Kozaru review
A focused, family-friendly dojo system with a capable free plan.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Kozaru is cloud software for martial arts schools, dojo operators, and associations that need administration built around training progression and family participation. It brings together student and family records, attendance, belt and rank tracking, gradings, syllabus management, forms, waivers, timetables, class booking, and membership-fee collection. Families get a phone-friendly app for schedules, attendance responses, balances, and belt progress, while schools can provide kiosk check-in and maintain compliance records.
The free plan is unusually broad for a small dojo. It includes registration and attendance, gradings and syllabus, timetable and kiosk tools, forms and waivers, and member payments through the school's Stripe account. A 30-day trial is available without a card, although text messages require a card during the trial and on the Free plan. The Subscription plan supports up to 20 active students, with additional active students billed separately from the 21st and no ceiling or higher pricing tier listed in the plan structure. An AI helper adds daily reading of dojo numbers and a natural-language action box.
Kozaru's strongest fit is a family-oriented school that wants martial-arts-specific records rather than general gym software. Shared family purses, multiple children, belt progression, grading readiness, class booking, waiting-list notifications, and spreadsheet and calendar-feed exports cover the operational details that matter to smaller schools. The main trade-offs are platform and payment fit: it is offered on the web, and membership billing runs through the school's own Stripe account. Schools needing broader platform coverage, a different payment setup, or always-on support should consider an alternative. Small dojos that value family management and can work within Stripe should find the feature mix practical.
