A night-time view of the main stadium before its opening, quietly awaiting the start of its second chapter with the clock stopped at 2:46 PM. All 4 stands of the installed night-game lighting create a pleasant and highly uniform lighting environment.
Established in 1997, J-Village is Japan's first national soccer training center. During the period from its establishment until the Great East Japan Earthquake, it saw 500000 visitors per year (roughly 6800000 in total) and was used for training camps for Japan's World Cup team players, as well as by many teams for various competitions and workshops. Its operation as a facility had been on hold due to its use as the base for the combined response by the government and TEPCO to the Great East Japan Earthquake and the accompanying incident at the Fukushima Daiichi Nuclear Power Station, but with that role at an end it recommenced partial operation on 28 July 2018 as a reborn J-Village with fresh appeal. With a facility area of roughly 49ha, J-Village is a large training center equipped with 8 natural-turf pitches, including a stadium with spectator seating, 2 artificial-turf pitches, an all-weather soccer practice field, a wet-weather practice field, a hotel, a fitness gym, arena, pool, and parking for roughly 730 vehicles. With the recommencement of partial operation, 5 natural-turf pitches, 1.5 artificial-turf pitches, and the hotel became available for use, with the 5000-capacity main stadium also able to be opened at the same time due to progress with the reconstruction work being ahead of the original schedule.
An upgrade to LED lighting was carried out for the night-time lighting for the stadium, the No. 1 and No. 3 natural-turf pitches, and the No. 6 artificial-turf pitch, which includes a 400-meter track, with LEDioc FLOOD DUELL high-output floodlights used for each. The existing four-stand system was kept for the natural-turf and artificial-turf pitches, with a total of 48 units of 1100W LEDioc FLOOD DUELL lights (12 lights×4 stands) being installed, and a new average brightness of 380ℓx was achieved, representing an increase compared to the previous design brightness average of 150ℓx. The lighting control board also received a makeover with the addition of dimmer functionality, with the design enabling the selection of illumination patterns at 380, 300, 200, and 100ℓx to match different users and uses. For the stadium lighting, four 18-lamp towers using 1300W LEDioc FLOOD DUELL lights were installed, ensuring the same set brightness as the previous lights with the same number of lamps yet upgrading to LED.
The stadium lighting also has the same kind of dimmer functionality has the pitch lighting. The stadium, natural-turf pitches and artificial-turf pitches all feature vividly restored green turf brightly lit with even light, which has enabled the creation of a bright and comfortable night-game lighting environment.
