Hiroshi Nakamura worked at a repair counter in Akihabara — Tokyo's famous electronics district — for 4 years, earning ¥280,000 per month. The shop earned ¥3 million+ monthly from his work.
"Akihabara is where enthusiasts go," he says. "But Shinjuku is where professional Tokyo lives. I wanted to serve a different customer — one who needed their device fixed quickly and professionally, and was prepared to pay well for it."
In 2024, Hiroshi opened a shop in Shinjuku's west exit business district — surrounded by Tokyo's corporate towers, major hotels, and international businesses.
He set up RepairCoreX before opening.
"Japanese customers expect perfection in documentation," he says. "Every repair needs a proper 領収書. Every warranty needs to be in writing. Every device needs to be photographed before and after. RepairCoreX does all of this automatically. I could not have met the Japanese professional standard without it."
The Expat Discovery
Within his first two weeks, Hiroshi discovered an unexpected market: Shinjuku's large expat community — English-speaking, Korean, Chinese — who struggled to communicate at Japanese-only repair shops.
RepairCoreX's digital job tickets and invoices could be presented in English. Hiroshi's basic English was enough. Within 90 days, he was the most-reviewed repair shop in Shinjuku on Google Maps in both Japanese and English.
"My Google reviews in English from expats drove Japanese customers to me," he says. "They saw a high-rated shop and felt confident. The English reviews were social proof that transcended language."
Month by Month
Hiroshi earns ¥1,800,000–¥2,000,000 monthly net. He is planning a second location near Shibuya.
"Tokyo has 14 million people," he says. "And almost no professional independent repair shops. The market is completely open to anyone willing to meet Japanese documentation standards."
