NHK will host "NHK TECH WEEK" for four days, from May 28 (Thursday) to May 31 (Sunday), 2026, simultaneously holding the public event "NHK Giken Kohkai 2026" and "NHK TECH EXPO 2026" for the first time at NHK Science & Technology Research Laboratories in Setagaya, Tokyo.
This event is open to everyone without prior reservation and free of charge.
This time, we will introduce the exhibition items and highlights of both events.
The lineup condenses NHK's diverse technological capabilities, from cutting-edge research looking 10-20 years ahead to practical wisdom honed at broadcasting sites nationwide. Additionally, the "Drama 10 Convenience Store Brothers" of the NHK Drama Festival will be held at the venue, featuring a corner for commemorative photos with costumes and an immersive experience of the work's worldview through footage shot with an 8K×8K image sensor developed by the labs.
We sincerely hope you will come and experience it directly at the venue.

Highlights of NHK Giken Kohkai 2026
This year, under the theme "Open, Support, Continue," a total of 24 items will be exhibited.
Among these, research results 1 to 16 are all being unveiled for the first time. The exhibition will broadly cover everything from immersive and realistic visual experiences to the results of fundamental research supporting future media.
◆【Exhibit No. 1】 Drone Wireless Transmission Technology
The use of drones is expanding in program production to broaden the range of direction. NHK is researching drone wireless transmission technology to enable stable live video production with drones. This time, we have developed a drone, commonly known as a "flying robo-cam," that enables stable long-distance live transmission to existing base stations using a private wireless circuit for broadcasting operations.
Furthermore, to allow drone use even in areas where the drone's monitoring and control circuit is out of range, we have developed an "IP line relay drone" that can transmit not only video but also drone monitoring and control signals using a private wireless circuit. At the venue, you can see the actual drones and watch videos of flight experiments.
◆【Exhibit No. 16】 Full-Color Transparent Hologram
3D video is an image that appears as if the displayed object exists right in front of you with depth, without using special glasses. At the labs, we are researching technology that can display 3D video without using special glasses. This time, by forming a high-definition hologram on a transparent glass substrate and suppressing light scattering on the surface, we have succeeded in displaying full-color still 3D images while maintaining high transparency. You can observe the real world through the glass and simultaneously view 3D images floating in front of it, experiencing a new visual expression that naturally blends with the real space.
◆【Exhibit No. 15】 Live Output Compatible 15K 360-degree Camera
Aiming for further enhancement of immersion in 360-degree video, we have developed a 15K resolution 360-degree camera using two 8K×8K resolution image sensors. A thin dual-lens bent optical system, which bends light from front and rear lenses to make the camera thinner, was newly developed for 8K×8K image sensors, achieving high-resolution and seamless 360-degree video. It also supports live output of recorded video at 15K resolution, which can be used for checking footage on-site with head-mounted displays or for cropping specific areas of interest from the entire video for 2K program production.
At the venue, wide-angle footage of the Sagrada Familia church (Barcelona, Spain), shot and produced using these technologies, will be shown on a hemispherical display device.
◆【Exhibit No. 10】 Light Field Head-Mounted Display
Aiming to achieve a natural and comfortable VR experience with less eye fatigue, we are researching light field head-mounted displays (HMDs). Light field technology recreates light rays reaching the eye from an object, allowing for the display of 3D images where the eyes can focus naturally, just like in the real world. This time, by devising the display and lens configuration, we have achieved a thinner design and enabled high-definition 3D image display. At the venue, you can actually wear the developed HMD and experience its effects.
◆【Exhibit No. 3】 Lineage Information Technology to Enhance Content Reliability
With the spread of misinformation and disinformation becoming easier due to the prevalence of the internet and SNS, we are researching lineage information technology to create an environment where content can be received with confidence. This technology, based on the C2PA standard*, attaches lineage information with a tamper-detectable digital signature to content at each stage from shooting and editing to distribution, providing it to users.
This event is open to everyone without prior reservation and free of charge.
