Born from a simple frustration in Japanese daily life: the search for a coffee mug that could truly keep up. Inomata's engineers, based in Tokyo, noticed how modern routines demanded more from our everyday tools—needing something that could go from fridge to microwave to desk without a second thought. They created this mug using a proprietary, food-grade plastic formula developed in their GMP-certified Japanese facility. Every detail, from the wide mouth for easy cleaning to the precise 350ml capacity, was tested and refined based on feedback from thousands of users. It's not just a mug; it's a solution engineered for the pace of today, which is why it consistently ranks as a top-selling drinkware item in its category across Japan.

The Inomata Lightweight Microwavable Plastic Coffee Mug - Ivory 350ml is crafted from polypropylene (PP), a thermoplastic polymer that serves as the primary material due to its exceptional durability, heat resistance, and safety for food contact. Polypropylene is specifically chosen for its ability to withstand microwave heating up to 140°C without deforming or leaching harmful chemicals, ensuring the mug remains stable and non-toxic during use. This material also provides a lightweight yet sturdy construction, making the mug easy to handle and resistant to cracks or breaks from everyday wear. Additionally, the ivory color is achieved through food-safe pigments integrated into the polypropylene, offering an aesthetic appeal without compromising safety. The inclusion of polypropylene enhances user benefits by enabling convenient microwave reheating of beverages, promoting portability due to its light weight, and ensuring long-term usability through resistance to stains and odors. Overall, these ingredients collectively deliver a reliable, user-friendly product ideal for both home and on-the-go use.
