We are a creative tech firm, building meaningful experiences and helping our partners share their ideas with the world.

Tongullman started in Japan in 2012 as a web and app development team. Since then, we have expanded into the marketing, gaming, art, sports, and event production spaces. Our clients range from local tech incubators to major global corporations.

We specialize in mixing custom software/hardware and new media such as VR/AR/MR, motion sensor, and projection technology to deliver surprising solutions. Our services also include consulting and product prototyping.

We are creatives at heart. In all our work, we strive to stimulate wonder, generate excitement, and communicate authenticity.

Mission Statement

We reject the commonplace and the boring. Our company name is based on the word トンガル (“tongaru”), which means “tapered to a point.” Using imagination as a guiding point, we aim to not just address our clients’ needs, but to target and evolve each underlying vision.
