CiviEvent in Multisite Acting Strange after Upgrade to 4.7
If you look at the two urls you posted you can see that one is /civicrm and the other is /events.

That suggests that when you upgraded perhaps something got messed up in the WP equivalent of settings.php.

if i change out the url and go to

http://subarucherryblossom.org/wordpress/civicrm/?page=CiviCRM&amp;q=civicrm/event/info&amp;id=225

it all looks fine to me. hope that helps.
