Understand Account and Contact Relationships
We cant find the related accounts related lists to the contact page layout
何か案外多い質問です。独立させます。
Use page layouts for Contact objects instead of Accounts.
From Setup, enter Contacts in the Quick Find box, then select Page Layouts.
Next to the appropriate page layout, click Edit.
Select Related Lists.
Drag Related Accounts onto the page layout. Because the Related Accounts related list automatically includes all direct accounts and related accounts.

Contactのページレイアウトに追加しないといけない。
