Just applied for the DTV from Kyoto, Japan (the Osaka embassy) as a US Citizen. Did tons of research beforehand and saw mixed reviews about whether it was possible. Wanted to share my success! I applied on January 5th and was approved on January 7th with only one request for an additional document (a confirmation of my return travel itinerary to Thailand). I applied under the workcation category as a remote worker. Here is what I included in my application:

1. Biodata Passport page and recent Passport-style photo.

2. Cover letter (included with the financial documents) describing my situation, why I wanted to stay in Thailand, and what documents I included in my application.

2. Financial Documents: I included 6 months of bank statements (it says only 3 are required but many people reported receiving requests for additional proof), my most recent US Federal tax return, my company’s most recent financial statement, and my company’s official US registration and tax ID #.

3. Personal Documents: my job contract with my company as proof of employment (my contract included a clause approving my ability to work remotely, which I called out in the cover letter), a photo of my passport with the Osaka airport stamp, a photo of my inbound plane ticket and a receipt of a coffee I purchased that included the location on it as additional proof of my presence in Kyoto, and a copy of my hotel reservation/itinerary.

Hope this helps someone!
