Introducing Starzen's Innovative Ready-to-Eat Series 'Rakuraku Otsumami' Requiring Just Microwave Heating

Starzen's Revolutionary Ready-to-Eat Series: Introducing 'Rakuraku Otsumami'

Starzen Co., Ltd, headquartered in Minato, Tokyo, is making waves in the culinary world with its newest product series, 'Rakuraku Otsumami', set to launch on September 1, 2026. This innovative line stands out as the first of its kind nationwide, employing a unique paper tray technology developed by Toppan Co., Ltd that shapes its packaging into a bowl when heated in a microwave. This development caters to modern consumers' needs for both time efficiency and convenience.

Product Features

1. Effortless Cooking
Just heat the product in the microwave—no need for cooking or preparation that requires flames! Thanks to built-in steam venting, you can heat the product directly in its packaging without opening it first, which significantly reduces preparation time.

2. No Serving Hassles & Simplified Cleanup
After heating, simply serve the product in its original bowl shape, eliminating the need to transfer food to a plate. This means no fuss with washing dishes afterward, thereby easing the burden of post-meal cleanup.

3. Eco-Friendly Packaging
Utilizing paper material for the bowl component, this innovative product reduces plastic usage by approximately 48% when compared to conventional plastic trays of similar capacity, emphasizing Starzen’s commitment to environmentally conscious practices. The packaging is stamped with the original Starzen Eco Mark, 'EcoSta', to clearly communicate these eco-friendly efforts to consumers.

Background of Development

As Starzen works to expand its offerings in the household food sector, it aims to meet the needs of busy consumers—particularly dual-income households—who desire convenient and delicious meals while minimizing cleanup time. With increasing awareness of sustainability, the company has also focused on developing products that balance convenience with environmental responsibility.

Following discussions with Toppan about their innovative 'Idadaki Paper Tray', which transforms into a bowl via microwave pressure, Starzen began to develop a product that harnesses this technology. After thorough testing and revisions, the 'Rakuraku Otsumami' series was successfully created, marking its debut as the first product in the nation using the 'Idadaki Paper Tray'.

Functionality of 'Idadaki Paper Tray'

The 'Idadaki Paper Tray' consists of a film lid and a composite bottom made from film and paper. Its innovative design allows it to mold into a bowl shape when heated, making it easy to serve directly after removing the lid. Importantly, it also features a steam venting capability that allows for microwave heating without needing to open the packaging.
