Why there is no info in Japanese? simply because I can´t write properly in Japanese, I´m still a bit away from a couple thousand of kanjis, but I´ll ask my wife to do it in the future, right now my target is the Western Market, so English can do.
About definition of “Japanese” it is designed by a non-Japanese living in Japan, machined in a Japanese factory with Japanese machines operated by Japanese guys that has Japanese faces 
At the end of the day, what matters is how it plays 
I´m happy to see people has good expectations, I´m pretty sure it won´t disappoint you, it is lighter, floatier and faster than the draupnir and it spins longer.
