Depending on how large (ie in yen) the "work stuff" is, you probably
won't need to incorporate.

If it is small (ie you are the only "employee", you don't need to limit
liability, annual profit below say 1000man), then just do it as
kojinkeiei. You would automatically be the daihyou equivalent. Just
decide the name of the business, have a stamp made, register the stamp
as your own (or as one of your own), head to your bank and open an
account using the stamp, your personal registered address, and the
account name "会社名 - Danny Wilde" (or whatever your name is as
recorded on your gaigin card. No need in this instance to register the
business as a formal company, do your books on a calendar year basis
and pay your taxes (if required) in March.

If it is a little too large to run as a kojinkeiei, you may want to
limit your liability and incorporate. If you can read Japanese fairly
well this isn't particularly complicated. If you can't read too well
then options include seeking some help from chambers of commerce etc.
Which part of Japan are you in?
