streamer or can combine several sizes and colors. Outdoors, the open mouth catches moving air so the fish body fills and appears to swim. Indoors, Koinobori can also be hung from a ceiling hook, wall rail, window area or classroom display even when airflow is limited.
If you are planning a family or school craft activity, the 3-Piece Blank Koinobori Craft Windsock Set gives you plain fish-shaped surfaces rather than a finished printed design.
How to Hang and Care for Koinobori
For a windsock effect, position the mouth toward open air and leave enough clearance for the full body to extend. Do not place lightweight streamers where they will continually strike sharp metal, rough brick, branches or other abrasive surfaces.
Unless the individual product says otherwise, bring Koinobori indoors during strong wind or heavy rain. Allow damp material to dry fully before storage. Fold or roll the streamer loosely and keep it away from items that can snag silk or satin surfaces.
