  • Panoramic view of the main arena, where the clever use of domestic timber on the underside of the catwalk beneath the truss beam, and the wall surfaces above the spectator seats provides a warm aesthetic in contrast to the base monotone theme of black and grey.

  • The main arena. The vast 4100m² space is illuminated by 80 units of the high-powered LEDioc FLOOD DUELL 800W type floodlights, achieving an average surface illumination level of 1500ℓx.

  • LEDioc FLOOD DUELL 500W type floodlights provide the lighting for the sub-arena, with camera sensors installed to monitor daylight levels and enable lighting control corrections to control the dimming and assist in the transition towards low energy use.

  • LEDioc FLOOD DUELL, mounted on elevated metal fittings for convenience with regards maintenance matters.

  • LEDioc FLOOD DUELL units which provide the light for the main arena have been arranged and installed with careful consideration given to glare levels that competitors and participants may be subjected to.

The multipurpose Ariake Arena is comprised of the 15000 capacity*, 4100m² main arena geared towards the hosting of sporting events to international competition level, and the 1400m² sub-arena which can accommodate a variety of sporting activities as well as smaller-scale events and ceremonies. Conceived as a launchpad for a new wave of sporting and cultural activity in Tokyo, construction of the facility in the Ariake North district which neighbors the areas of Toyosu and Odaiba was completed in December 2019. (* Maximum capacity with temporary seating included)

From the very beginning at the initial design stage, relevant sports and tournament governing bodies were consulted with in the planning of lighting configurations for the main arena and sub-arena, with luminaire installation positions determined through careful consideration of glare and brightness levels that could result from the final design. In order to minimize the brightness of the light source when viewed from below, the luminaires are configured to avert high-luminance lighting away from the line of sight of competitors and participants. Needing to fulfil international competition level sports lighting standards, broadcasting standards for international events, and also the standards recommended by sporting federations, high output LEDioc FLOOD DUELL LED floodlights with high color rendering rated at Ra90 and a color temperature of 5600K were selected to provide the lighting in the main arena and sub-arena; the resulting lighting environment being a high-quality one offering great uniformity and suppressed glare. Also factoring the maintenance aspect into consideration, each luminaire is attached to a dedicated stand and mounting bracket which allow the units to be moved in any direction; the operational safety of the dedicated stand having been fully investigated and assessed through construction models prior to installation.

Not limited only to sports, Ariake Arena is also a venue for entertainment where a wide variety of functions, concerts and cultural events can be held. The main arena is equipped with a DMX control system which enables the execution of intricate lighting adjustments and dimming configurations, and in turn it is envisaged this can present possibilities for lighting controls that are tailored to meet the varying demands of different event organizers; the control panel is linked to the central monitoring system BACnet, making this a highly flexible and adaptable lighting control system. In the sub-arena, camera sensors are installed to monitor daylight levels, enabling lighting control corrections to control the dimming and assist in the transition towards low energy use. With its ability to seamlessly reproduce a kaleidoscopic array of colors, LEDioc FLOOD FULL-COLOR floodlights have been chosen to highlight the dynamic appearance of the building exterior which is characterized by its distinctive concave roof structure, designed to flow in harmony with the waterfront scenery; myriad color variations have been configured for the scheme, from campaign-themed colors to seasonally influenced colors, and from white light to the incandescent color which beautifully accentuates the ripple-like texture of the building's white walls. The implementation of the tablet operated IoT lighting controls system Link-Core allows units to be switched on and off easily, meaning that even in circumstances such as operation during a rotating shift manned by a large number of staff, simple one-touch operations ensure the lighting can be controlled conveniently with no need for a specialist in charge. Where wall-mounted control panels would require a minimum of 2 people to be involved, with one operating the switch from inside and the other verifying the situation at ground level, a tablet-based panel offers the advantage of not requiring a dedicated space. As it can simply be brought out shortly before switch-on, it brings added convenience in that on-the-spot verification of color and operation statuses can now be carried out by one person alone. Using light to accentuate distinctive characteristics of the Ariake Arena such as the curvature of its roof structure and the silhouette shaped by its sloping walls, the beauty of shade has also been beautifully accentuated. Furthermore by optimizing the characteristics of the waterfront site, a gentle light capturing the essence of 'Ariake' (dawn) shines on the water, evoking imagery akin to the purity of light at dawn, or the remnants of moonlight at dawn. Establishing a lit environment that is mindful of its neighboring residents, it is hoped the scheme will add sparkle to the impressive nightscape of Ariake and the wider Tokyo area.
