Winning Field Kamakura Office

Win Japan.

Your Strategic Partner for Digital Advertising in the Japanese Market

Most foreign companies lose money on Japan advertising — not because Japan is impossible, but because they lacked a Japanese market strategy from the start.

WinningField bridges the gap: bilingual strategy consulting + full-service ad operations, from a trusted partner based in Kamakura, Japan.

Does This Sound Familiar?

🗾

"Japan is a black box"

You don't know which platform, targeting, or message will work for Japanese consumers

💸

"Money wasted on ads that didn't convert"

You ran campaigns but saw zero ROI — because the strategy wasn't Japan-specific

🗣️

"No bilingual strategy partner"

Your agency speaks Japanese but can't explain strategy in English — and vice versa

📊

"Reports, but no insights"

You receive performance reports but have no idea what to do next

🏢

"Can't find a partner who understands both"

Most Japan agencies focus on tourism/inbound, not on your B2B or SaaS model

🔄

"High setup costs, slow start"

Japan market entry takes too long and costs too much without the right partner

WinningField was built for exactly this challenge. We're not just ad operators — we're strategic business partners who speak both Japanese and the language of business results.

"We tried two other Japan-focused agencies before WinningField. The difference is the strategic depth — they think like a business partner, not just an ad vendor."

Frequently Asked Questions

Do I need to speak Japanese to work with you?
Not at all. All communication is conducted in English. Our team handles all Japanese-language ad creation, platform navigation, and vendor communication on your behalf.
What budget do I need to get started?
The Japan Entry Pack starts from ¥150,000/month in management fees, plus ad spend (we recommend ¥200,000+/month to run meaningful campaigns). We'll help you allocate budget effectively.
Which platforms should I use for Japan?
It depends on your audience. For B2B: Google Ads + LinkedIn. For B2C/e-commerce: Google, Yahoo! Japan, LINE, and Meta. We'll recommend the optimal mix for your specific product/service.
How is WinningField different from a local Japanese agency?
Most local agencies communicate only in Japanese and focus on domestic brands. WinningField is fully bilingual, internationally minded, and built specifically to bridge foreign companies with the Japanese market.
Can you help with landing page localization too?
Yes. We offer landing page consulting and creative localization as part of our standard service scope.
