F&E for sure bro.
For packaged tours, unless you splurge (and I mean really splurge) on the trip by signing up with Japan tour specific companies eg Prime Travel and JTB, you'd be stuck with those boring run of the mill iternary from regular tour agencies.
And chances are you'd be visiting south to central part of Hokkaido only. And they will make sure there'll be max shopping time n min sightseeing time.

The cheaper the deal, the more severe the issue will be. That's how the trade works.
And when you suay suay join a tour group that have many elder folks, be prep the tour guide may cancel a few of the promised iternaries only to be replaced by more shopping trips.
I suppose its ok if you're those who prefer to shut your mind on your overseas holiday and be herded along by tour guide. But seriously, Hokkaido is too beautiful and heavenly a place for you to waste your time there in this manner...
Trust me, if u can read Chinese characters, you've NO problems at all in Japan. Japs in general are very helpful and patient to foreigners. They will help u even if they don't understand what you're saying.
And with today's tech... you'd be glad to know that Google Translate in your Android phone now comes with offline mode which is a big godsend in helping u getting ard in Hokkaido, just enter what u want in english and Google will translate it into Jap on the fly... with audio readout. So u can show your phone screen to that Jap whom you're trying to talk to.
In return, he can speak into your Google translate directly and the apps will try its best to convert his speech into words for you on screen
