It is only possible, if you are a Lawspeaker of a village.
You make a party with your friend, then use a Lawspeaker Government ability "Oath of Allegiance" on your friend's picture in party.
When he becomes a member of your village, he will get the ability to
teleport to Village Totem.
If he is on a reasonable distance from your village of course, if he's too far - he won't be able to teleport because of Travel Weariness limitations.
