Undokai (Sports Day) + neighborhood October sports festivals
School-based Undokai pits in-school teams (Red/White) - but the parallel October community Undokai held in chocho (neighborhood association) parks pits neighborhood teams against each other in relays, tug-of-war and dance contests, with parents, retirees and students competing for the chocho.
Local chocho (neighborhood blocks) field competing teams in the community sports festival; results are tallied per neighborhood and published in newsletters.
Each chocho recruits across generations (elementary students, parents, retirees, local shopkeepers); weeks of evening practice in the neighborhood park build cross-generational ties.
Specifically the COMMUNITY/CHOCHO undokai (distinct from the school-only version on most checklists) is a genuine block-vs-block civic competition with deep intra-block teamwork - culturally embedded and under-cited in Western lists.

Las Fallas de Valencia (Casals Fallers competition)
~750 neighborhood 'casals fallers' (faller clubs). Covering ~25% of Valencia's population. Each commission and build a satirical sculptural monument (a 'falla') up to five stories tall in their own neighborhood. All fallas compete in juried categories (Seccion Especial down to local sections), plus a separate Ninot Indultat popular-vote contest decides which figure escapes burning on 19 March.
Carnaval de Negros y Blancos (Pasto Float Competition)
Artisan collectives. Many rooted in specific Pasto barrios. Build monumental carrozas (floats) up to 15m long and 10m high over six months. Up to 50 people per collective collaborate on a single carroza. Floats compete in juried categories during the Desfile Magno; 2026 first prize ('Indomable Mujer Guerrera') scored 97.50. The Carnavalito originated in El Ejido neighborhood in 1966 as a children's version.
Lewes Bonfire Societies
Seven (sometimes counted as six) bonfire societies. Cliffe, Commercial Square, Lewes Borough, Nevill Juvenile, South Street, Waterloo, and Southover. Each represent a different quarter of the town. Every Bonfire Night they run separate processions, costumed tableaux, satirical effigies, fire sites and firework displays. Societies meet in the Bonfire Council Costume Competition at the Town Hall to compete head-to-head on costume craft.
Cruces de Mayo (Sevilla and Andalusian towns)
Neighborhood associations, hermandades, and pena clubs spend weeks building large floral cross altars in their street or plaza. Municipal juries score them on flower variety, balance, distribution, artistic lighting, traditional Andalusian aesthetic, and festive atmosphere. Specific category prizes are awarded (e.g, Penarroya-Pueblonuevo 2024 winners: Calle Sevilla, Futuro Singular, FAISEM).
Kishiwada Danjiri Matsuri
34 carved wooden danjiri floats. One per neighborhood. Are pulled at high speed by teams of hundreds through Kishiwada's narrow streets. Each neighborhood guild maintains its own danjiri, designs its happi-coat color scheme, and trains its pullers. Crews compete on speed, cornering skill (the famed 'yarimawashi'), and team coordination.
Notting Hill Carnival Sound Systems
30+ permanent sound systems (Aba Shanti-I, Disya Jeneration since 1985, Killerwatt, Channel One, Rampage, Arts-A-Light, etc.) take over specific street corners across Notting Hill, Westbourne Park, and Ladbroke Grove for the carnival weekend. Each system is a long-running crew with home turf and stylistic identity (roots reggae, ragga, dub, soca, UK garage). The parallel Panorama is the formal UK National Steel Pan Championship between steel-band crews.
