I have the same problem - I believe I hit a volume key at the same time as the power button by accident and accessed a root menu, but I can't get out of it! I need some who reads Japanese to get out
I'm so sorry your tablet is in a foreign lanuage and the store was no help to you sanjo7. I know it frustrating. I can provide you with steps to update the language.
Select Apps (アプリ) > Settings ( 設定 ) > Language & Input (言語と入力) > Language ( 言語 )> Select English ( 英語 ) . Let me know if this is helpful.

It sounds like you may have accidentally entered Factory Mode. We are sorry that this occurred.
In order to exit Factory Mode, press the Volume Down button until the last line of text is highlighted in blue. Then press the Volume Up button to make the selection. The device should now restart.
