Tokyo to New York Time Converter
New York is 14 hours behind Tokyo in winter and 13 hours behind in summer. 9:00 AM in Tokyo is 7:00 PM the previous day in New York on EST and 8:00 PM the previous day on EDT.
Clock changes: Japan has no daylight saving. New York moves to EDT on the second Sunday in March and back to EST on the first Sunday in November, so the gap is 14 hours in winter and 13 in summer.
Why There Are No Shared Office Hours
Tokyo's 9 AM to 5 PM day is 7:00 PM the previous day to 3:00 AM in New York on EST, which runs from the evening before into the early hours. There are no shared office hours, so work between the two cities is mostly handed over, not done together.
Markets show the same split. The Tokyo Stock Exchange closes at 3:30 PM, which is 1:30 AM in New York on EST, hours before New York opens. New York's 9:30 AM open is 11:30 PM in Tokyo.
The Two Slots That Exist
A live call means one side gives up its evening or its morning. Either Tokyo starts early, around 7:00 AM, and reaches New York at the end of its day, or Tokyo stays up late and reaches a New York morning.

"Inside 9 AM–5 PM" is a planning assumption for a standard office day on each side, not a claim about any company's hours.

A Late Tokyo Call That Reaches a New York Morning
If you're in Tokyo and need a New York morning, you'll be working late. A 10:00 PM start in Tokyo is 8:00 AM in New York on EST and 9:00 AM on EDT. Both are the same calendar day.
The reverse is where the date confuses people. A 9:00 AM start in Tokyo is 7:00 PM the previous day in New York on EST and 8:00 PM the previous day on EDT. So a Tuesday morning call in Tokyo is a Monday evening call in New York.
Tokyo doesn't change its clocks, so the one-hour swing is entirely from New York. Check the date for any meeting in the weeks around the second Sunday in March and the first Sunday in November. Going the other way, a 9:00 AM start in New York is 11:00 PM in Tokyo on EST.
