Japan is a unique market.
Here's why it's hard to crack alone.

Japan is the world's third-largest economy — but entering it without local expertise is costly and slow.

Platforms are different

Yahoo! Japan holds significant ad market share alongside Google. Meta works differently here. Knowing which platform fits your product matters.

🈳

Language isn't just translation

Japanese consumers respond to tone, nuance, and context. A word-for-word translation rarely converts. You need copy and messaging that feels native.

🔗

The funnel is different

LINE dominates CRM. Trust is built slowly. The customer journey in Japan requires a different approach to nurturing and conversion.

Funnel Audit · E-commerce

Audited a low-converting landing page and identified key funnel issues

I've lived and worked on both sides.

That's what makes the difference.

I'm a bilingual Japan market ads specialist based in Japan, with 8 years of international business experience across Bangkok and Singapore. I understand how international businesses think — and how Japanese consumers behave.

My background spans top-performing sales, international business, and performance marketing, which means I don't just run ads — I think about the full customer journey, from first click to conversion, with both analytical and customer-focused eyes.

I've managed over ¥20M/month in ad spend across multiple platforms, supported businesses entering overseas markets from zero, and run English-language ad campaigns for Japanese brands expanding abroad.

A turning point in my life led me to commit to living each day as my best — on my own terms. Since then, I've backpacked across South America, built new business ideas from scratch, and chosen a path I've designed myself.

I want to be someone who walks alongside you toward your goals. I'll take care of your brand's vision, dig into the numbers honestly, and show up with both integrity and flexibility — because real partnership means moving in the same direction, together.
