What Tsuji Hongo IT Consulting Co., Ltd. does

Tsuji Hongo IT Consulting Co., Ltd. (辻・本郷ITコンサルティング株式会社) is a Tokyo-headquartered DX consulting and SaaS company that operates as the technology arm of the Tsuji Hongo Group, anchored by Tsuji Hongo Tax Corporation. Founded in May 2012 and listed on the Tokyo Stock Exchange Standard Market under stock code 476A on December 19, 2025, the company delivers one-stop back-office digital transformation services to three horizontal segments: corporate clients (accounting/bookkeeping DX consulting, HR/labor DX, low-code application development, IT security, IPO support, and post-merger integration); individual consumers (the better相続 suite of cloud services for self-service inheritance registration at ¥8,250 per service, inheritance tax filing at ¥19,800, and pre-death planning); and accounting/tax firms (the withDX DX-support platform with approximately 100 partner firms as of January 2026, plus NEXTA premium training and 実トレ examination services).

Core platforms have processed 10,000+ real estate inheritance registrations as of April 2025 and reduced payroll completion time to one-quarter of prior levels in documented client engagements.

Revenue is generated through professional consulting fees, recurring SaaS subscriptions, managed outsourcing services for accounting and HR/payroll, one-time and subscription individual consumer fees, and accounting-firm subscription education services. Distribution combines direct corporate sales, self-service web platforms for individuals, partner referrals through bank and securities-firm alliances, and a strategic capital and business partnership with Itochu Corporation for mid-tier SME DX projects. The company was formed in part through the October 2022 business integration with better Inc. and expanded via the October 2024 acquisition of Colony Interactive Inc., and has launched the TH-AI generative AI initiative in May 2026 in collaboration with the parent tax corporation.
