Can Lock/Lock Pro's Magnet Accessory for Metal Doors Be Used with SwitchBot Lock Ultra (Only for Japan)？

No, we don't recommend using Lock Pro's magnet with Lock Ultra. Since Ultra has double the torque, using the Pro's magnet during emergency release might cause the lock body to shift.
A dedicated magnet accessory for Lock Ultra will be available soon, stay tuned!
