Ten tiny Japanese laptops under 1kg you’ll struggle to buy

10 impossibly small Japanese laptops under 1Kg that you will probably never be able to buy (unless you fly there) Features (Image credit: My Navi (originally in Japanese)) (Image credit: Fujitsu) (Image credit: Collin Probst // Future) (Image credit: PC Watch) (Image credit: iiyama) (Image credit: iiyama) (Image credit: Dynabook) (Image credit: Dynabook) (Image credit: MyNavi) (Image credit: iiyama) Wayne Williams published Shaving grams matters more than shaving costs for some Japanese makers Although ultra-light laptops exist everywhere, and while most manufacturers see around 1.2kg as light enough , Japanese PC makers have spent years shaving off every possible gram even going so far as to redesign the chassis, battery, and internal layout from scratch. For this feature, I’ve rounded up ten Japanese laptops that all weigh under 1kg. These aren’t proof of concept devices or engineering demos either - they are real Windows laptops with proper keyboards, modern processors, and a wide range of ports that you could buy today. Yes, some tradeoffs have been made along the way to get to the featherweight svelteness on display, but Japan has mastered the art of balancing form and function. Some of these machines are the latest models, others are updated versions of recent lines, but all of them show how far Japanese makers are willing to go when weight is treated as one the primary aims rather than a secondary goal. 1. Fujitsu’s FMV UX-K3 The FMV UX-K3 is one of the lightest 14-inch Windows 11 Home laptops available, weighing about 634g in its very lightest configuration. It uses carbon fiber and magnesium-lithium alloy to keep weight down while still feeling solid. The 14-inch 1920 x 1200 IPS display has anti-glare treatment. Inside is an Intel Core Ultra 7 255U processor with 12 cores, 16GB of memory and a 512GB SSD. Graphics are inevitably integrated. Ports include two USB-C, one USB-A, HDMI, a microSD reader and a LAN port. It also has Wi-Fi 7 and Bluetooth 5.4.

The battery can manage around seven hours of video playback, helped by a small 31Wh pack. It is listed at around ¥280,280, which works out to roughly $1,804 on Fujitsu’s Japanese store . 2. FMV Zero Lifebook WU5/J3 The FMV Zero Lifebook WU5/J3 also weighs about 634g and employs a rugged carbon body. It offers choices of Intel Core Ultra 5 or Ultra 7 processors, up to 64GB of memory and up to 2TB of SSD storage. The 14-inch 1920 x 1200 display is paired with a full-size HDMI port, two USB-C, two USB-A, Ethernet and a microSD reader. It has Wi-Fi 7 and Bluetooth 5.4. This model trades battery capacity for weight, but still delivers a full-Windows experience. Pricing varies with configuration at Fujitsu’s Japan-only web shop , starting around ¥154,800, the equivalent of $997, for base configurations. 3.
