In-Depth Review TG4G Review ·2026-06-10 · For reference only

What It Is

株式会社グラファイト is a comprehensive IT and creative services company located in Shibuya, Tokyo, Japan. Its services cover web production, campaign websites, custom system/software development, mobile apps, e-commerce setup, CMS customization, SEO/web promotion, server operation and maintenance, corporate/event network construction, PC network maintenance, and design/printing. Strictly speaking, it is not a typical SaaS subscription product, but rather a project-based software development and IT operations service provider.

Core Capabilities

Its core value lies in one-stop delivery: it can handle everything from domains, servers, SSL, design, HTML coding, database/system development, to post-launch access analytics, SEO, advertising, and operations. For e-commerce, it supports marketplaces such as 楽天 and Yahoo!ショッピング, ASP services, EC-CUBE, and fully custom systems. For campaign marketing, the text mentions support for instant prize draws, quizzes, and other キャンペーン, along with an admin dashboard for adjusting probabilities in real time and checking page views and 応募 counts. On the infrastructure side, it offers server monitoring, incident response, LAN/VPN, wireless networks for event venues, and mentions experience building networks for events with around 1,000 participants.

Pricing and Delivery

The website clearly states that budgets vary significantly depending on site scale, whether forms/e-commerce/system development are included, and the method of ongoing operations. The company first listens to requirements and budget, then proposes a plan; consultation and estimates are free. No standard packages, monthly fees, SLA, or payment methods were found publicly disclosed.

Pros and Cons

The advantages are its broad service scope and high level of customization, with the ability to handle websites, systems, servers, networks, and design at the same time. On the security side, it mentions firewalls, SSL, IP restrictions for admin dashboards, and support for building security frameworks related to ISMS and P-Mark. The downside is the lack of SaaS-style product information: there is no free trial, public API, developer documentation, fixed pricing packages, or self-service signup flow. Phone contact may also be difficult because some staff work remotely.

Who It’s For and Access from China

It is better suited for local Japanese companies, advertising/event agencies, organizations that need custom campaign sites or e-commerce systems, and small to midsize businesses without an internal IT department that want to outsource server and network maintenance. Access from mainland China is not reflected in the text, so it is assessed as unknown.
