> Hi Ishikawa-san,
> I am living in Japan and I am very interested in Placer mining here and your research into good known locations, this is just a hobby by the way and I have found gold in Yamanashi but only a tiny but so far. I am finding it very hard to research here in Japanese, I am wondering if you could point me in the right direction with any location research material?
I must deeply apologize for you as I reply too late.
I recommend you to visit Hayakawa river and its branches.
