Kanou Osamu is a failed writer who has just been evicted from his apartment. As he's trying to figure out what to do, he bumps into his high school friend and roommate Satomi Tatsuo who offers him a place to live on 2 conditions. The first is that he can only stay for one month and the second is that he must listen to everything Satomi tells him.

From CPM:

From the pages of history comes the legend of the Samurai Jubei and the book he was pledged to protect. Now that book has been stolen and Jubei must retrieve it before Japan descends into bloody civil war.

Mugen is a rough-around-the-edges mercenary with a killer technique and nothing left to lose. Jin is a disciplined samurai who's as deadly as he is reserved. Fuu is a young waitress with a good heart and a resourcefulness that emerges when you least expect it. These three unlikely companions are about to begin a journey that will change all of their lives.
It's a dangerous quest for a mysterious samurai that will see our squabbling group of heroes get into and out of trouble more times than they can count (which admittedly, isn't very high). From the cynical gentility of the nobles to the backstabbing of the Japanese underworld, Mugen, Jin and Fuu will face threats from without and within as they hurl insults and throwing stars alike. Ancient Japan is about to get a lethal dose of street justice -- Champloo style. And it will never be the same.

Seikimatsu Tantei Kurabu is dedicated to the very gay and very passionate love of Sherlock Holmes and Doctor Watson. I suppose that it could even be called a doujinshi, since it's blatantly based on Conan Doyle's work, and many of his characters make appearances throughout the story. In fact, the main story is split into three sub-stories -- each one focusing on a different aspect of the Holmes/Watson relationship.

The first story is titled Paris Fin de Siècle, and is a light-hearted introduction to our protagonists. There's a little fluff, a little humor, a sardonic reunion with Arsène Lupin, and a sexually charged scene of boot-licking. (Actual boot-licking. Not the metaphorical kind!) There are also fabulous kisses, cross-dressing criminals and unusual confessions. No smut so far, though. That comes later on. Oh, yes.

The last two stories are based on actual Conan Doyle plots. The second story is based on and named after The Adventure of the Three Garridebs, and the third is similarly inspired by A Scandal in Bohemia. It's wonderful to see Conan Doyle re-interpreted through a yaoi mangaka's eyes! It's particularly rewarding to see Holmes undergo a paradigm shift after Watson is shot in The Three Garridebs; Holmes realizes that he can't take the good doctor for granted anymore, and that his old friend has become so much more than a friend to him.

A military test accidentally sends a modern-day army back in time to feudal Japan. When their actions in the past begin to have an effect on the present, another unit is dispatched to retrieve them. But the commander of the lost unit has other plans. He intends to use his advanced technology to conquer Japan and change his country's destiny. -- {Summary by Mangaupdates.com}

The manga is about the Sengoku Jidai (Warring States Period) of Feudal Japan. The rulers of the land - Daimyo - and their servants - Samurai - fight to get the rule of all Japan. Especially, the most powerful ones are the Devil King Oda Nobunaga of Owari, the Tiger of Kai Takeda Shingen, the Dragon of Echigo Uesugi Kenshin, the Hojos of Odawara Castle

A manga based on the Sengoku Basara 3 action video game. The main characters, Date Masamune and Sanada Yukimura are two warlords who are both attempting to conquer all of the land. Almost greater than their desire to conquer, though, is their desire to fight each other in single combat.

From Bliss:

With the death of Nobunaga, Japan is thrown into a mist of battle once again as the many warlords of the nation try to unite it as one. But can any succeed when faced against Nobunaga's sucessor, Toyotomi and his lust for power thats sets the flame for war as he try to take over the world fulfilling his ambitions of absolute power?

It's 1904. Natsume, the son of a old and prominent family, is cursed with a small, frail body. Because of this, he isn't qualified to enlist in the Japanese forces for the upcoming war with Russia. He is unhappily resigned to becoming a teacher. That is until he meets Daigo, a student. Daigo reminds Natsume that he could inspire and lead just as many future soldiers and leaders of Japan as a teacher, as he could as an officer. Daigo promises to become a great solider under Natsume's tutelage. But unlike Natsume, Daigo isn't in it only for the honor of Japan.

Misia, a young lady from an impoverished aristocratic family that has been in debt for generations, plans to sell herself to the highest bidder for one hundred million livres. However, with her aristocratic pride and a rather handsome butler, will she be able to go through with her plans?

This story in set in the Taisho era (1912-1926) of Japan.

Two years after the famous author Uro vanished, his last manuscript is found at the house of competing author Otogai, who seems obsessed with (or is it possessed by?) his supposedly-dead rival.

By a strange turn of events, three acquaintances; an illustrator, an editor and a stage performer, end up investigating Otogai's odd behaviour. They discover that the writer's garden appears to be haunted by a mysterious camellia bush...and camellia was Uro's favourite flower.

Note: Watashi no Kakurega e Douzo contains a story, Dancing in the Snow, which also features Minami, Ideizumi and Kuzuha. All these stories about the trio are also gathered in the first volume of Rere Shuushuutan, which then continues with new stories about their involvement in various supernatural mysteries.

In the turbulent final years of the Tokugawa Shongunate, Shieikan Dojo was the birthplace of one of Japan's most famous militias: the Shinsengumi. Many of the members have acheived legendary status for their skill, honor and devotion. Under the banner of "loyalty", they would sacrifice their lives for their ideals...

"Soshite Haru no Tsuki" is a series by Miya Ikushima, currently spanning 4 books that give a decidedly yaoi-friendly interpretation of the Shinsengumi. The main pairing is between the young first captain, Okita Souji, and his vice-commander, Hijikata Toshizou, but practically all of the well-known members have their own stories... and plenty of steamy love scenes interspersed with the fighting and intrigue the Shinsengumi were known for.

Vol.1 Soshite Haru no Tsuki (1998)

Vol.2 Akeyuku Sora (1999)
