TENKU is the planetarium equivalent of a first class cabin: a dome at Tokyo Skytree Town where star projection technology, surround sound and considered scent design combine into shows that are less science lecture, more meditation with a galaxy attached. It is a Tokyo favourite for dates and for travellers whose feet have filed a formal complaint.
Programs rotate through the year, typically pairing hyper detailed starfields with original music and visuals, sometimes with celebrity narration or tie in themes. Narration is in Japanese, but these are sensory productions first and foremost, and non speakers lose little. The seating is part of the draw, with a small number of premium lounging seats that regulars book first; whatever seat you take, shows run to fixed session times, so reserve a slot rather than drifting in.
The planetarium sits within the Solamachi complex at Tokyo Skytree Town. Oshiage Station, served by the Hanzomon and Asakusa subway lines plus Keisei trains, connects directly, and Tokyo Skytree Station on the Tobu line lands you at the front door. From Asakusa it is one stop or a pleasant walk across the Sumida River with the tower looming ahead.
How long is a show? Sessions generally run around 40 to 50 minutes, a comfortable sit.
Does it suit children? Calmer kids enjoy it, but the tone is closer to ambient cinema than a kids’ science show.
What else is at Skytree Town? The observation decks, the Sumida Aquarium and several floors of shopping and food, so the planetarium slots into a half day easily.
