The chief minister is scheduled to review the development of eight districts during the first phase of his "yatra" over the next five days.
His tour began today from Patilar village in Bagaha, a remote sub-division of West Champaran district.
The "yatra" was earlier scheduled to commence on December 8, but was deferred till today on account of Kumar's ill- health.
At Patilar, the chief minister launched a number of projects and dedicated them to the public.
