What ReYuu Japan does

ReYuu Japan Inc. (formerly Nihon Telephone Co., Ltd.; TSE Standard ticker 9425) is a Japan-based reuse-mobile device operator founded in June 1988 and headquartered in Osaka with a secondary headquarters in Tokyo. The company procures used smartphones, tablets, and PCs—primarily from corporate clients and international markets (Hong Kong via its HKNT CO.,LTD subsidiary, and Dubai)—and processes them through its ISO/IEC 27001-certified Mobile Refurbish Center in Osaka, which performs data erasure, cleaning, inspection, and quality grading using proprietary software co-developed with Planetex alongside industry-standard Blancco and FutureDial tools.

The company monetizes through four primary streams: (1) B2C and B2B resale of refurbished devices via its own ReYuu Store e-commerce platform and third-party marketplaces (Rakuten Ichiba, Amazon Japan, Mercari Shops); (2) corporate mobile-device and tablet rental, including bundled SIM/voice/data subscription plans (Voice Fixed-Rate Biz Plans, Data-Only Plans, and the optional Smart Rental Compensation add-on at 550 yen/month); (3) an integrated subscription service bundling devices with partner SaaS (e.g., Omotenashi Suite, ProTeck ID Checker) for enterprise DX/security use cases; and (4) corporate buyback/purchase of used mobile and IT equipment with certified data erasure. Distribution combines dedicated enterprise sales teams, franchise/partner networks, and major carrier partnerships (SoftBank, IIJ, QTnet, Kanematsu Communications). FY2025 (year ending October 2025) revenue was 6,259 million JPY, of which 98% derived from reuse-mobile activities.

Following its 2024 rebrand and the December 2024 transition to AI Fusion Capital Group as its indirect parent company, ReYuu Japan has pivoted toward a circular-economy positioning and, in 2026, established ReDigital Corporation as a wholly-owned subsidiary targeting cryptocurrency treasury and a potential Dogecoin ETF in Japan via a partnership with House of Doge and ABC Corporation. The company holds the first-ever Reuse Mobile Japan (RMJ) operator certification (No. 201101) and was ISO/IEC 27001:2022-certified in December 2024, and it distributes internationally through HKNT in Hong Kong and partner networks targeting the Middle East. As of April 2026 the company employed approximately 50 people across its Osaka HQ, Tokyo HQ, and the Mobile Refurbish Center facility.

Direct peers

• IOSYS (イオシス): Japanese listed (TSE: 2719) retailer specializing in refurbished and used smartphones, tablets, and PCs. Most directly comparable peer in Japan — overlapping product mix (refurbished iPhones, iPads, Android), similar B2B and B2C channels, and comparable geographic focus on the domestic reuse-mobile market.
• Belong Inc. (ビロング): Japan-based certified refurbished smartphone specialist (including Rakuten Mobile partnership). Directly competes with ReYuu in the certified pre-owned smartphone category with similar grading, warranty, and data-erasure standards.
• EcoRing (エコリング): Japanese reuse and refurbished goods specialist with mobile devices as a key category. Operates a buyback-to-redistribution model similar to ReYuu, with comparable emphasis on quality inspection and corporate/consumer channels.
• Musubi (ムスビー / 株式会社モバイル): Japanese certified used smartphone retailer focused on refurbished iPhones and Android devices. Directly comparable on product mix, grading standards, and online distribution model targeting cost-conscious consumers.
• Back Market: Global certified refurbished electronics marketplace (smartphones, tablets, laptops). Comparable in certified-refurbished retail model with quality grading, warranty, and marketplace-style distribution — although operates primarily in Western markets, similar business mechanics.
• Janpara (じゃんぱら): Long-standing Japanese used electronics retailer specializing in smartphones, tablets, PCs, and audio equipment. Operates both brick-and-mortar stores and online channels directly comparable to ReYuu's B2C reuse-mobile retail model.
• Daiwan Telecom (ダイワンテレコム): Japanese retailer of refurbished and used mobile devices including iPhones, iPads, and Android. Direct overlap in product mix and customer segment; competes for similar cost-conscious consumer and small-business buyers.

Broad incumbents

• Geo (ゲオ) / Geo Mobile: Major Japanese second-hand retailer (CDs, DVDs, games, books) that also operates a used smartphone trade-in and sales business. Overlaps in used-device retail but operates a much broader portfolio, with reuse mobile as one of many categories.
• Rakuten Mobile: Major Japanese mobile carrier and operator of the Rakuten Ichiba marketplace where ReYuu sells. Adjacent rather than directly competitive — ReYuu both partners with and competes against carrier trade-in and device-recycling programs.
• Mercari (メルカリ): Major Japanese C2C marketplace (including Mercari Shops for merchants) where ReYuu lists reuse mobile devices. Acts as both a distribution channel and a competitive alternative for buyers of used smartphones.
