My independent Toyota trained mechanic recommended the factory requirement of 90,000 miles.
Hope this is helpful.
Your 2004 Toyota 4Runner has a timing belt if it is a V8. This belt must be replaced every 90,000 miles. Warning: This is an interference engine. Severe engine damage will be done if the belt breaks. If you have a V6 then it has a chain which should last the life of the engine.
The timing of a 2004 Toyota Sienna should at approximately 75,000 miles. Failure to replace the timing belt at the appropriate time can result in costly engine failure.

Well before you ask that question. The real question is how often do you drive your vehicle and how far you drive.
