Bamboo Blade, Asu no Yoichi! Recommendations
Both anime have harem, cute girls, fights, kantanas and kendo :D
If by some stroke of fate you actually liked Asu no Yoichi, specifically the comedic portions, then you'll also enjoy Bamboo Blade.
Both very funny and have to do somewhat with samurai. Asu no Yoichi is more focused on a boy surrounded by girls rather than focused on girls.
Deals with Samurai and martial arts related topics, along with a host of cute girls.
