# Flatbed Countertop Microwaves Panasonic NN-SF57RM Pairs a Turntable-Free Cavity with Inverter Cook By Amy Duong | Published 2026-06-17 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/nnsf57rm References: [shop.panasonic](https://shop.panasonic.com/products/1-cu-ft-japanese-microwave-with-genuis-sensor-2-0-inverter-technology-12000w-nn-sf57RM)  [Panasonic](https://www.trendhunter.com/trends/panasonic-japanese-microwave) [NN-SF57RM](https://www.trendhunter.com/trends/japanese-countertop-microwave) is a countertop microwave that replaces several conventional microwave components with a redesigned cooking system and oven-inspired form. The appliance features a drop-down door with soft-close hinges instead of the typical side-opening design. A graphite finish, compact control panel and flat-front appearance give it a look closer to a built-in oven than a traditional microwave. The interior provides 1.0 cubic feet of capacity and removes the rotating glass turntable in favor of a flat cooking surface. A concealed antenna beneath the cavity floor distributes microwave energy throughout the chamber, eliminating the need for a spinning plate. Panasonic pairs this system with its Inverter Technology, which delivers continuous power rather than cycling on and off during cooking. The microwave also incorporates Genius Sensor 2.0, a [temperature-monitoring system](https://www.trendhunter.com/trends/nuwave-todd-english-iq360) that uses 64 sensing points and measures surface temperatures every 0.1 second to adjust cooking performance automatically.
