Kacoms Co., Ltd., an Osaka-based IT services company, has acquired all of the issued shares of ERAS Co., Ltd., a Tokyo startup that trains engineers for AI work and helps companies put AI into their products and operations. The parent company, Kacoms Holdings, announced the deal on PR TIMES on October 30, 2026, and said ERAS had joined the Kacoms Group.
The companies did not disclose the price or other financial terms. Neither side gave headcount figures for ERAS.
ERAS keeps its own company name and its Tokyo base in the Kanda Ogawamachi district of Chiyoda ward. Kacoms said it plans to sell ERAS's AI services alongside its own to existing customers and to combine ERAS's training platform with the group's internal education programmes.
What ERAS built
ERAS was founded on January 17, 2017, and has share capital of 10 million yen (about $65,000), according to the announcement. Its representative director is Ryosuke Chiba. The company's website says it changed direction in 2025 to focus on developing people for the AI era, under the slogan "create the era, develop people".
Its main product is Learnow, a training platform that aims to turn out engineers who can build full web applications and are also skilled with AI. Alongside training, ERAS sells several services to businesses. It designs and builds AI models, including generative AI, for new products and efficiency projects. It also develops and runs web applications and SaaS products, builds databases and data warehouses with BI analysis, designs application security, and supplies project management and IT operations support.
The company's news page shows a capital increase through a third-party share allotment completed in January 2022, without naming the investors or the amount. It also announced a partnership with TOMAP in May 2023 to train React engineers, and moved its head office in February 2024.
Why Kacoms is buying
Kacoms was founded in July 1971 and has share capital of 95 million yen (about $620,000). It is headquartered in the Shin Daibiru building in Osaka's Kita ward and is led by chairman and president Taku Shimizu. Its business covers system consulting, contract system and software development, engineering staff services, system maintenance and operation, and IT infrastructure and network operation. Kacoms Holdings is unlisted.
In the announcement, Kacoms said it wanted to pair ERAS's experience with AI tools, AI-driven development and training with its own customer base, development record, sales network and staff training setup. The goal, it said, is to build services suited to the AI era and to grow the value of the group.
Shimizu said he was pleased to bring ERAS into the group, and that combining its AI and education skills with Kacoms's long experience in building and running systems would let the group do more to support customers' digital transformation and AI adoption. Chiba said joining Kacoms opened a new chapter for ERAS, and that adding the group's customers and development capacity to ERAS's work in AI training and adoption should give clients more value.
What happens next
The companies listed five areas of cooperation. They plan joint proposals for AI implementation and business improvement work, with cross-selling to existing customers. They will share technical knowledge on AI-driven development, generative AI, data infrastructure and BI. ERAS's training platform will be combined with the group's education and training system.
The group also expects ERAS to widen its customer contacts and sales in the Greater Tokyo area, with the two sides helping each other on contract development, engineering support and project management. Staff exchanges and shared knowledge are meant to give employees of both companies more room to grow.
No targets for revenue or cost savings were published. Dealroom noted that the outcome will depend on whether the two companies can win joint proposals and roll out combined services.
Older integrators buy AI skills
Dealroom described the purchase as part of a wave of deals in which traditional Japanese IT integrators buy AI capability to keep pace as corporate AI use moves from pilots to deployment. It pointed to Suzuyo Shinwart's recent investment in Tokka Systems as a similar move.
