Kigwema can act as your base camp for the trek to both Dzukou valley and Japfu peak. There are a handful of homestays available here. Unless you go during the peak season (winter/hornbill festival), you should be able to easily find rooms. I would highly recommend Akieno's homestay for their unbelievable hospitality. The heritage village, Kisama, which is also the site for Hornbill festival, is a short hike away from here. The heritage complex, showcasing the different tribes of Nagaland, their architecture and customs, is open all around the year, even when the festival is not on. There is also a museum (closed on Sundays) and a park inside the village.
