One link, students on four continents: how Shion built a Japanese language academy on Pensight

Most people think you need English to build a business with people overseas. Shion proved you can do it in Japanese.

She runs Kotomusubi, which is really two businesses sharing one mission. One teaches Japanese to learners around the world. The other trains Japanese people who want to become Japanese teachers themselves. Her students sit in the US, Canada, Argentina, the UK, Estonia, Hawaii, and Austria. She runs the teaching side on Pensight, and she runs it alongside Sumika, who handles the systems so Shion can focus on teaching. When we got on a call, what came through was not a tool review. It was someone who spent seven years looking for work she could do from anywhere, and finally built it.

The seven-year search for location-independent work

Shion's first career was at a credit union in rural Hokkaido, on the standard rails: get a steady job, build a career, settle down. Then a senior colleague six years ahead of her announced she was leaving for a working holiday in Iceland. "I thought, wait, you're walking away from that career to do this?" Shion said. It shook her, and then it freed her. If someone could choose that as an adult, so could she. A year later she quit, and at around twenty-one she went to study in Australia by herself.

That trip taught her two things: the world was bigger than she had assumed, and language was the key that opened it. She booked a Cebu language program in the Philippines to push her English further, paid for it, and then COVID hit. The school went bankrupt and disappeared. With her job already gone and her plan erased, she asked a sharper question: what kind of work would never strand her like that again?

The honest answer is that she tried almost everything first. Web design school, social media management, video editing courses. She invested in herself constantly, and most of it did not monetize, or monetized at a rate that kept falling as the market filled up. She did live streaming for two years after a friend invited her in, and it worked, but it was pure labor. "If I didn't show up, there was no income," she said. She pushed so hard she hurt her throat, one step from surgery, and had to stop. Then a marketing role took her back to Cebu for about a year and a half. Useful, but on its own, not the thing.

The thing arrived when she combined two ideas. She learned that teaching Japanese online required no certification, and she already had the one skill she could never lose: she is a native speaker. She started as a side gig, registered as a teacher on Preply, and offered her first lessons at around five dollars for fifty minutes. "Day one, I made money. Even at five dollars, I monetized," she said. The price was tiny, but the proof was huge. She did not need English to work with people abroad. Her own language was enough.

Replacing the patchwork

Before Pensight, the teaching ran on three tools that did not talk to each other. Lessons happened on Google Meet, student chat lived in Slack, and bookings went through formrun, a Japanese scheduling tool. She had tried an overseas option too, but it was missing pieces and she still had to stitch things together.

The piece that hurt most was money. Japanese tools mostly let her price in yen only. For a roster of students paying in dollars, that meant adding manual currency notes and eating the exchange-rate gap every time. "I kept searching for a better platform, but there was almost no information, and no one around me had used the overseas ones," she said.

Takashi, through Moshi, pointed her to Pensight, and the math finally collapsed into one tool. Lessons, student chat, and booking all live in one place. Pricing supports both yen and dollars cleanly, which for an international roster is not a nice-to-have, it is the whole point. "It's built for an international audience, so the yen and dollar display is easy to read and easy to use," she said. "One platform does it all."

The record button that changed her week

The feature she keeps coming back to is recording. On Pensight, she presses one button, the call records, and when she says goodbye it lands in the student's chat automatically. No hunting for a file, no copying a URL, no pasting it into a separate thread.

That sounds small until you look at how a teaching day actually runs. "A Japanese lesson is basically fifty minutes, and you've got the last ten to send messages and prep for the next student," she said. With Google Meet she was digging up the recording, copying the link, and pasting it in during exactly those ten minutes. With Pensight it is already sent. "I press record, say bye, and it's done. It's a real time-saver."

It does more than save minutes. The recording becomes part of the product. When Shion migrates teachers off other platforms, often with a price increase attached, the record feature is what makes the higher price feel like a gift to the student rather than a cost. "When you raise prices, you want there to be a clear plus for the student," she said. "Being able to say, here's your recording to review, plus group lessons are coming, makes the move easy to ask for." Her students have responded well to it, and she now treats it as a standard reason to recommend the platform.

Going from solo to a team

For a long time Kotomusubi was just Shion, and the course she dreamed of running felt years away. Then she met Sumika in Cebu, where they worked in the same department, Shion as a staff member and Sumika as an intern who joined her team one month before Shion decided to leave. They overlapped by a sliver. "Honestly, scaling wasn't even the plan," Shion said. "I figured I might get there one day, alone, in who knows how many years. Meeting Sumika is what made me think, we could actually build the course."

The split is clean. Shion creates the curriculum and decides what she wants to teach. Sumika figures out how to deliver it, choosing and wiring up the tools, building landing pages, and managing the day-to-day. "Shion hands me the material or the curriculum she wants out there, and I work out how to ship it with the right tools," Sumika said. "We use Pensight, we use Notion, whatever fits. But honestly, Pensight being all-in-one made my side of the work a lot simpler."

That admin layer is also how the course students get supported. Sumika holds the logins for the Kotomusubi headquarters account, Shion's personal account, and all of the roughly ten course students' accounts, almost like an admin role. From there she runs onboarding, builds landing pages, and walks each new teacher through the parts that scare people about a new tool. Kotomusubi runs internal study sessions for exactly this: live screen-shares showing how to connect a calendar, create a product, set up memberships and video Q&A, then archived so members can rewatch. "New tools always come with hesitation," Sumika said. "So we just sit down and set up the calendar link, the product, the Stripe connection, all of it together."

What other creators can take from Shion

First, your native skill might already be the business. Shion did not invent a new product. She noticed that the one thing she could never lose, her own language, was something people across the world would pay for, and she built around it.

Second, the patchwork is the tax. Three tools that do not talk to each other cost you the ten minutes between every lesson and the exchange rate on every payment. Putting lessons, chat, booking, and recording in one place is what turned Shion's teaching from a juggling act into a routine.

Third, a price increase needs a visible plus. Shion does not raise prices and hope. She pairs the increase with something the student can see and feel, a recording to review, group lessons coming, so the higher number reads as more value, not less.

Shion is moving from one-on-one lessons toward group lessons and, later, coaching, raising what a single teacher can earn while opening the door for the teachers she trains to do the same. If her story made you want to turn your own skill into something you can run from anywhere, you can start building on Pensight today, free. We will be sharing more creators like Shion who are building their next chapter on Pensight in the coming weeks. Stay tuned.
