Answer summary

The TDAC (Thailand Declaration of Arrival Card) should be submitted anytime within 3 days before your arrival in Bangkok. You can do this as early as June 5th or during your layover in Japan. Submitting it before leaving home or during online check-in is a convenient option, as it doesn't need to be exactly 3 days before arrival.

So do it on the 5th, leisurely at home.

Or 6th, before you go to the airport.

You can also do it on your flight if you have wifi. Do it in Japan while on your layover with airport wifi.

Or do it when you land at Bangkok before you get to immigration.

I would do it before I leave home.

It doesn’t have to be exactly 3 days, you can do it anytime within 3 days of arrival.

There are a number of medical questions, some of which would be useless if answered two weeks prior, hence the narrow timeframe.

It doesn’t need to be exactly 3 days, just within 3 days of your arrival date.

If you have no access to a phone or computer you can do it at one of the terminals in the airport prior to immigration.
