使用タスク: default no-annual-fee card for groceries
1% back as Rakuten points on everything. If you shop on Rakuten Market even occasionally, points pile up fast (SPU multipliers). Annual fee ¥0 for life. Weak points: non-visa foreign transactions have a 2.2% FX markup, and the app is spammy with promotions. For international travel, pair with a Sony Bank wallet card.
