I saw this article down below Odaiba Rainbow Fireworks, Early–Late Dec, 2023 | Tokyo Cheapo
There is wrong info about it
In official web site here : Odaiba Rainbow Fireworks 2018 | TokyoOdaiba.net
It says events will be hold in December 1 , 8 , 15 , 22 , 29
2018 all 5 times
But in the article says the event will continue in january.
If i wrong pls leave me a comment
Thanks for alerting us. As far as we know, the event was for December only.
