Any journey on the Shinkansen – Japan’s bullet train – is the perfect opportunity to enjoy an ekiben, the iconic bento filled with an assortment of delicacies tucked into a container and eaten in bite-size pieces. The term comes from the Japanese words for train (eki) combined with ben for bento (or “lunchbox”). These little jewel boxes are sold at concessions in train stations across the country and occasionally via pushcarts on trains. Different regions of Japan offer up varieties of local ingredients or specialties, making the ekiben a cornucopia of Japanese cuisine. Before airplanes became inexpensive and frequent in Japan, rail travel was the only mass transportation for long distances.

Our eyes take a moment to adjust to the dim light upon walking into Ladrio. The room is like a vault, its brick walls and floor emitting a scent familiar to anyone who’s ever been in a cave or stone cellar. This mustiness is comforting, however, and the cool air a welcome reprieve from the furnace of the Tokyo summer outside. Soon we can make out several low tables extending back into the narrow space. People sit alone or in pairs sipping coffee or puffing cigarettes. Some converse in hushed tones as Edith Piaf is piped quietly from an unseen stereo. A few heads swivel in our direction but gazes never linger here.

There are times when food is just so profoundly, soul-satisfyingly good that we find it difficult to divert our attention enough to do the socializing often required when eating out with company. The folks who devised Ichiran Ramen must have taken that into account when they set up shop. Their concept is to offer complete personal space so that customers can give their undivided attention to the Hakata-style ramen served there. Imagine being encouraged to loudly suck up your ramen in the privacy of your own personal counter “booth.” Nobody really knows or cares who’s there, and whatever slurping happens there stays there.

Long valued for its medicinal properties, the East Asian stone fruit ume appears in Japan’s oldest pharmacological dictionary, written in 918. Something between a plum an apricot, the ume is more acidic than both and rich in antioxidants. The first mention of umeshu, a liqueur made by steeping ume in usually distilled spirits and commonly translated as plum wine, came centuries later in a book of Japanese cuisine published in 1697. Ume’s medicinal value appears to have carried over, though, as this later work claims that the flavorful tonic both spurs the appetite and counteracts poisons.

After the merriment of sakura cherry blossoms has faded, bringing with it the dreary Japanese rainy season, the hot, humid days of July and August follow shortly thereafter. When summer temperatures and the humidity reach a point of sticky and awful, Japanese people tend to change their diet so as to shake off natsubate, the physical fatigue of summer. In a country where the main religion is nature-worshipping Shinto, most people practice the custom of shun: celebrating nature’s cycles and each season’s profusion of food. Loosely translated, “shun” means the height of nature’s abundance. Each of Japan’s fruits, vegetables and also animal proteins has its own shun, and in the essential and enduring wisdom of Japanese cuisine, that has influenced the preparation of Japanese food for thousands of years.

Nakaochi appears to be a chopped-up mound of Japanese tuna, but it isn’t. It looks like it should be an inexpensive cut of fish, but it’s not. Instead it’s a rare delicacy, a one-of–a-kind culinary experience we can’t get enough of. Nihonbashi Maishi looks like just another restaurant grouped in the basement compound of the Tokyo Nihombashi Tower, but it isn’t. It appears to be an ultra-expensive establishment, but at lunchtime it’s not. It’s a favorite go-to place for true aficionados of Edo-mae sushi and nakaochi. Edo-mae sushi is considered the root of all sushi.

If it weren’t for the dozens of brightly lit signs and paper lanterns promising libations of every sort, you might mistake the two narrow alleys alongside the train tracks on the northeast side of Shibuya station for a derelict apartment block. In reality Nonbei Yokocho (AKA Drunkard’s Alley) is one of Tokyo’s few remaining yokocho (side street) bar districts. Like the much larger and better-known Golden Gai in Shinjuku, Nonbei Yokocho is a collection of aging and tightly packed microbars. Each watering hole is scarcely more than a few square meters, and if longtime regulars aren’t taking up the scant floor space, newcomers may try any number of doors before they find an empty seat.

The warren of streets surrounding the current Tsukiji Market – Tokyo’s main wholesale market – are filled with sushi joints, ramen stands, coffee shops and assorted other restaurants tucked between the stalls and knife makers. Walking around during morning hours one could often wonder where the people who work inside the market have their meals. The gentrification of Tsukiji has brought such an influx of tourists that the early market is now closed to outsiders. Visitors are limited to the outer parts of the market and the food stands. Restaurants are jammed. Beginning at 3 a.m. workers drift into the heart of the market and begin to set up for the 5:30 a.m. tuna auction.

There’s a general rule of thumb in Tokyo that if you see a line in front of a restaurant, it’s probably worth standing in. Maybe that’s how we first discovered Karē wa Nomimono. Or maybe it was the heady scent of fresh curry that wafts out the kitchen door before the restaurant opens every day. As many times as we’ve been back, it’s hard to remember. Touted as a national dish since at least the mid-20th century, curry rice is for many Japanese the quintessential comfort food. While some shops pride themselves on making curry just like mom used to, others are taking the classic dish in bold new directions.

How thrilling to know it’s possible to reach far back into Japan’s gastronomic past merely by visiting Azabu Juban’s Sarashina Horii Soba for a bit of “living history” in the form of a pleasantly simple meal. The Sarashina cooking lineage stretches back over 200 years and is always evident in the shimmering, high-quality plates of buckwheat noodles coming from the kitchen. In 1798, Nunoya Tahei, a Mastumoto City textile merchant famous for his soba skills, founded the Sarashina soba lineage when he was encouraged by Hosina, the local feudal lord, to open a shop making a style of soba popular in the Japanese Alps area of Nagano.

One of the great joys of spring in Japan is anticipating the appearance of sansai, or mountain vegetables. When cherry blossoms begin to flutter on warming breezes, hikers take to the hills to forage for the first wild edibles. Supermarkets mount special displays of packaged (and unfortunately often hot-house-raised) young sprouted leaves, shoots and tubers. Restaurants proudly offer up special seasonal dishes, providing an opportunity to bring the freshness of the outdoors to the table, even in the inner city. A bounty of deliciousness awaits those fortunate enough to get out of Tokyo and roam the hills. Fukinoto, taranome and warabi form a trifecta of green vegetables gleaned from mountain walks. Cooks wait all year to prepare dishes of these fragrant yasai veggies.

We consider ourselves fabulously lucky every time we snatch up one of the ten counter stools or the three-seater table inside the triangular shaped and miniscule Savoy Pizza. Up a few steps as the street curves around behind itself, this smallest of small restaurants is easily missed; the space seems carved out of the corner of a building, almost like the bow of a ship. The best way to find it is to look for the clutch of hungry people hanging around outside, waiting for their slice of Neapolitan-style heaven. It is the kind of place that one is told about and then hesitates to tell more people lest the line outside never end.

Dear Culinary Backstreets, I’m on my way to Tokyo in the next few weeks and wanted to enjoy the cherry blossoms at a typical hanami celebration. Where can I find such a celebration, and what kind of food can I expect and where can I find one? We can fully understand why you want to partake of a hanami, or cherry blossom viewing party, as most Japanese people do. The ritual has been around for over a thousand years in Japan. Cherry blossoms – sakura – will bloom in lavish displays of wonderful pink magic all over Japan, starting on the southern island of Kyushu at the end of March and moving north to Hokkaido by the end of May.

We crept down an almost unmarked flight of stairs, then through a dim, winding corridor and finally pulled back a noren curtain to find ourselves in the world’s only Ippudo ramen location that serves soba noodles instead of ramen. As we seated ourselves on stools around the U-shaped counter, the aroma of tonkotsu (pork bone) broth reached our sinuses and informed us that we had arrived in a place like no other. Shigemi Kawahara opened his first Ippudo ramen shop on the southern Japanese island of Kyushu in1985 and over the next 15 years became a revered ramen master by winning numerous ramen championships on TV.

Editor’s note: This is a new installment in an occasional series about where to wet your whistle in true Tokyo style. Every Tokyo neighborhood has its standing bars, usually near the train station. Azabu Juban’s most popular, Juban Stand, is located on a backstreet running parallel to the shoten gai shopping street. It spills out onto the sidewalk, where old kegs offer patrons the chance to drink a few beers while enjoying life on the street. Inside, a standing area snakes down the bar to the back, ending with a jumble of stools and stairs leading to a small balcony with a few wonky tables for those who prefer to sit and linger.
