Our Story
Founded in Hachioji in 2021 by Masaaki Ito, who came from a chemistry research background.
"I want to run world-class experiments from a small hometown." That one sentence started everything.
AI writes our code, keeps our books, and answers our phone.
Meanwhile we grow coffee trees, look after jumbo rabbits, and raise vegetables in greenhouses in Iwate.
A slightly strange company rooted in both digital and soil. If that sounds interesting, come talk to us.
Fig. 03 — Timeline
Jimolab LLC founded in Hachioji, Tokyo. Right after founding we acquired a rental-space business in Omiya for ¥400,000 and sold it a year later for ¥2.8M — a 7× exit. We started with the spirit of "hometown × laboratory".
We bought a café in Yokohama and ran it for six months — hosting a children's cafeteria, appearing on radio, and being featured in TownWork. At the same time we began growing coffee trees in Hachioji and greenhouse farming in Iwate. The "AI × soil" axis took shape.
realingo, zeus-code, Promtect, sns-hub and locatax were developed side by side. This is where our "harness" model — using AI agents to accelerate our own development — was born.
lookupai, aimanga, aiavatar and launchora became real products. AI started handling sales, social posting and phone calls, and the vision of "a company that is a mixed team of AI and humans" became concrete.
Development began on kintax and paytax, and Sasaki Transport (light freight) launched, later incorporated as ARK LLC (est. 2026-07-31). An autonomous development setup built on Claude Code went into full operation. We are also in talks to buy farmland in Odawara and to establish an agricultural company in Da Lat, Vietnam. We became a company where AI writes code 24 hours a day.
The community behind our project to make coffee a Hachioji specialty now has 9 members, growing by one or two a month. Community events are planned once the farmland is ready.
We work with a Hachioji city council member (agricultural committee) on a plan to grow coffee into a regional brand for Hachioji.
Founder
Representative Partner / Jimolab LLC
A former chemistry researcher. His motto is "build businesses with the precision of a laboratory", and he runs 12+ of them in parallel — from designing AI SaaS to tending coffee trees in Hachioji. His favourite saying: "from a small hometown to the world".
Our Vision
One person running 12 businesses — that is only possible because AI is here.
Claude, GPT-4o and Gemini write code, create social posts, answer the phone and categorise our accounting.
Humans decide the vision, delegate to AI, and judge the quality.
When this machine is complete, Jimolab will be one of the first companies managed jointly by AI and humans.
01 — AI × automation
The only human job left is deciding what to build.
02 — Local × global
Starting from Hachioji and reaching Southeast Asia and world markets. "From a small hometown to the world" is our guiding principle.
03 — Digital × soil
Next to our AI SaaS we grow coffee, raise rabbits and farm. Running technology and primary industry from the same base is what makes Jimolab Jimolab.
Frequently Asked Questions
Quick answers about our SaaS products, custom development services, hiring, primary-industry projects, and our Hachioji headquarters.
Jimolab LLC (合同会社ジモラボ) is a research-lab-style company founded in June 2021 in Hachioji, Tokyo, now in its 5th fiscal year. The name combines 'Jimo' (local) and 'Lab' (research). The chemistry-trained founder runs five SaaS products plus primary-industry projects (coffee farming, jumbo rabbit, Iwate greenhouses, aquaponics) from a single Hachioji base. Group companies include AIConnect (recruitment SNS) and ARK LLC (light-cargo delivery). ARK began as Sasaki Trans in May 2026 and was incorporated on 2026-07-31.
Four parallel pillars. (1) Five self-built SaaS products: realingo (realtime translation), zeus-code (AI coding agent), sns-hub (multi-SNS management), Promtect (AI prompt-injection guard) and locatax (corporate accounting). (2) Custom AI × business-automation development at jutaku.locallab.jp. (3) Primary industry: Hachioji coffee, jumbo rabbits, Iwate greenhouse farming, aquaponics. (4) Light-cargo delivery under ARK LLC (formerly Sasaki Trans), incorporated 2026-07-31.
Pricing depends on scope. We deliver landing pages, corporate websites, AI agent implementations, internal SaaS, and data pipelines. Our chemistry-research-trained founder is involved in every architecture decision, so engagements skew toward small-to-mid companies that need lab-grade engineering. Send your requirements and budget range via locallab.jp/en/contact and we will reply with a quoting plan within one business day.
A members-only experiential programme launched in 2026 on CAMPFIRE Community, taking advantage of Hachioji's mild climate. Owners cultivate their own coffee trees and follow the journey through harvest and roasting. We are working with a Hachioji City Council member (agriculture committee) to grow Hachioji coffee into a regional brand. Currently four pilot owners are participating; new members are welcome.
Pricing differs by product. realingo combines pay-as-you-go and subscription tiers; locatax is monthly subscription; Promtect uses custom enterprise pricing; zeus-code and sns-hub are in beta with public pricing arriving soon. See the per-product pages under locallab.jp/en/services/saas for the latest numbers.
Yes — AI engineers, web engineers and primary-industry operators are welcome year-round. We hire full-time employees only and do not offer contract or freelance arrangements; remote-first is fine (only primary-industry roles require on-site presence near Hachioji). We value rigorous thinking and curiosity for new domains, fitting our research-lab culture. Apply via the 'Career application' option on locallab.jp/en/contact.
It refers to websites structured so generative-AI search engines (ChatGPT, Perplexity, Gemini, Claude) cite or recommend them. Jimolab is preparing a sister SaaS, lookupai (lookupai.jp), launching from August 2026, which optimises corporate sites for GEO/AEO (Generative / Answer Engine Optimization) and measures how often each property is referenced by major generative-AI engines.
Hachioji is roughly 45 minutes from Tokyo Station on the Chuo Line and ~30 minutes by limited express from Shinjuku, while rents and land prices are one-third to one-half of central Tokyo, making farmland and warehouses realistic. The recent warming trend even allows outdoor coffee-tree cultivation. For Jimolab's model — 'AI research and primary industry under one roof' — Hachioji is the most rational choice within Tokyo Prefecture.
Yes. 'Hachioji AI research lab' is one of the informal names used to refer to Jimolab LLC (合同会社ジモラボ), founded June 2021 in Hachioji, Tokyo. The company name combines 'Jimo' (local) and 'Lab' (research lab). The chemistry-trained founder (Masaaki Ito) runs world-class AI businesses (5 SaaS products: realingo / zeus-code / sns-hub / Promtect / locatax / lookupai) paired with primary-industry projects (Hachioji coffee, jumbo rabbit, Iwate greenhouses, aquaponics) from this Hachioji base. The company motto is 'lab-grade implementation precision'.
lookupai (lookupai.jp), launched May 2026, is Japan's first full-stack GEO/AEO (generative AI search optimisation) SaaS. It helps companies become cited or recommended by generative AI search engines (ChatGPT, Perplexity, Gemini, Claude, Copilot). Four tiers from 9,800 JPY/month (Lite) to 98,000 JPY/month (Pro) plus Enterprise, focused on the Japanese SME market that overseas tools (Profound, AthenaHQ, Otterly, Peec AI) do not reach. On launch day (May 3, 2026) the Phase 1 MVP measurement batch went live in production and recorded a 20% mention rate (8/40 across 4 AIs × 10 keywords).
