Looking for a tax consultant that tries to reduce my taxes, not only make reports

Where I come from, a tax consultant's main job is not only to make your tax reports, but also to find efficient, clever and legal ways to reduce your taxes.

After talking to some friends which use a tax consultant services and after reading some previous recommendation requests here, I feel like Japanese tax consultant won't be active on recommending different approaches to lower your taxes (For example: Sending money back home to support your family, buying a house and use depreciation deduction).

I'm not looking for anything illegal, but I'm fine with stepping into grey zones here and there as long as it's legal.

Here is some of my personal details, I would love your recommendation of a good tax consultant, and some tips and tricks you might think of.

• My Japanese is not amazing, I need an english speaking consultant.
• I'm NOT a US citizen, and only file my taxes in Japan.
• I'm a salary man with a high income ( over 15M JPY per year ).
• I get overseas stocks as part of my compensation so anyway I need to file an annual tax report.
• I'm about to buy a house.
• My wife and I are considering opening a company, I'm not sure if it would be under both of our names or only hers.

Thanks.
