About JPSG

JPSG Inc. is a Japan-based business development company that helps overseas companies enter and grow in the Japanese market — not through research and advice alone, but by carrying out the market entry itself.

We run two service lines. For companies that want to sell into Japan, we handle outbound sales, meetings, quoting, and account management on the ground. For companies that want to source from Japan, we identify and approach suppliers, manage RFQs through to a qualified quote, and stay on as your contact with the supplier afterwards. Either way, the work is done by us, in Japan, on your behalf — not delegated back to you as a report.

Entering Japan on your own means navigating a language barrier, an unfamiliar decision-making culture, and — if you want a real local presence — the cost and time of incorporating a Japanese entity before you've even tested the market. JPSG lets you start operating in Japan from week one, without setting up an entity or hiring.

About the Representative

Tatsuro Yamamoto — CEO

After graduating in 2017, I started my career in Southeast Asia — a year in Indonesia, then seven years in Singapore, working in sales and business development at both Japanese and non-Japanese manufacturing companies.

Based out of Singapore, I covered accounts across Japan, ASEAN, and Europe, mostly in B2B manufacturing — new business development, account management, and the full range of what outbound sales actually looks like day to day.

Working at a non-Japanese local company meant constantly coordinating across nationalities, business customs, and manufacturing sites that shared no common playbook. Through that experience, I felt firsthand how difficult it is for a company to enter a market it doesn't already understand.

What stood out to me most was entering the Japanese market specifically. I met many non-Japanese companies that wanted to expand into Japan, but the language barrier, the difficulty of hiring local sales talent, Japan's own way of doing business, and the cost of setting up a local entity kept most of them from ever making a serious attempt.

To close that gap, I founded JPSG in 2026 and launched a Japan market development service for overseas companies — built for situations where setting up a Japanese entity, hiring locally in Japan, or hiring Japanese-speaking staff back home is difficult, and where it isn't yet clear whether the Japanese market is worth the investment. It lets a company start real sales activity in Japan even at that stage.

We'll keep expanding and improving what we offer, flexibly, so your business can keep growing in the Japanese market.

If you have any concerns around doing business in or with Japan, please don't hesitate to reach out.
