Actually he isn't lazy. The reason he always take breaks is cause he doesn't want it to be a Fairy Tail, or Bleach
There was an interview and his response was very understandable.
He pretty much stated he loves to write/read manga. But sometime it feels more like a job then something he likes. He said he went through some of his darkest times with YYH and how he felt he rushed it that he was just so ashamed of himself.. He also said sometimes during the start of hxh he would be up nonstop to where he got sick (literally) just to meet the deadline.. So now he pretty much takes a break when he feels a toll might take on. He does it when he feels that vibe.. even though its not consistent its better for him to take a few month breaks and give us 10 chapters vs 10 yr break with nothing
