Jeff,
Your query lacks significant details so it's tough to make any concrete and meaningful recommendations.
You scratch your head wondering why practically no response to your query.
It's a beautiful Sunday today (
http://www.youtube.com/watch?v=IXu3_jK4QEM0 so I offer sme pointers.
Do some homework at this Japan-Guide; it has extensive info and suggested itineraries you can customise to suit your budget/preferences.
Just as no one-size-fits-all attire (from fatso to skinny), there's no one-itinerary-fits-all types of travellers.
What is your budget (for accomodation, food and transport) in Yen ?
What are your interests and preferences?
Tokyo has two airports (Narita and Haneda)

with maps + discount coupons to major tourist sites (Tokyo Metro-owned)
To use the coupons, you need a physical printed copy obtainable at any Tokyo Tourist Info Center(location info at the HG last page)
* : don't leave home (MY) without these two
JNTO has no office in MY but it has one in SG.
I'm unsure if you write or email JNTO JP or SG, they will post the Handy Guide to you.
Misc
(a) No guides needed as the major sites are tourist-friendly with clearly visible bi-lingual (Japanese/English) signs and often tri-or-quad languages (Chinese/Korean)
You have to pay for the guide's meals/transport and admission fees if any
(b) Trains/subways are easy to navigate after some orientation/familiarisation.
Know what platforms/tracks to use and exits to your desired destination.
There are locality maps at the exits
(c) Check whether a JR pass is suitable(for long inter-city trips on the Shinkansen aka bullet train); an alternative is Kinetsu wide pass(Nagoya southwards to Osaka/Nara)
(d) Suica card (with unusable but refundable 500 yen deposit) is a near-universal charged card convenient for use on trains/subways and even shops; just look for the Suica logo like the typical VISA logo worldwide on shops that accept VISA card.
No fumbling and collecting change/coins and figuring the fares/costs
Note: some exceptions like Kyoto Bus and some not-well-known lines.
The problem is the refund station when you return the card as JR comprises (on Honshu island) : JR East(Tokyo), Central(Nagoya), West(Osaka); each company issues its own card but they are useable at other comapny stations.
Suica is valid for 10 years so you can retain it (like I do) for the next trip within a decade on last use.
(e) Cluster sites of interest by locality to facilitate easier navigation and minimise travel time.
Do note opening/closing times and even the day of the week (some sites close every Monday in Tokyo)
Focus on 2 (max 3) localities per day; pacing is dictated by your physical fitness and transport options
extensive walking so wear comfy shoes
and One More Thing (ala Steve Jobs trademark)
If you are on medication, bring it along in its original packaging and doc's presciption(some drug ingredients are banned)
Once you sketch out a tentative itinerary, return to this forum for critique
Happy planning
