Basically, security is not bad.
However, don't forget that travelers are foreigners and stand out. To prevent troubles, manage your valuables properly.Also, don't take people's stories too much. If you keep suspicious of people and happenings, your trip will be boring. However, it is dangerous to believe anything. If you are not confident in your trip, it is safer to make some plans in advance.
Recently, troubles at the airport have occurred frequently. At Delhi Airport, a number of incidents occurred in which a Japanese traveler in a prepaid taxi was threatened by a taxi driver and taken to a hotel in a state of confinement, and a large amount of money was rolled up. .. I haven't heard of such incidents these days, but I shouldn't let my guard down.
Even for backpackers on poor trips, it's a good idea to arrange in advance only the airport transfer and the hotel on the first day.
