I was looking at makita too figuring that being in japan I'd get good service if it sent them in or took them to a shop, but the price gap is quite large.
The bosch drill I'm looking at is 14,150 yen:

A similar makita drill only comes in a set for almost twice as much:
Amazon.co.jp: Makita マキタ 電動工具 18V コードレスドライバドリル&インパクトドライバ コンボキット LCT200W【並行輸入品】: DIY・工具
I think this is due to the marketing strategy differences in Japan v the US.
I thought about ordering from the US, but none of the home centers/amazon will ship tools to japan.
