There's a phrase every service worker in Japan knows: okyakusama wa kamisama. The customer is a god. Not a king. Kings negotiate. Gods are served.
The bar, concretely
In most markets, CX quality is a spectrum. Fast beats slow, warm beats cold, but there's a wide band of "fine." In Japan the band is thin. Here's what sits inside it.
Language has registers, and the wrong one is an insult. Keigo, honorific Japanese, isn't politeness sprinkled on top. It's a grammar system: respectful forms for the customer's actions (sonkeigo), humble forms for your own (kenjōgo), and a polite baseline (teineigo), running in parallel through every sentence. Mix the layers once and the customer doesn't hear a small mistake. They hear "this company doesn't take me seriously."
"No" is never said, but it must be communicated. A rep who tells a customer "we can't do that" has failed twice: once at the task, once at the relationship. The craft is delivering a refusal so the customer arrives at it themselves, cushioned, relationship intact. That's not scripting. That's judgment, live, on every call.
Silence is data. An unhappy Japanese customer usually won't complain. They go quiet, then leave. Politely, permanently. One number that shaped how I think: in a Japanese consumer survey, over 80% of people said they call support only after failing to find the answer online themselves. By the time the phone rings, the customer has already tried and failed once. The call starts below zero.
Apology is structural. The apology comes first, before fault is established, because it acknowledges the customer's inconvenience, not the company's guilt. Explain first and apologize later and you've made it worse.
None of this shows up in a CSAT dashboard. All of it decides whether you keep the customer.
Why this breaks most AI
Most AI customer-service products are built to a bar of "resolves the ticket, sounds reasonably human, most of the time." In the US or Europe, that clears the band of fine. In Japan, every weakness gets amplified.
A model that's 95% right on keigo is 100% wrong to the customer who hits the 5%. A bot that says "I cannot do that" is doing the exact thing the best human rep is trained never to do. A system that can't read hesitation and softened language will miss the unhappy customer entirely. That customer will never type "I'm frustrated."
And the stakes aren't small. Japan's call-center services market did roughly ¥1.3 trillion in sales in FY2023. The phone is still the front door of the business here, preferred for everything from billing questions to complaints. Meanwhile the labor to answer those phones is disappearing: Japan is projected to be short about 3.4 million workers by 2030, and on some projections around 11 million by 2040, with service work among the hardest-hit categories.
So: the market that most needs this technology is also the market with the least tolerance for getting it wrong. That's the whole puzzle.
Why it's the best teacher
"Human-like" is an empty word until a market forces you to define it. Japan forces the definition. Human-quality means: right register, sustained across the whole conversation. Refusals that preserve the relationship. Hearing what isn't said. Apologizing in the right order. Knowing when to hand the conversation to an actual human, and doing it gracefully.
Each of those is a specific engineering and design problem. You don't get to hide behind "the model is pretty good." The floor is high, so the craft has to be.
The discipline transfers, too. A product that clears the Japanese bar will find the American bar, the European bar, the Southeast Asian bar downhill from there. Hard markets don't just test products. They shape them.
Why I'm here
People ask why a foreign founder would pick the market with the highest service standards, in the category where those standards bite hardest. The short version: this is where great service was refined into a craft over generations. If you want to build human-quality CX, you go where "human quality" means the most, and you do the work under that bar.
That's what this newsletter is: notes from the attempt. What the floor taught me, what building under the bar is teaching me now, what I wish someone had told me before I started. Setbacks included. Especially those.
If you're a founder eyeing Japan, or someone who cares about the craft of service, I'll try to be useful to you here, every two weeks.
