To the west of the city is the border of Gifu and Mie prefectures, where the Yōrō Mountains run from north-to-south and the three major rivers of the Nōbi Plain (the Ibi, Nagara, and Kiso rivers) merge. The Tsuya, Ōgure, and Ōe rivers also flow through the city.

History

The area around Kaizu was part of traditional Mino Province. A midden from Jōmon period was found in Kaizu, which includes sea shells, tools, and human remains. These artifacts indicate that the area was settled as early as 2,500 years ago. Around these period, Kaizu was much closer to the ocean and many basket clam shells can be found. In 1319, towards the end of the Kamakura period, the first circle levee was completed. Originally, levees were only on the upstream portion of the city, leaving the downstream side vulnerable to floods. Once the full circle levee was completed, numerous other circle levees were built in the surrounding area. During the Edo period, most of the area was divided between Takasu Domain and tenryō territory under direct control of the Tokugawa shogunate. Many of the events of the 1754 Horeki River incident occurred in this area. During the post-Meiji restoration cadastral reforms, the area was organised into Ishizu District, Gifu. The town of Takasu of created on July 1, 1889 with the establishment of the modern municipalities system. During the early Meiji period, the foreign advisor Johannis de Rijke worked on improving flood control and man of the dikes in this area. The town of Kaizu was established on January 15, 1954 by the merger of Takasu with four neighbouring villages. The modern city of Kaizu was established on March 28, 2005, from the merger of the former town of Kaizu, absorbing the towns of Hirata and Nannō (all from Kaizu District).[5]

Kaizu is home to Kisosansen Park. This is the location at which the Nagara, Ibi, and Kiso rivers meet. A panoramic view of the area can be viewed from an observation tower located in Kisosansen Park.

gollark: I think this is technically possible to implement, so bee⁻¹ you.
gollark: This is underspecified because bee² you, yes.
gollark: All numbers are two's complement because bee you.
gollark: The rest of the instruction consists of variable-width (for fun) target specifiers. The first N target specifiers in an operation are used as destinations and the remaining ones as sources. N varies per opcode. They can be of the form `000DDD` (pop/push from/to stack index DDD), `001EEE` (peek stack index EEE if source, if destination then push onto EEE if it is empty), `010FFFFFFFF` (8-bit immediate value FFFFFFFF; writes are discarded), `011GGGGGGGGGGGGGGGG` (16-bit immediate value GGGGGGGGGGGGGGGG; writes are also discarded), `100[H 31 times]` (31-bit immediate because bee you), `101IIIIIIIIIIIIIIII` (16 bits of memory location relative to the base memory address register of the stack the operation is conditional on), `110JJJJJJJJJJJJJJJJ` (16 bit memory location relative to the top value on that stack instead), `1111LLLMMM` (memory address equal to base memory address of stack LLL plus top of stack MMM), or `1110NNN` (base memory address register of stack MMM).Opcodes (numbered from 0 in order): MOV (1 source, as many destinations as can be parsed validly; the value is copied to all of them), ADD (1 destination, multiple sources), JMP (1 source), NOT (same as MOV), WR (write to output port; multiple sources, first is port number), RE (read from input port; one source for port number, multiple destinations), SUB, AND, OR, XOR, SHR, SHL (bitwise operations), MUL, ROR, ROL, NOP, MUL2 (multiplication with two outputs).
gollark: osmarksISA™️-2028 is a VLIW stack machine. Specifically, it executes a 384-bit instruction composed of 8 48-bit operations in parallel. There are 8 stacks, for safety. Each stack also has an associated base memory address register, which is used in some "addressing modes". Each stack holds 64-bit integers; popping/peeking an empty stack simply returns 0, and the stacks can hold at most 32 items. Exceeding a stack's capacity is runtime undefined behaviour. The operation encoding is: `AABBBCCCCCCCCC`:A = 2-bit conditional operation mode - 0 is "run unconditionally", 1 is "run if top value on stack is 0", 2 is "run if not 0", 3 is "run if first bit is ~~negative~~ 1".B = 3-bit index for the stack to use for the conditional.C = 9-bit opcode (for extensibility).
