My one-day visit to Tokyo ended with a visit to Mega Illumini at the Oi Racetrack.
It was a laser show with lights. A 1,000 yen entrance fee. No train station nearby. Tachiaigawa Station is about a 20-minute walk or about a 1,000 yen taxi ride. (Oikebajo-Mae Monorail Station is fairly close but not connected to any network)
It wasn't worth the effort. The show was pretty.... but if you are looking for lights, this isn't the place. If you are looking for music and laser show, this place is okay.
Felt bad, no people. Pretty empty.
Next time, I think I would rather just wander the streets where there are lots of lights.
