I hope the rewards get better as your visitor count does, too. I understand that you're a new faucet, but a couple of things that I would change IMMEDIATELY, if you plan on marketing to the masses...
First, you can't just put "Many Satoshi" for the balance section. This section is important for faucet regulars, as if the balance is low, I won't even waste my time with the captcha and claiming. This should be a physical number.
Secondly, the "Up to 100 yen in Bitcoin..." is confusing, and almost deterred me from even making my first claim. You should replace this with the prize options that are available, such as "300, 350, 500, 1500, 3500" or whatever your payout options are.
I love the design, and I love how minimal the ads are on the site! I wish you the best, and I'll be visiting your faucet regularly
