RYU GA GOTOKU ISHIN
Ryu ga Gotoku Ishin (released in Japan in February 2014) is a spin-off game set at the end of the Edo period of Japanese history (known as the Bakumatsu period), a period when the Tokugawa Shogunate came to an end and imperial rule was restored (Meiji Restoration).
Sakamoto Ryoma is living undercover, with a false identity, as "Saito Hajime" in Kyoto. One year earlier, on the eve of the coup d'état of Tosa, Ryoma's foster father, the man who raised him, was murdered before his eyes. The only lead he had to discover who the killer was is that he used the Tennen Rishin style of fighting. This is a style used by the Shinsengumi, so Ryoma infiltrates their ranks, becoming captain of the 3rd Shinsengumi unit, in attempt to find the killer.

Dharma Exchange
You can exchange the Dharma you earn at the shrines around Kyoto or the shrine at your secondary home in Another Life mode for bonuses such as increased item carrying capacity. You can also exchange Dharma with the Shinto Priest himself for items after you get the upgrade from the Dharma exchange shrine.

Above is the Dharma exchange screen. Use the L1 and R1 buttons to switch to different sections, to make it easier to find what you're looking for.
A lot of the abilities don't show up until you purchase the lower version of the upgrade first. For example - "Kitchen Utensil Expansion (Cooking-Lovers Kitchen)" won't appear until you get the "Kitchen Utensil Expansion (Normal Kitchen)" first.
It's also worth pointing out that none of the Another Life related upgrades appear on the list until you can actually do the Another Life part of the game.
The following are upgrades you can get when exchanging Dharma at one of the shrines.
