tbh the paper map tip from the other person is solid, but if you want something more immediate the little tourist info booth near the south exit of Yushima Station has a fold-out map that marks all the tiny alleys in that pocket between Yushima and Nezu. it's a small tan building, easy to miss since it's wedged between a ramen shop and a dry cleaner

the thing nobody mentions is that Hyakuninchō's layout actually follows old Edo-era irrigation canals that got paved over. some of those narrow lanes you'll walk are literally following the path of water that used to flow there. there's a stone marker for one of these canals near the intersection of Suwa-dori and the little street that runs behind the 7-Eleven

for the shrine thing you mentioned, there's a tiny Tenjin shrine on a dead-end alley off Kaname-dori that's only marked by a small stone lantern. it's dedicated to learning so you'll sometimes see students from Todai leaving omamori there. the alley is barely shoulder-width and the shrine itself is maybe 6 feet across

just keep your phone charged and don't stress about the rescue mission thing. the whole area is like 8 blocks by 6 blocks, you can't get lost enough that a 10 minute walk won't fix it

The old canal system is the key to understanding Hyakuninchō's layout. If you look at the pavement in some of the narrower lanes off Kaname-dori, you can still see the stone gutters that follow the original water flow. There's a faded blue sign on the wall of a tofu shop near the Nezu intersection that shows a map of the pre-war water routes, the shopkeeper doesn't mind if you stop to look at it.

For the teahouse you mentioned, skip the one on the main drag and find the one on the dead-end alley behind the Yamate-dori post office. It's called Chōraku and the owner is an older woman who makes warabimochi from scratch every morning. No English menu, no photos on the wall, just a handwritten list of what's in season. She closes when she runs out of mochi, usually around 2pm.

The rescue mission thing is overblown. You can see the Tokyo Skytree from most of the wider intersections in Hyakuninchō, so even if you lose your bearings you just find a clear sightline and head toward it until you hit a familiar street.

You'll be fine getting lost in Hyakuninchō, it's not that big an area. The key is to find the old Yamate-dori and then head east toward the train tracks, that's where the really narrow lanes cluster. There's a small Inari shrine tucked between two houses on a street called Suwa-dori, easy to miss because it's literally the size of a closet.

If you want a structured approach, grab a coffee at the shop next to the Hyakuninchō post office and ask the owner for a paper map. They keep old tourist maps from the 90s that actually show the footpaths and dead-end alleys that Google doesn't bother with. Those maps are a bit yellowed but way more detailed than anything online.

For the teahouse angle, there's one on a lane behind the Tōkyō University annex that's been there since the 1920s. No sign in English, just a noren curtain with kanji for "evening calm." They serve matcha and anko sweets, cash only, closes at 4pm.

solid itinerary, the teamLab tip about midday slots is spot on. for day 3, instead of heading straight to Odaiba from Tsukiji, take a 10-minute walk to Hamarikyu Gardens. it's this old daimyo garden right on the water, total contrast to the market chaos. you can catch a water bus from there to Odaiba, it goes under Rainbow Bridge and drops you right by the ferris wheel. costs about 600 yen extra but the boat ride is worth it on a clear day.

also for day 1, the Met Govt Building deck is free and has solid views but the queue for the elevators can get long around sunset. there's a smaller viewing spot on the 45th floor of the Shinjuku Center Building that most tourists miss, same free entry and way shorter lines. just a 5 min walk from the station west exit.

This is a solid itinerary. I'd suggest swapping the order of day one a bit. Meiji Jingu is right next to Harajuku, so you can hit the shrine first thing when it's quiet, then walk through the grounds and come out right at Harajuku station to avoid backtracking. The Yurikamome Line ride to Odaiba on day three is a great call, the views from the driverless train over Rainbow Bridge are a highlight in themselves.

One thing the guide doesn't mention is that the Tsukiji Outer Market has really pushed up prices for tourists, especially for sushi. If you want a more local and less crowded experience, head to the Uogashi area right behind the main market stalls. You'll find the same quality grilled seafood and tamagoyaki for a couple hundred yen less. Also, for the teamLab booking, the 9am or 10am slots sell out first, so grab a midday entry if you want to avoid the school groups.

for day 2, if you're at sensoji that early, walk through the back of the temple grounds to the small cemetery area. it's quiet and has a great view of the pagoda without all the selfie sticks. also, ueno park's museums are good but the national museum of nature and science has a really cool exhibit on the history of tokyo's subway system with old train cars you can walk through. my kid loved it more than the zoo.

the guide mentions cash but i'd add that some of the best food stalls in ameyoko only take coins and don't have prices posted. just point at what looks good and hand over a 500 yen coin, they'll give you change. i got a huge plate of grilled scallops that way for 400 yen and it was better than any sit-down place i tried
