Toshiba may not have Windows 7 drivers for your Toshiba model. Check on their website:
https/www.toshiba.co.jp/worldwide/region/index.html

If they don't have Windows 7 drivers for it, you will have to re-install Windows 8 via factory recovery.

Always check laptop maker's website before changing the pre-installed OS.
