Rucksack

A Rucksack is the basic inventory system in Harvest Moon games. It is the amount of items you are allowed to carry with you as you move around. Every game has a different maximum and minimum amount of items your rucksack will hold, and a different way to increase the number of slots available.

Back To Nature
Your initial rucksack can only hold two items, and you can carry one more in your hands, making the total three slots. There are two available upgrades, both of which can be purchased from Jeff at the Supermarket. The Large Rucksack is only available after one week has passed since you purchased the Medium Rucksack.

Friends of Mineral Town
As is the case in Back to Nature, your initial rucksack only holds two items, and you can carry one more in your hands, making the total three slots. There are two available upgrades, sold by Jeff at the Supermarket. The second upgrade is only available after one week after you purchased the first upgrade.

A Wonderful Life
Your Rucksack can hold 280 slots of items. You can sort it into different categories using the C stick. You can also quick access the Rucksack by pressing X. When you set up a stand to sell items, NPC's will buy anything in your inventory, including your tools.

Tree of Tranquility
Your initial rucksack holds 10 items, but there are no distinctions between tool slots and regular item slots. Assuming you carry a full set of tools around with you, your initial rucksack will only hold about 5 other additional items. You can always store away as many tools as you want, if you have no immediate use for them. There are four upgrades available, as soon as you complete Daren's rainbow, and the Tailor Shop opens on Waffle Island.

You can upgrade your rucksack by speaking to Shelly, who runs the Tailor Shop. Instead of paying money, you will need to provide a few items. Your first upgrade will be received for free; just speak to Shelly and she will give a complementary upgrade.

Animal Parade
Your initial rucksack holds 15 items. There are two upgrades available.
