What's with the big
(Japan) fuss?
Established Willingness to Pay
Japanese enterprises routinely pay tens to hundreds of thousands of yen per month per software subscription.
Adoption Gap = Open Market
46.2% of Japanese firms are actively evaluating AI adoption, but only 27% have implemented it. First-mover advantage is massive.
Language Barrier Is a Moat
Domestic LLM projects (NTT's "tsuzumi", NEC's "cotomi") exist precisely because overseas AI cannot operate in Japanese out-of-the-box.
Sales Talent Is the Bottleneck
~60% of foreign-affiliated companies in Japan cite sales & marketing as their hardest role to fill. We solve this for you.
AI Adoption Value Gap
Japanese enterprises report low ROI despite adoption — creating enormous demand for knowledgeable implementation partners. (PwC Japan 2025)
A Different Kind of
Market Entry Partner
We built this service because no one else was doing it right for SaaS companies.
SaaS & AI Specialization
The only Japan entry service purpose-built for SaaS and AI startups. We speak your product language and your market.
Native English + Japanese
Bilingual execution across every touchpoint — not just translation. We write your emails, your LP, your pitch decks in both languages.
Gen Z Digital Fluency
Social media algorithms, video content, inbound marketing — we grew up here. Your Japanese SNS presence is in native hands.
Execution-Focused, Not Advisory
We build your LP, post your SNS, run your sales outreach. No reports-only retainers. We deliver work product, not slides.
Fraction of the Cost
Comparable freelance engagements total ¥1–2M ($7K–$13K USD). Our all-in Starter Pack: $10,000. One invoice, one point of contact.
Not your ancient
consultancy firm.
We started as a job market service, shipped apps to the App Store, pivoted, and done all that through our 2nd and 3rd year at university.
