Most things has been said. I just want to add here, the taiko isn't that bad as some people said, at least not to me. It dosen't break the taiko rules or guidelines and it isn't something non sense.
We have here just a usual problem: The mapper mapped to the beat and the vocal, which causes some issues and which makes the map looks like messi.
Counting in the no-mods is seriously a problem here, but which isn't a reason for an unrank yet.
[Taiko]
(I will count on some problems here)
00:27:941 (1,2,1,1,1,1,2,3,1) - The song follows the basic rythem of d k d k d k..., but in this case we have it like d k d k d d k d, so even if it is right map to the vocal, it dosen't fit well to the pattern constalation and the beat itself. This causes really messi sounds which aren't nice to listen to. This should be mapped, for example, like d kkd d kkddk d k...
Also a bad issue here is the change form the main beat. In this case the deep bass sound is the main beat, but it changed suddenly to a whole pattern pack with kat as main beat. Not good. This may work for some single patterns, but not for severel seconds.
00:38:279 (2,3,1,1,1,2,3,1) - this would be such small main beat change
00:53:887~01:03:617 - is also fine, since we have one of the rarely cases that the main beat changes in the song itself.
03:47:620 (2,3,1,2,1) - this is a problem. The scrolbar is messed up, which was possible to fix and even if it fit's to the song, it is considerable to leave a gap there or use another sort of beat.
03:53:887 - Really, this kiai shouldn't be here.
Well, that's all. I could make now a really long mod-post with changes which can be made, but the main problem is allready known.
But be warned that such issues can also leed to a remap, since changing the main-beat is leeding to probably messi looking/sounding patterns.

この太鼓マップはモヅーに有りません。それは本当に良いないです。
