Core offering

KEC Miriz is a Japanese EdTech venture that develops and sells proprietary educational content to learning centers and schools. Its two core products are Prokura (a Minecraft/MakeCode-based programming education franchise package) and CHATTY (a Zoom-based online English conversation service for educational institutions), delivered with curriculum, teacher training, and dedicated supervisor support.

Product overview

KEC Miriz operates as an EdTech venture offering two core educational content products: Prokura (プロクラ / Programming Cloud) — a Minecraft/MakeCode-based visual programming franchise package targeting children aged roughly 6–15, delivered to learning centers and school corporations via a FC model with curriculum, teaching materials, instructor training, and dedicated supervisor support; and CHATTY — an educational-institution-only online English conversation platform using Zoom video sessions with original textbook-aligned curriculum, 1-on-1 or group formats, and native-speaker instruction. Prokura has multiple variants: the core FC package for private operators, a school法人 version for classroom use, and a high-school Information I (情報Ⅰ) curriculum module with an LMS. All products are developed in-house and supported by a dedicated SV (supervisor) system.

Expansion highlights6 records

Direct peers

• Aviva: Aviva operates children's programming schools in Japan with a franchise-like model targeting existing learning center operators looking to add programming offerings. Directly comparable to Procla in customer base, delivery format, and curriculum positioning.
• TechAcademy: TechAcademy is a leading Japanese online programming education platform serving both individual learners and corporate training buyers. While delivery is online rather than franchise classroom, it competes for the same K-12 and adult learner EdTech wallet as Procla and represents a comparable pricing tier.
• CA Tech Kids: CA Tech Kids operates one of Japan's largest children's programming education franchise networks (Tech Kids School), directly competing with Procla for learning center partners and student enrollment. Both target the same K-12 segment with multi-location classroom delivery models.
• NativeCamp: NativeCamp is Japan's largest subscription-based online English conversation service, offering unlimited 1-on-1 lessons with native instructors. It is the most direct competitor to CHATTY in the Japanese online English conversation market for both consumer and school customers.
• CodeCamp: CodeCamp provides online 1-on-1 programming lessons in Japan with a similar instructor-led subscription model to how CHATTY delivers English conversation. Comparable in subscription-based educational delivery for Japanese learners and in serving both individual and institutional customers.
• DMM Eikaiwa: DMM Eikaiwa (DMM English conversation) is a major Japanese online English conversation service operated by DMM.com. It competes with CHATTY for the same Japanese learner audience and school institutional buyers, with similar unlimited-lesson subscription models.
• Star Programming: Star Programming runs a network of children's programming schools in Japan using a franchise-like model targeting learning centers and after-school programs. Directly comparable to Procla in target customer (learning center operators), delivery format (in-person small-group classes), and curriculum positioning.

Broad incumbents

• ECC: ECC is one of Japan's largest established English education companies, operating language schools, corporate training programs, and online services. While much broader in portfolio, ECC competes with CHATTY for school and corporate English training contracts and represents a deep-pocketed incumbent.
• Berlitz Japan: Berlitz Japan is a long-established English and language education provider with physical classrooms and corporate training offerings. It competes with CHATTY in the school and corporate language training market as a global incumbent with deeper resources and brand recognition.

Others

• Microsoft Japan: Microsoft Japan is the provider of Minecraft Education Edition and MakeCode, the core technology platform on which Procla's entire programming curriculum runs. While not a direct competitor, Microsoft is the critical enabling platform partner whose pricing, roadmap, and licensing decisions directly shape KEC Miriz's economics.
