200,000 stocks of Kisuge grow wild in 26ha of Kisugedaira lily plateau. Kisuge begins to bloom in the early summer. This is an impressive scene in the Kisugedaira plateau. Many hikers and tourists visit there every year.

However, an accident happened in 1994. Wild deer ate sprout of Kisuge and it did not bloom well. A number of wild deer was estimated 400.

Various ways were carried out to protect Kisuge from deer, but they did not work well. Someone says, "Planting for deer" ironically.

Finally, Nikko City decided to spread netting around for the protection. It is two meters high and 2115m long totally. The netting will be longer if it worked.

Kisuge is a symbolic flower of Nikko City, but people put a lot of effort on management of Kisuge.
