Reminder: This is in reverse chronological order. Also (something I should have stated before making this post), title defences in New Japan for championships are often spread out across weeks at the least (outside of multi-night events that each have the same title on the line for each night), or are once every month or so, and this has been the thing in the majority of New Japan's 50+ years of existence.
