Sometimes I do work with local tourism companies/organizations - as an advisor (this is often in connection with my volunteer work on the Trip Advisor website), or tour tester or model
It's something I love doing because I've seen how tourism in Hokkaido has changed over the past 20 years.
One company I work with is Hokkaido Treasure Island Travel
This month Koichiro Suzuki, the President, is featured in Nikkei Top Leader magazine...and in the story you can see a photograph of one of the company tours....do you recognize one of those potato picking foreigners???? Last year I went to Kuromatsunai and this is one of the farm visits we did - potato picking and then potato chip making with the farmer's wife.
Many foreigners take these tours to explore Hokkaido, but of course the tours are available for Japanese people too. Why don't you have a look at their website and make plans for this spring???
Even people who live in Hokkaido haven't been everywhere - and you might be surprised of the places and experiences you could try.
