What It Is

MK is a personal design portfolio and service site run by Mari, positioned as a freelance service connecting the Japanese and U.S. markets through UI/UX, graphic design, website development, and localization. The site indicates that she has lived in the United States for a long time, previously worked in sales in Japan’s financial industry, and has been involved in product design for startups and UI/UX work for enterprise networking companies. She currently mainly works as a freelancer designing apps and building websites.

Core Capabilities

Based on the site content, MK’s strengths are centered on improving product experiences: user interviews and testing, personas, user flows, user journeys, design iteration, and mockup delivery. The main tool used is Figma, with Jira and Zendesk also mentioned. Case study areas include reducing registration drop-off for an online school, redesigning an enterprise networking product dashboard, device activation design, and app onboarding. In addition to UI/UX, MK also offers graphic design for flyers, ads, social media, business cards, and company logos, as well as domain, server, and WordPress setup, basic HTML/CSS, SEO analytics, and blog content writing.

Pricing and Licensing

The site does not disclose any packages, hourly rates, project-based pricing, payment methods, or refund terms. It also does not specify source file delivery, copyright ownership, commercial usage rights, or the scope of ongoing maintenance. For corporate procurement, these details should be confirmed before making contact, especially regarding Figma source files, trademark usage rights for logos, and copyright for website assets.

Pros and Cons

The advantages are that the service scope is fairly broad, combining product design, visual materials, website development, and an understanding of Japanese-English / Japan-U.S. localization. Past projects cover both B2B and B2C, making it suitable for small teams that need cross-cultural communication. The drawbacks are that the publicly available case studies are not very complete, some cases require email-based permission to access, and there is a lack of quantified results, delivery samples, and client testimonials. The team size is also unclear, making it difficult to judge delivery stability for complex projects from the website alone.

Who It’s For

MK is better suited for Japanese companies expanding into the U.S., overseas companies entering Japan, early-stage startups, local businesses, and product teams that need to improve onboarding or dashboards. It is less suitable for companies that require large-scale design systems, long-term on-site teams, or strict procurement documentation, unless contract and process materials can be provided later.

Access from China

The content does not provide information about access from mainland China, ICP filing, or mirror sites, so actual connectivity is unknown. If cooperation is needed, it would be best to contact MK via the website email or LinkedIn first to confirm communication channels.
