Calling tips

Use headphones or a quiet environment to minimize background noise and improve audio clarity on international routes.
Test connection with a short call (30–60 seconds) to verify audio quality before longer conversations.
Have the phone number written down and ready to avoid delays after dialing.
Schedule regular calls at consistent times to reduce timezone confusion for both parties.
Ask the recipient to confirm they heard you clearly at the start of each call; audio can be choppy on some routes.

Business etiquette

For Japan: Confirm the call time in advance; unexpected calls outside business hours are uncommon in Japanese business culture.
Use formal greetings and allow time for response; communication styles differ between Thailand and Japan.
In Thailand: Casual calls are common; however, respect the recipient's time zone if they are in Japan.
Keep calls concise; long, unscheduled international calls may disrupt the recipient's schedule in Japan.
Follow up with email summaries of agreements or action items discussed on calls.
