“The most reliable path is the one built on a solid foundation of accuracy and unwavering adherence to the rules.”
高松 達也, or Tatsuya, began his career as a diligent accountant, spending nearly a decade navigating the intricate world of Japanese corporate finance. This experience instilled in him a deep appreciation for order, precision, and the critical importance of regulatory compliance. His transition to entrepreneurship wasn't born from a desire for disruption, but rather from a frustration with the existing software solutions available to freelancers and micro-businesses in Japan. He saw inefficiencies and a lack of tailored functionality for the specific needs of sole proprietors, particularly concerning tax declarations and invoicing standards. Driven by a strong sense of self-reliance and a meticulous nature, Tatsuya decided to build his own solution. He taught himself modern web development, leveraging his existing understanding of accounting principles and Japanese business practices. For the past six years, he has single-handedly operated his invoicing SaaS, 'Kanjo Pro' (a name he chose for its directness and implied professionalism). This involves everything from front-end development and back-end infrastructure to customer support and staying abreast of ever-changing consumption tax laws. His income of ¥15M is largely reinvested, with personal spending kept to a minimum. He views his current solitary work as a deliberate, strategic phase, prioritizing the long-term stability and integrity of his service over rapid, potentially unstable growth. He values his independence and the control it affords him over the quality and direction of his product, even as he grapples with the inherent limitations of a one-person operation. His financial decisions are conservative, focusing on sustainability and building a robust safety net. He is deeply uncomfortable with the idea of taking on external investment, preferring to grow at a pace dictated by his own capacity and internal resources, ensuring the reliability his users depend on.
Background & daily life
A day in their life
Tatsuya's day begins at 6:30 AM with a light breakfast and reviewing overnight system logs. By 8:00 AM, he's at his office, dedicating the first few hours to coding and development, tackling the most complex tasks when his mind is freshest. Around noon, he takes a short break for a simple lunch, often a bento box. The afternoon is a mix of customer support – responding to emails, reviewing support tickets, and sometimes handling brief video calls – and implementing urgent compliance updates. He might spend an hour listening to a jazz podcast while processing invoices or reviewing financial reports. He typically leaves the office around 8:00 PM, eats a solitary dinner, and may do another hour of work or read industry publications before sleeping by 11:00 PM.
Lifestyle
Tatsuya lives a spartan, focused life in a compact apartment in the Shinjuku ward of Tokyo. His income affords him comfort but he prioritizes reinvesting in his business and saving. He walks or takes the train to his small, rented office space. Evenings are often spent working or catching up on industry news. Weekends might involve a visit to a local jazz club, a quiet sushi dinner at a familiar counter, or deep dives into tax code revisions. He rarely splurges on himself, viewing his current lifestyle as a necessary phase for long-term security and business growth. His social life is minimal, centered around a few former colleagues he occasionally meets for drinks.
Work life
As a solo founder, Tatsuya wears every hat. His days are a meticulously scheduled rotation of coding new features, debugging, meticulously updating the software to reflect the latest Japanese consumption tax (shōhizei) changes, responding to customer inquiries via email and occasional Zoom calls, and managing server maintenance. He uses a combination of open-source tools and a few carefully selected paid services for development and operations. The pressure to maintain flawless compliance and provide responsive support without a team is immense, leading to long hours and a constant mental juggle. He feels a profound sense of responsibility for his users' financial accuracy.
Relationships
Tatsuya is divorced and has limited contact with his ex-wife. His parents, retired and living in the countryside, call him weekly for brief check-ins. He maintains a cordial but distant relationship with a few former colleagues from his accounting days, occasionally meeting one for a quiet dinner or a jazz performance. He has no close friends and his primary social interaction outside of business is with his users, whom he views with a sense of professional obligation.
How they decide
Tatsuya is highly analytical and research-driven. He meticulously weighs options, consults relevant documentation and regulations, and often creates spreadsheets to compare potential solutions. He values proven reliability and adherence to established processes over novelty. Decisions are typically made after a period of careful consideration, prioritizing long-term stability and risk mitigation.
How they sound
Speaks in a calm, measured tone with precise diction. He uses formal Japanese (keigo) with customers and business contacts, even in informal settings. Avoids slang and emotional outbursts. His cadence is steady, almost monotonous at times, reflecting his focus on clarity and accuracy. He often pauses to carefully select the right terminology, especially when discussing technical or legal matters.
