About us

About us

Discover, validate, and cultivate. Managing the Japanese business to the very end.

We discover innovative products from overseas, validate them in the Japanese market, and build sustained sales. From market entry planning to sales, logistics, and after-sales support, we manage the entire process and take responsibility as a Japanese company serving our business partners. Takumi Innovators handles product discovery and commercial negotiations overseas, while RAYZON manages e-commerce and retail sales in Japan. NEXTSEED brings these capabilities together and runs the business.

Where market entry stalls

In Japan, a great product alone is not enough

  1. Translation alone does not constitute localization.

    Expectations regarding usage scenarios and quality differ in Japan.

    We verify selling points and price ranges while simultaneously preparing Japanese documentation, certifications, and after-sales support systems.

  2. Low quotes alone do not build trust.

    Japanese business partners make decisions only after verifying quality, supply stability, and accountability.

    We build trust through prototyping, supply terms, and test sales.

  3. Initial price reductions can limit future sales channels.

    Early discounts and cost structures can eliminate the potential for retail expansion.

    We design e-commerce and retail pricing and product lineups as a single unit, calculating overall profitability from the market entry stage.

Capabilities

Discovery, validation, and operation. Three essential strengths for Japanese market entry, provided by a single team.

01

Discover

The ability to identify products that will sell in Japan

Through Takumi Innovators' network of startups and manufacturers in Shanghai and Shenzhen, together with exhibitions and field research, we continually discover products with potential in Japan. We assess not only technical innovation but also fit with Japanese standards, price ranges, and usage scenarios.

02

Validate

The ability to test on a small scale to confirm demand

Before making a large investment, we use Makuake and small-scale test sales to learn who buys and why. Based on the response, we decide early whether to improve the product or hold off, focusing inventory and promotion on products that show promise.

03

Grow

The capability to maintain continuous sales operations

RAYZON's operations team handles marketplace management on Amazon and Rakuten, sales to electronics retailers and specialty stores, import logistics, Japanese-language customer support, and support for repairs and replacements.

Test Sales

Test small first with new categories where demand is uncertain
