Kamifūsen
In its own language: 紙風船
Japanese paper balloons enjoyed as self-inflating toys, gifts and festival lanterns
Kamifūsen are traditional Japanese balloons crafted from thin washi paper. Loved across Japan as bouncy children's toys that draw in air when batted, they also appear as colourful medicine adverts and as glowing hot-air lanterns released during winter celebrations in Akita.
When is Kamifūsen kept?
Kamifūsen is kept on year-round, with festival flights on 10 February.
Kamifūsen are traditional Japanese paper balloons made from crisp, lightweight washi. First popularized as affordable toys in neighbourhood sweet shops, they are famous for their ability to stay inflated through gentle batting. Beyond children's pastimes, these paper spheres and cubes have served as promotional gifts from travelling medicine peddlers and as giant illuminated lanterns sent aloft during regional winter festivals to bring good fortune.
Paper balloon play
Small kamifūsen are crafted from glossy, air-resistant washi paper that holds creases and recovers its shape easily. Each ball has a small open vent. When struck upward repeatedly with the palm, the balloon does not collapse. Instead, the force of each tap draws outside air into the opening, keeping the sphere plump or reinflating a crumpled one. Historically, children bought these lightweight novelties from local sweetshops, called dagashiya, as a cheaper substitute for imported rubber balls. Modern players still enjoy batting them indoors, and makers also fold the paper into decorative creatures and fruits.
Medicine boxes and square balloons
Not all paper balloons are round. A box-shaped version, called kakufūsen, became closely linked with travelling medicine merchants from Toyama. These salesmen visited households under a traditional commerce practice known as okigusuri, in which a chest of remedies and dressings was left with a family free of charge. When the vendor returned to restock used items and collect payment, he often gifted brightly printed square paper balloons to the household children. These promotional toys entertained young family members while advertising the medicine company brand.
Winter festival in Akita
In the northern city of Semboku, Akita, paper balloons take on monumental proportions at the Kamihinokinai Paper Balloon Festival. Held annually on 10 February, the event fills the night sky with hundreds of vast hot-air balloons made of paper and lit from within. Local tradition credits Edo-period scholar Hiraga Gennai with introducing paper balloons to the area during the eighteenth century as entertainment and signalling markers for local copper mines. Residents now release these glowing lanterns into the winter air to pray for good fortune and health in the coming year.
How Kamifūsen is kept
In daily life, people play with small kamifūsen by batting the paper sphere gently into the air using their open palms. The rhythmic tapping pulls fresh air through the small hole, maintaining its shape during play. During the annual winter gathering in Semboku, community members construct enormous hot-air paper balloons, illuminate them, and release hundreds into the night sky on 10 February to wish for good fortune. In the past, families also received square versions from visiting medicine sellers as gifts for their children.
When and where
Kamifūsen toys are enjoyed at any time of year. The large-scale hot-air balloon tradition takes place annually on 10 February during the Kamihinokinai Paper Balloon Festival in Semboku.
Paper balloons are found across Japan, formerly in sweetshops and currently in souvenir stores and online. Specific traditions belong to Toyama, home of the medicine merchants, and Semboku in Akita Prefecture, where the festival is held.
What Kamifūsen means
Floating paper balloons carry wishes for good fortune in the coming year, particularly when launched as glowing lanterns during winter celebrations in Akita. Historically, smaller paper balloons represented accessible entertainment for schoolchildren, hospitality between medicine merchants and their clients, and ingenious Japanese paper design.
