Nope, the Tenkeyless models were originally $115, and the fullsize $129. There's a $5 increase across all Majestouch models, and $10 across the Topre boards.
Either way, outside of Japan there are only two places you can get Filcos - EliteKeyboards in the US, and Keyboard Co in the UK. There are some Japanese sites that sell worldwide, but they are more expensive. Even if they weren't, if there's a problem with your board, warranty may be non-existent, or require you to foot shipping the thing back to Japan. Brian of EliteKeyboards offers a great service, and it's worth the money both for the excellent keyboards and service you get from him.
