Accessing items in a nested JSON object can be done by chaining property or index notation to traverse through each level of the object.

Here's an example of a nested JSON object:

{
 "name": "John",
 "age": 30,
 "address": {
   "street": "123 Main St",
   "city": "New York",
   "state": "NY",
   "zip": "10001"
 },
 "phone_numbers": [
   {
     "type": "home",
     "number": "555-1234"
   },
   {
     "type": "work",
     "number": "555-5678"
   }
 ]
}
```
To access the value of the `name` property, you can simply use the dot notation like this:
```python
data = {
 "name": "John",
 "age": 30,
 "address": {
   "street": "123 Main St",
   "city": "New York",
   "state": "NY",
   "zip": "10001"
 },
 "phone_numbers": [
   {
     "type": "home",
     "number": "555-1234"
   },
   {
     "type": "work",
     "number": "555-5678"
   }
 ]
}
name = data["name"]

To access the `state` property in the `address` object, you can chain the dot notation like this:

state = data["address"]["state"]

To access the second phone number's `number` property, you can use the index notation like this:

number = data["phone_numbers"][1]["number"]

By using these techniques, you can access any property or value in a nested JSON object.
