I have just visited this site in Hokkaido. Here is the detail (sorry, in Japanese only) of Washi-no-ki insight-tour organized by Mori-machi town office
http://www.town.hokkaido-mori.lg.jp/docs/2023051600034/
The tours are held at designated times on designated days. Like the world heritage Newgrange tour, the participants are to park their own-cars in front of town office, and the guides drove the visitor-bus to the site. I pointed out in the participants-questionnaire that world-heritage-site should provide multilingual guides for the visitors from all around the world.
The tour has been resumed after COVID-19 pandemic, but temporary suspended by the appearance of horrible brown-bears last year.

Now howling robot-wolves has been installed around the site and some of them are placed on a self-propelled cart.
Some more about the robot-wolf:

The excavation of the area around the circle was achieved during 2003-04, lower terrace area digging project continued during 2006-2015. The central gray line of the circle photo is the preservation-cover of later vegetational soil surface (thick layer of much later volcanic ashes from neighbouring mountain over it were removed), and under the several blue coverings there are rain-fall measuring equipments which alarm the peril of landslides because the site thin 2.5m depth over the motorway tunnel has been only preserved.
