This elegant Japanese power strip finally solves your office desk's ugliest problem

Kokuyo Energy Line replaces discrete plugs with a continuous slot that supports up to five two-prong plugs anywhere along its length.
It won the Good Design Award 2025 thanks to its accessibility, style and attention to detail.
The Kokuyo Energy line also offers an inclusive design that allows users with upper extremity disabilities to easily use the product with one hand.

Kokuyo is a well-known Japanese furniture giant that focuses on both functionality and aesthetics in its furniture and interior design lines.

It regularly collects Good Design Awards even as it runs a public “live office” where users can test hardware in a work environment, as well as HOWS DESIGN, an inclusive design program that has generated multiple successes.

The Kokuyo Energy Line power strip is one such offering: it comes with a Good Design Award (2025) and is influenced by the HOWS DESIGN program.

A power strip that combines design and functionality

Modern standing desks are a far cry from their older, more mundane alternatives in the workplace or home, and offer a degree of customization that few could have anticipated.

Amid all the improvements seen in monitor arms, cable management, power desks, and even headphone stands, one thing often remains an aesthetic (and often functional) outlier: the modern power strip.

The Kokuyo Energy line aims to solve this problem by offering a single DC outlet that can accommodate up to 5 appliances, with a plug-in-anywhere design and wiring hidden under the table using a minimalist clamp.

It also leverages an inclusive design that allows users with limb disabilities to easily use it with one hand, as demonstrated during the company’s inclusive design workshop at its “HOWS PARK” diversity office.

The Kokuyo Energy Line costs around 7,000 yen (~$50) and comes in black and white colors to suit different themes. It aims to eliminate cable clutter on your desk with a one-size-fits-all approach.

Despite the advances made, the Kokuyo Energy Line also has its limitations: the design means it does not support heavy appliances, with a limit of 5 devices and a power ceiling of 1500W, which may leave users using high-end computers or multi-monitor setups looking for something different.

Unlike competing power strips, it also lacks a surge protector or grounding support, limiting its use to electronic devices that use a two-prong cord.

With no support for 230V power cables or plugs and no current plans to incorporate them, the Kokuyo Energy Line is an impressive but geographically limited power strip offering that suits the company’s target audience looking for an aesthetic upgrade, albeit with serious limitations that could make it unavailable to more demanding consumers in terms of plugs and/or power.
