I will have a few hours of free time in Tokyo next week.

I want to see a light show. It has to be in the city.

Ones like Tama Center Illumination or the Yomiuriland Jewellumation are just too far away for the time I have available.

Is the Tokyo Mega Illumination at the racetrack in Chiyoda any good?
or would the Tokyo Dome Winter Illumination be better? The one near Shibuya train station?.

Any other suggestion would be welcome.
