The image says Graptopsaltria tienta but now the cicada is known as Graptopsaltria bimaculata.
Graptopsaltria genus description by W. L. Distant:
Characters. — Body robust, attenuated posteriorly; head, including eyes, narrower than the anterior lateral margins of the pronotum; ocelli wider apart from eyes than from each other; rostrum extending to about posterior coxae; pronotum with the lateral margins irregularly convex, not prominently ampliated or laminately expanded; anterior femora robustly spined; tympana practically covered ; opercula short, broad, not extending beyond basal segment of abdomen; tegmina opaque, apical areas eight, transverse vein at the base of the second apical area much curved, interior ulnar area not distinctly widened at apex; wings opaque, apical areas six.
The illustration and genus description comes from the journal Genera Insectorum, and a specific article from 1913 by W. L. Distant titled Homoptera. Fam. Cicadidae, Subfam, Cicadinae. Read it on the Biodiversity Heritage Library website.
Cicada season in Japan, like North America, seems to be best from June to September, peaking in August. Different cicada species emerge at different times of the year, but the majority of them are active during the summer.
Cicadas are very popular in Japan, and they find their way into pop culture (Anime, live action kids shows like Ultraman). This photo features a cicada toy when spun, makes a sound, some cicada clicker toys, a plush Oncotympana, a Seminingen (bad guy from Ultraman), and Yotsuba a green-haired girl who has caught a cicada (Lyristes japonicus perhaps):
Cicada News & Photos
The best place, I’ve found, to keep track of which cicadas are out in Japan is Twitter. You can search Twitter yourself for セミ and you’ll find many results — most Tweets are references to pop culture, but occasional photos and actual information about actual cicadas.
These are many of the Twitter feeds I follow. You don’t need to belong to Twitter to view their feeds, but it’s more fun if you join.
