I have just discovered this nice family story set around a used books shop set in the Tokyo neighborhood of Jimbocho. It is a witty observation of the ups and downs of the trade added with the slices of life of the three Karakida sisters who have moved there from Yokohama after inheriting the store and its attached apartment from their grandfather. Tsugumi, the middle sister, has left her job to become the store manager. Her older sister Ichika, who works for an architecture magazine, provides the stable salary to support the loss-making book store. Their younger sister Minoru is finishing high-school and is a"free spirit" with an eye for photography.
The sisters have been used to living on their own since their mother passed away and their father has been working abroad. They all share cherished childhood memories of visiting the bookstore and their moving there represents a new start.
For Tsugumi, the challenge is greater: will she manage to learn the ropes of the trade and turn around the store's fortune, under pressure by the old-time customers to keep the business as her grandfather ran it, and those of her sisters and friends who suggest she should put her own stamp and preferences on the place?
Ichika, the eldest, struggles with broken relationships and tends to drink too much: will she overcome these?
Minoru, the youngest, must cope with the travails of growing up. Will her feelings for her friend Mana blossom into something more?
There is also an element of mystery with the neighbor, Asusawa, who also runs a book shop: is he a rival competitor to Tsugumi, or just a fellow booklover; and why is he so interested in the books stored in the basement by Tsugumi's grandfather?
This first volume introduces the characters and their distinct preoccupations as well as a good deal of suspense. I definitely recommend this series for book lovers and amateurs of family-based drama.

(update) I have now reached volume three, and can only confirm the impressions since beginning the series. The mysteries and uncertainties besetting the Karakida sisters, their bookshop and personal relationships have continued to deepen with an excellent sense of suspense and slow distillation of discoveries and developments. I would also like to confirm my appreciation of the art by Kei Toune. I especially enjoy the rich palette of expressions and emotions with which each of the characters are drawn, be it their poise and their faces, to the point it makes me want to do some fan art for my own exercise.

(new update) I just completed volume 6 of the series, which recently appeared in French. It's been advertised as the last volume. I hadn't expected this and I'm sorry this concludes the adventures of the sisters, as I would have gladly continued a little longer with them, although there is also a wisdom in not keeping some series running too long as well.
As I will not spoil the intrigue I will mainly say this story concludes by leaving a lot of outcomes open for Tsugumi and her bookstore, and Ichika and Minoru, who will also follow their own paths in some surprising ways. We've learnt a great deal of the family history, and its twists have also resolved the mysteries developed around the bookstore's old stock, a famous artist and the neighbor Asusawa. There's some good story-telling running through the series, and the characters have their own distinct endearing traits developed by the author. I continue to recommend this highly!
