While Naruto will begin running in HD, new episodes of Boruto: Naruto Next Generations will continue airing at it’s normal Wednesday timeslot for Japanese television viewers and English-subtitled online streamers.
Our belief is that it will begin on the first Wednesday of July with Boruto: Naruto Next Generations episode 14.
All 220 episodes of the original Naruto, also referred to as Naruto Part 1, were in standard definition.
The HD version of Naruto Part 1 will only upgrade the look of the episodes.
