If love is the drug, then chemistry explains everything, right? That seems to be the premise of the four-part miniseries “Renai wa Kagaku da” (“Love is Science”; Fuji TV, Mon.-Fri., 11 p.m.).

Four popular young female TV personalities — LiLiCo, Shelly, Mizuki Yamamoto and Chinami Suzuki — discuss the “mystery and wonder of love,” which can be explained by the “power of science.”

Each evening they tackle a different theme. On Monday, it’s “how love is born.” Tuesday they ponder “the deep river separating men and women,” while Wednesday it’s “broken hearts.” Everything is wrapped up on Thursday with “finding love scientifically.” It’s not quite how The Beatles put it, but fair enough.

This year marks the 80th anniversary of the death of Kenji Miyazawa, one of Japan’s most beloved storytellers. To commemorate the occasion, NHK is presenting a series of weekly specials, “Hachiju Nen Go no Kenji” (“Kenji 80 Years Later”; BS Premium, Wed., 10 p.m.), dedicated to different themes associated with Miyazawa, whose value as a cultural touchstone was his depiction of place and the emotional ties that bound individuals to that place.

This week, a group of internationally famous artists provide personal renderings of Miyazawa’s children’s stories in a variety of media, including hand-drawn animation, computer graphics and live-action re-creation. Participating artists include Kazuo Ebisawa, Haruo Inoue and PantoGraph Animation.

CM of the week

DMM.com : The company formerly known as Digital Media Mart once dealt mainly in rental DVDs ordered over the Internet. But it has since expanded into a number of other online services, including stock trading, foreign-currency exchange and even gambling. Its latest ad means to get viewers hip to its new biz in a clever way.

TV personality Rola, famous for her giggly cluelessness, sits on the edge of a sunken bathtub with her feet in the water, talking to her mother on her cellphone. “I’m in a commercial for the No. 3 company in the world,” she says excitedly, as a title explains that in terms of online transactions DMM.com is the third biggest company in the world. She pauses and says, “What kind of company? Hmmm. I don’t know!” Most viewers probably won’t know either, but DMM.com hopes they will want to find out.
