JapanDocomo's own published example charges ¥125 per minute for calls home from South Korea, and its data travel passes don't cover voice at all.
How NTT Docomo charges for roaming
Docomo doesn't publish one flat international roaming rate — its own page gives Korea as a worked example (¥125/min to Japan) and points elsewhere to a per-country tool for other destinations, including the US.

Frequently asked questions
Do Docomo's travel data passes cover phone calls?
No. Sekai Sono Mama Giga and Sekai Giga Shihoudai are data-only. Voice calls are billed separately per minute, and the rate depends on which country you're calling from.
