Need help on visa form (working holiday application form)

I'm applying for a Japanese visa and need to fill in the “Address in Japan” section.

I plan to live in a sharehouse (with multiple location) but I haven’t been assigned a specific residence yet, nor make a reservation as i'm waiting for the result of my visa application.

I’m unsure which option is correct:

• Use the head office address of Global Agents as a temporary/planned residence, or
• Use the address of a specific Social Apartment that I intend to apply for, even though it’s not confirmed yet.
• Or just wirte "to be decided"

What is the recommended / accepted practice in this situation?
thank you for your help and Happy Holiday.
