If you are unfamiliar with the game play and back story, it doesn't really matter. It's very simple: control predetermined points and take territory by linking three into triangles uninterrupted by enemy links. In Tokyo, most of the Googlers are playing on the side of The Enlightenment, which gave them a headstart and a stronghold in the Roppongi, Shibuya, i.e., the Yamanote area. The Resistance are relegated to shitamachi, which is actually quite appropriate because it gave The Enlightenment time to obtain higher levels and more territory — resistance should be defined by lower numbers occupying less desirable areas.

A side benefit (really the entire purpose of the game) is improved navigational data (and likely more) for Google Maps. If you can't agree to sharing anonymized location data with Google, then this game isn't for you. I actually see this as not just a good thing, but a brilliant thing. Google's walking directions in Japan, which are still in beta form, need a lot of work. They've gotten better since introduction but will still often direct you across multiple lanes of traffic in locations where no proper crossings exist.
Just ask Apple. You can't build a mapping service from scratch with crowdsourced data.
But you can powerfully augment a robust database with the fundamental background layers already in place. Rather than providing a path to walk, provide two points and analyze the route.
Lose the guidebook for a day
If you've got a day in Tokyo, why not leave the guidebook at the hotel and explore lesser known areas on foot? Many of the "portals" are shrines, monuments, or temples, and often the most interesting of those are not necessarily the largest and most famous.
For getting around, each of the Subway companies (unfortunately there are two independent ones) offer 1-day passes, often for less than the cost of opening a taxi door. Each network is well built out and can get you within a few kilometers of any portal in the 23 wards of Tokyo. Add a few hundred yen for the occasional JR or private rail ticket and you can get just about anywhere.
The best value are the Toei tickets for the services operated by the metropolitan government. All Toei subways (Asakusa, Oedo, Mita, Shinjuku) can be ridden all day for ¥500. However, this is only available during weekends and public holidays during certain times of the year. The standard pass is ¥700 and available all year. This adds the extensive bus system, the rustic Arakawa Line tram, and the Toneri Liner, which departs from Nippori (which is in need of a stronger Resistance presence).

Mobile data options
Japan Communications Inc (JCI) sells a variety of prepaid data-only SIM cards, primarily under the "b-mobile" branding. For around ¥3,000 (perhaps a bit more), you can have mobile data access for portal hacking. Make sure your phone is 1) unlocked and 2) supports UMTS Band 1 (2100 MHz), as explained here. These SIMs can cause high battery usage in some phones, but there is a patch for most rooted phones.
See our comparison of b-mobile SIMs. The easiest by far (but at a relative premium price) are the Visitor SIMs, which can be delivered to a hotel or picked up at major airports.
The "U300" and other reduced speed products might not be the best choice as they have high latency, and Ingress needs to have actions synched between the servers and all clients simultaneously. The 1GB options, which have much fewer speed restrictions, will be more suitable.
The absolute best value is the "1GB Flat Rate" SIM purchased from a major electronics retailer, but this requires activation from a Japanese mobile phone and has no English support other than "pressing 2 for English" during the activation process.
